Creating
a Map Layout
ArcGIS is a software program, use=
d to
create, display and analyze geospatial data, developed by Environmental
Systems Research Institute (ESRI)
of Redlands, California. ArcGIS consists of thr=
ee
components: ArcMap, ArcCat=
alog
and ArcToolbox. ArcMap<=
/i>
is used for visualizing spatial data, performing spatial analysis, and crea=
ting
maps to show the results of your work. ArcCatalog=
i>
is used for browsing for maps and spatial data, exploring spatial data, and=
viewing
and creating metadata. ArcToolbox is an
interface for accessing the data conversion and analysis functions that come
with ArcGIS. The ArcGIS software
license comes in three variants: ArcView, ArcEditor, or ArcInfo, wh=
ich are
the low end, middle, and fully configured versions of the software. Any of
these versions can be used for this exercise. The instructions in this exer=
cise
are illustrated using the tools in ArcGIS versi=
on 9.3.1,
but version 9.3 will work fine as well.
=
This
exercise introduces you to ArcMap and ArcCatalog. You use these applications to create a ma=
p of
pan evaporation stations in
To
carry out this exercise, you need to have a computer, which runs ArcGIS. =
You will be working with the following spatial datasets during this exercise: <= o:p>
=
These shapefiles consist of several files (e.g. evap.dbf,
evap.shp, evap.shx). You can get them from this zip file: http://www.ce.utexas.edu/prof/maidment/giswr2009/Ex1/Ex12009Data.zip
=
You need
to establish a working folder to do the exercise on. This can be in c:\temp,
your student directory, or on a memory stick attached to the machine you are
working on. To establish a new account at the CE Information Technology Sup=
port
and Services, go to http://www=
.caee.utexas.edu/itss/
and select LRC User Accounts. =
If you
don't yet have a regular Login account at the LRC, get a temporary guest lo=
gin
to do the exercise.
=
After
you have downloaded the zip file e=
x12008.zip
double click on the file and you should see the Winzip=
,
Alladin Stuffit uti=
lity, or
other zip utility to open the file on your computer (if it doesn’t op=
en
you’ll have to unzip this file on a computer that has a zip utility
installed). Extract all files from the zip file to the working folder that
you’ve set up to do this exercise. You should end up with a file list
that looks something like this. You may see these data within a sequence of
folder names, and if so, click on each folder down through the sequence unt=
il
you locate the required files.
=
=
This
exercise can be executed with any of the license levels within ArcGIS, namely ArcInfo, <=
span
class=3DSpellE>ArcEditor or ArcView. Eac=
h of
these license levels provides access to ArcMap =
and ArcCatalog, which are the ArcGIS=
interfaces used to do the work. When you invoke ArcMap=
or ArcCatalog, it is possible that you will get=
a
message saying that all the licenses for ArcInfo are
in use on the network, or that you aren’t licensed for this applicati=
on. In
that event, you need to switch to another license level of the software with
available licenses. To do this, from Windows use Start/Programs/ArcGIS to invoke the ArcGIS<=
/span>
Desktop Administrator, and select another version. In the LRC, ArcView [Single Use] works best, but in another lab
setting, the ArcView [floating] or ArcEditor [floating] could be the right choice, depen=
ding
on license availability.

