Expected Skills
·
Convert degree, minute,
second coordinates to decimal degrees, and vice versa
- Determine
the length of a line along a meridian or parallel on a spherical earth
- Determine
the statistics (e.g. average value or sum) of an attribute of a selected
set of features satisfying a logical query
- Be
able to take the parameters of a map projection and interpret what they
mean (focus on geographic, UTM, Albers and State Plane projections)
- Know
the common national data sources for GIS in Water Resources and their GIS
data formats
- Know
the concepts associated with the discrete object representation and field
representation of geography
- Be
able to perform raster calculations and understand the concepts involved
with raster calculation
- Be
able to identify and fill the sinks in a small digital elevation model
- Take a
small grid of elevation cells and calculate the flow direction and flow
accumulation grids
- Define
the watershed of a cell in a DEM grid
- Derive
the Stream definition grid, Stream links grid, Catchments, Drainage Lines
and Drainage points for a small DEM grid

Geomorphologic and Watershed attributes from a DEM derived drainage
network. These include, channel
length, slope, stream order, drainage area, drainage density.
- Derive
the connectivity between Catchments, Drainage Lines and Drainage points
for a small DEM derived drainage network.
