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)
• Construct a network topology relating junctions and edges (p. 132 of MOW)
• Construct flow direction on a simple network to a sink and assign flow direction attribute (p. 139 MOW)
• 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
• Take a small set of points and construct a Delauney triangulation of them (p. 165 of MOW)
• Construct a contour line on a simple TIN

You can bring a 1-page review sheet to the exam, 8.5” x 11”, with whatever review notes you want written on it (both sides if necessary!).   The exam will otherwise be closed book.