Please
note that the following procedure is a general outline, which can be follow=
ed
to complete this lesson. However, you are encouraged to experiment with the
program and to be creative.
A
shapefile is a homogenous collection of =
simple
features that do not contain topological information. The format was introd=
uced
with ArcView 2.0 to simplify the representation=
of
spatial data. A shapefile includes geometric fe=
atures
and their attributes. The attributes are contained in a dBase table, which
allows for the joining with a feature based on the attribute key.
(1) Open ArcMap a=
nd
select the A new empty map opt=
ion.
<=
/span>
(2) Use the =
(Add Data) button to add
the exercise data for this exercise. Navigate to the folder, which
contains the data, and select all three files at once by using the shift ke=
y.
Click the Add button to import the data. If you are using a network drive to
obtain your files use the =
button to add the network drive to =
the
ones that ArcMap is accessing so you can get to=
the
files.
=
In ArcMap,
a layer consists of a reference to a spatial dataset (such as a feat=
ure
class, shapefile or coverage) and a definition =
of how
to display it (legend colors, line thickness, etc.), and a map is a
graphical representation of geographic information. The left panel in the <=
span
class=3DSpellE>ArcMap window is the Table
of contents, and the right panel is the
Display window. In the middle is ArcToolbox, whose use we will cover later. Click this of=
f so
that you just have the Table of Contents and the Map Display panels display=
ed. The
Table of contents lists layers, and the Display window displays maps. As you
can see it is very simple to add shapefiles to =
ArcMap.
(3) Click off the =
check
marks next to the layer names in the left hand column. Click on the check b=
ox
next to each layer name individually to view what features that layer
contains. You can drag =
the
layers up and down in the layer display to alter the order in which they are
viewed on the map. Place the =
counties layer above the Texas layer so that you can see t=
he
county outlines.
=
When you are done
exploring the possibilities of ArcMap, exit the
program. You do not need to save the file since you will be coming back to =
ArcMap later in the exercise.
(4) Open ArcCatalog
Arc Catalog is lik=
e a
Windows Explorer for GIS files. It helps you to quickly explore what data y=
ou
have.
=
(5) On the left pa=
nel,
search for the folder where the exercise data is located.
=
In ArcCatalog,
you can toggle the right panel display between a file tree (Contents
tab), a data view (Preview tab), and a metadata document (Metadat=
a
tab).
(6) Highlight the =
layer
for the Counties shapefile and click on =
the Preview
tab in the right panel. First look at the Geography preview.
=
You can see the la=
yer
represents the outline of
=
If you click on th=
e Metadata tab, you’ll see
descriptive information about the Counties layer:
=
Click on the other=
two
data layers to preview them also.
=
A geodatabase is a relational database that stor=
es
geographic information. A relational database is a collection of tab=
les
logically associated with each other by common key attribute fields. A geodatabase can store geographic information because,
besides storing a number or a string in an attribute field, tables in a
A feature datas=
et is
a collection of feature classes that share the same spatial reference. The =
spatial
reference describes both the projection and spatial domain extent for a
feature class in the geodatabase. Because the f=
eature
classes in a feature dataset share the same spatial reference, they can
participate in topological relationships with each other such as in a geome=
tric
network. These topological relationships can also be stored in the feature
dataset. Note that feature classes in a geodatabase
can exist as stand-alone feature classes, without being part of any feature
dataset.
A feature class=
is a collection of features with similar geometry. There are point, line, a=
nd
polygon feature classes. Two types of feature classes exist: simple feature
classes and topological feature classes. A simple feature class includes
features that have no topological associations among them and features maybe
edited independently of each other. Topological feature classes are bond as=
one
integrated topological unit, such as a geometric network that we’ll
explore later in this class.
(1) To create a ne=
w geodatabase in Arc Catalog first right click on the f=
older
that contains the data for the exercise. Select New/Personal Geodatabase and a new geodat=
abase
-- called New Personal Geodatabase.mdb and represented by an icon with the
shape of a cylinder -- will be created. Note – a File Geodatabase
is an alternative form that stores the data in a file system instead of as =
an
Access file. It can be faster to do this but this is not important for this
exercise.
=
(2) Name the geodatabase Ex1Data (the =
geodatabase
will keep its file extension mdb regardless of
whether you included it in the name or not). You can right click on the
=
When first loading=
data
into a geodatabase, it is important to think ab=
out
the data and how they are related. As mentioned above, in geodatabases
the data is placed in feature classes that are then organized into feature
datasets. A geodatabase can have one or more fe=
ature
datasets. Each feature dataset has a single reference frame, which includes=
the
map projection and map extent. It is possible to define the reference frame
after the creation of the feature dataset and before data is loaded.
We will create a n=
ew
feature dataset within this geodatabase to defi=
ne the
spatial reference of our data. Right click on the Ex1Data.mdb geodatabase and select =
New Feature Dataset.
=
Name the new featu=
re
dataset Texas, and hit Next to set the co
=
and hit Next to set the coordinate system for these data.
Select in this screen, and then select Texas.shp.
=
This has the effec=
t of
assigning the coordinate system of the Texas.shp
theme to the Feature Dataset.
=
Click Add and then Next and you will be asked to select a vertical coordinate system
=
In this case, we
don’t have vertical coordinates (z-values) so we’ll just accept
“none” and hit Next. You’ll now be asked to select tolerances for
various coordinate systems. Just “accept the default resolution”
and hit Finish. Note that this
process of setting up a Feature Dataset in ArcGIS
version 9.3 and 9.3.1 is significantly different than in earlier versions o=
f ArcGIS and this avoids a problem of your being forced=
to
set a spatial bound on the extent of your data that caused considerable
difficulties in this class in previous years.
=
Now you have a new
feature dataset called Texas.
Don’t worry if you see a screen that says that Metadata has not
been set for the selected item.
=
And if you view th=
e Spatial component of the Metadata for this Texa=
s feature
dataset, you’ll see that you are using NAD_1983_Albers projected coordinate system.
=
And if you click on
details, you’ll see some more information about the parameters of this
coordinate system. You’ll learn what this means in your lecture on map
projections and coordinate systems!
=
If you check the f=
ile
list for the shape files that you opened at the beginning of this exercise,
you’ll find that all the shape files have a .=
prj
file which describes their geospatial coordinate system.
If you open the Texas.prj file in MS Word, you=
217;ll
see the following information:
PROJCS[&q=
uot;NAD_1983_Albers",GEOGCS["GCS_North_American_1983",DATUM[=
"D_North_American_1983",SPHEROID["GRS_1980",6378137.0,2=
98.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.=
0174532925199433]],PROJECTION["Albers"],PARAMETER["False_Eas=
ting",1000000.0],PARAMETER["False_Northing",1000000.0],PARAM=
ETER["Central_Meridian",-100.0],PARAMETER["Standard_Parallel=
_1",27.41666666666667],PARAMETER["Standard_Parallel_2",34.91=
666666666666],PARAMETER["Latitude_Of_Origin",31.16666666666667],U=
NIT["Meter",1.0]]
This information i=
s what
has been displayed in a more readable form in the metadata file that
you’ve just looked at in ArcGIS. Notice also in the list of files g=
iven
below that you now have two Microsoft Access files in this list called Ex1D=
ata,
one which has 536KB and actually contains the data, and the other which is =
1KB
which is a “lock file” that exists while the ArcCatalog
or ArcMap applications are open to prevent this=
file
from being altered with another application while you are working on it in =
ArcGIS.
It happens that all
these shape files have the same coordinate system as the Texas shape file so
when they are imported into the geodatabase, th=
ey
overlay correctly in the same spatial reference. If you get shape files or =
coverages with undocumented coordinate systems, it ca=
n be a
real headache to figure out what the correct coordinate system is. Fortunat=
ely,
ArcGIS version 9 automatically documents the
coordinate system on each shape file, but earlier versions of ArcView did not do this, and you may encounter the pr=
oblem
of undocumented coordinate systems when loading older shape file data.
To import the shape
files into the feature dataset, right click on the

You’ll see a=

After creating the=
geodatabase, the feature dataset and the feature clas=
ses,
the ArcCatalog tree looks like this:
=
Note that the feat=
ure
classes Texas, Counties, and Evap could have be=
en
created outside the feature dataset Texas, but since they share the same co=
ordinate
system, it was decided to group them together within the feature dataset. <=
span
style=3D'mso-spacerun:yes'> If you have data in other
coordinate systems (defined with a .prj file) t=
hese
will be automatically converted to the coordinate system of the feature dat=
aset
during the importing process.
=
We will
now add the feature dataset that we created in ArcCata=
log
to an ArcMap document.
(1) Close Arc Catalog. If you look in Windows Explorer at=
this
folder, you’ll see that the lock file has now gone away.
=
You can
display data in ArcMap when ArcCatalog
is open on the same data, but you cannot alter these data in any way.
=
To
display the spatial data of the Texas feature dataset in a map, now open ArcMap. You can
launch ArcMap=
from within A=
rcCatalog
using =
or you can open ArcMap from the Start menu=
as
you did before.
=
(2) In ArcMap, =
click on
the Add Data button, =

the
effect of adding all the feature classes in the feature dataset to the ArcMap display. You can add individual feature classes

order
in which the feature classes are displayed is the order they are listed in =
the
Layers.
=
(3) Save your work=
in ArcMap by choosing File/Save and, after naviga=
ting
to your working directory, naming the file Ex1 (the file will be
assigned the extension mxd). When you do this, =
the
Ex1.mxd file contains the file location of the geodata=
base
and the symbology you’ve chosen for the m=
ap
display. You can shut down Arc Map and then invoke Arc Map again and reload=
the
same map display by clicking on Ex1.mxd. Note, however, that if in the mean
time you’ve relocated your geodatabase, <=
span
class=3DSpellE>ArcMap will go back to where you had it at the time t=
he map
file was saved.
=
__________________=
______________________________________________________
If you open your <=
span
class=3DSpellE>ArcMap Ex1.mxd file later from another location in yo=
ur
file system, you may see a red exclamation points beside your feature class=
es. If
this happens, in ArcMap, right click on the fea=
ture
class use Data/Set Data Sources to relocate the file location where =
the
corresponding data are now stored and your map will display correctly again=
. It
does not matter where the Ex1.mxd file is stored, you can move that around
wherever you want, but it does matter where the data referred to in that fi=
le
are stored. ArcGIS 9.3 is a good deal cleverer =
at
dealing with file locations than earlier versions were so you may not encou=
nter
this problem.
=
Ok, let’s co=
ntinue
on with the exercise.
(4) To change the
appearance of a map display, you can access the Symbology menu just by dou=
ble
clicking on the Symbol
=
displayed in the ArcMap
Layers, and you’ll get the S=
ymbol
Selector window
=
Click on the symbol
color box, make your selections for the Fill Color and the Outline
Color, and click OK, twice. Follow this procedure to modify the display=
of
the Counties layer. Hopefully, the new map looks better than the original o=
ne. You
can show the outline of the State of
More complicated s=
ymbol
shading that has the color and size of the symbols varying according to att=
ributes
of a feature class can be manipulated by accessing the Properties of=
the
Symbology of the Feature Class.
To Save
this map display, use File/Save As
in ArcMap and save the resulting file as Ex1.mxd.
=
4. Using Base Maps from
Up to this point w=
e have
just used local GIS data in our display. Lets
instead using base maps from the ArcGIS Online.=
User File/Add Data From
ArcGIS Online:
and you’ll see a web pag=
e pop
up that looks like:
Click on “World Street Map”, the seco=
nd map
from the left on the top row of maps.
Click Ok on the screen “Opening World_Street_Map.lyr”
You’ll see a
background map appear behind your Texas display:
Click on the Count=
ies
theme and use the Symbol Selector to make the theme “Hollow” so=
we
can see through it to the background map, and the new display appears as:
Zoom in to Travis =
County
by Austin in the center of Texas, and lets
examine the evaporation site by Lake Travis to the Northwest of the city:
Lets label the sites with their
names. Right click on the
Now, right
click on the Evap theme again and select=
Label Features, and you’ll =
see a
nice label Mansfield Dam appea=
r by
the site next to Lake Travis.
If you zoom in a b=
it
closer, you can see just where the site is located near Lake Travis. Mansfield Dam is the dam that is a=
t the
downstream end of Lake Travis.
Now, lets look at some imagery for this location.
And now you’=
ll see
the same information displayed against a background map of orthoimagery:
Pretty cool!!
And lets
zoom in a bit to see more detail:
I used the Evap Properties to change the Label color from Black =
to
Yellow to make it show up better against the dark background of the orthoimagery.
Ok, this is pretty
cool! You can see how you can=
use
standard road base maps to locate your area of interest, and imagery to
understand the context of a site. This is the first time in ArcGIS
that we’ve really been able to do this kind of thing, which was
popularized in the GIS field by Google Earth and Microsoft Virtual Earth.
Use File/Save As to save this new map display as Ex1BaseMap.mxd so that you can get it back later if you need it=
.
5. Accessing and
Querying Attribute Data
=
Numerical
and text information stored in the fields of the geoda=
tabase
tables are called attributes. To access attribute data of the feature
classes at a specific location:
=
(1) In ArcMap use F=
ile/Open,
to open your previously saved Ex1.mxd from Section 3 of this exercise.
=
=
Click on
the Identify Features tool =
which is contained within the
“Tools” menu. If you don’t see this set of tools on your =
ArcMap document, use View/Toolbars and click o=
n Tools
to make it appear.
=
This is the toolbar you need.
=
(2) Click on the f=
eature
on the map you are interested in, and in the Identify Results window,
select the object you are interested in. In the figure, attribute data for =
the
=
If you inadvertent=
ly
close the Tools menu you just =
used,
you can open it again from the Vie=
w
(3) Tables that co=
ntain
attribute data of a layer are always called Attributes of <layer name=
>,
and contain a field called Shape. The field Shape displays the words
Point, Line or Polygon, but it really stores a geometric object with the sh=
ape
of a point, line or polygon. To access attribute data of an entire layer, i=
n ArcMap: =
right
click on the =
Evap
layer name in the table of contents, and select Open Attribute Table:
=
And if you scroll =
down
and click on =
ObjectID 44 you’ll see the record t=
hat
contains the attributes of the
=
(4) To Clear a Selected featur=
e and
select a new one, use: Selection/Clear Selected Features in the ArcMap toolbar:
=
=
Selecting
features from a feature class involves choosing a subset of all the feature=
s in
the class for a specific purpose. Feature selection can be made from a map =
by
identifying the geometric shape or from an attribute table by identifying t=
he
record. Regardless of how you select an object, both the shape in the map a=
nd
the record in the attribute table will be selected. To choose a particular =
data
layer for selection use Selection/Set Selectable Layers and then cli=
ck
off the layers that you don’t want to have selected. Be careful when
using this Set Selectable Layers function because if you later want to sele=
ct
features from another class, you’ll have to go back and change this
selection to your new class.
=
=
=
=
(1) To select an object from th=
e map,
in ArcMap: click on the Select Features tool =
, in the Tools menu
(2) Zoom to the fu=
ll
extent of the map, by using the =
button on the Tools menu. Click on =
the Counties polygons you want to sel=
ect.
To select more than one object, press the Shift key and hold it down while =
you
click on the additional objects. Selected objects are displayed with a light
blue outline, although the color might change depending on your settings. T=
he
corresponding attribute table records have also been selected. You can veri=
fy
this by opening the Counties attribute table, and hit Selected at the bottom of the attribute table to show just the
Selected Counties.
=
(3) To clear your
selection, right click on the layer name, and choose Selection/Clear
Selected Features.
Charts are useful
because they allow you to visualize trends in data. Ar=
cMap
has chart-making capabilities. We will plot a chart of one or more records
selected from a geodatabase table.
(1) Use Selecti=
on/Set
Selectable layers to show only the Evap data
layer.

Select the two
evaporation points that are located in
You can also get a=
t this
Chart menu from the ArcMap tools menu as shown =
below:
=
(2) You will be ma=
king a
Vertical bar chart (the default option). The next screen will allow you to
indicate the data to be used in the graph. Here is a graph of the Annual
Evaporation (=
Ann_Val)
of the two stations plotted against a backdrop of all the stations in Texas,
indexed using ObjectID:
=
Hit Next and edit the graph properties to make them nicer. Click off to get rid of the legend on the rig=
ht
hand side. Use to customize the color display of y=
our
data.
Hit Next to Customize the Graph Title and Axis titles on the graph.=
Press Finish. You
have created a graph in ArcMap!!
=
Save
your ArcMap document Ex1.mxd so that you can retain this display.
=
Another graphing
option is to make a chart in Excel using the dBase tables given by the
evaporation shapefile. Open the evaporation
attributes table evap.dbf as a table in Excel. Use Files of Type: dBase files in Excel to focus =
only
on .dbf tables when you open the table. Select the stations you want to plo=
t,
copy their records to a new worksheet, delete the columns you don't need th=
ere,
and then create a chart. Here is an example chart created this way. The
column headers have been renamed from Jan_Val t=
o Jan,
etc to make the Chart x-axis more attractive to view. The legend has been m=
oved
to the top of the chart to allow a wider spacing of the data in the chart. I
copied the data for Mansfield Dam and Austin airport into a new spreadsheet=
to
make this chart.
=

=
You can draw lines=
to
relate the location of the measurement stations and the data plotted on the
graph using the Draw a Line tool from the ArcMap Draw
toolbar (to display this Toolbar, use View/Toolbars and select Dr=
aw).
This draw toolbar works the same in ArcMap as i=
t does
in other MS applications. It is important to show some association between =
the
data plotted on the chart and where these data were measured on the map so =
that
you can figure out which data series was measured at what location.

tool.

Properties to resize them. You can also insert a North Arrow and a Scale Bar by using the Insert
menu in ArcMap.
=
When you put up the
scale bar it is in meters because those are the map units used in the
data. If you click on the sca=
le bar
you can redefine the distance units (I have used miles) and if you expand or
contract the scale bar you can show a desired spacing of these distance uni=
ts.
Your map might loo=
k like
this:
You can export you=
r map
from ArcGIS using File/Export Map from the ArcMap men=
u, and
you can store this as Ex1.emf =
in
your data file. Then you can add it to a Word document using Insert/Picture/From File and load=
this emf file, as shown below. Pretty cool!
Then you can add i=
t to a
Word document using Insert/Picture=
/From
File and load this emf file, as shown below=
. Pretty
cool!
Here's another opt=
ion:
suppose you want to take a chart in Excel and add a map to the Chart to show
where the data apply. I=
n the Map display (not Layout Display) =
use File/Export Map to create another=
.emf file, and then in Excel you can use Insert/Pictur=
e from
File to place this in an Excel graph. You can see that in this map, a nice
color association between the symbols on the map and the bars on the chart
makes it clear which data series was measured at which location. This chart
shows a different pair of evaporation stations that are color code at their
geographic locations so you can see how the pattern of evaporation varies
geographically.
The manipulations =
just
described transfer objects from one application to another.

A more general pro=
cedure
is to simply copy the screen to the clipboard and crop out the part that you
want, saving it to a file for later use. That is how all the images in this
exercise were prepared. To copy any image, hit Print Screen on your
keyboard (this copies the Screen onto the Clipboard). If you only want to
capture the active frame, press Al=
t +
Print Screen. This is convenient if you only want to capture an attribu=
te
table or graph within ArcMap as opposed to the =
entire
screen, therefore no cropping is necessary.
The image copied f=
rom
the screen can be pasted directly into word then edited using the Format tab. Double click the past=
ed
image to automatically open the Format tab. The Crop function allows you to trim out the unwanted portions of t=
he
image.

In the
presentation of information on maps and charts it is important to include
sufficient labeling detail so that the information can be clearly and
unambiguously interpreted. You
should include a scale bar to indicate distance, a north arrow to indicate
direction and labels or legends with units wherever they are needed to
interpret map or quantitative values.
Lets
see some nice cartography!!
