Choose Geoprocessing > Environments > Workspace. Make both the Current Workspace and
the Scratch Workspace
___ IGIS-Arc_ YourInitials
3. For the Output Coordinates, browse to
___ IGIS-Arc_ YourInitials \Spatial_Analyst_Data\
WC_Boat_SA\Wildcat_Boat_SA.mdb\Area_Features\Soils
The Output Coordinate System should be set to “As Specified Below”. For the coordinate
system browse to Projected Coordinate Systems > UTM > WGS 1984 > Northern Hemisphere >
UTM_Zone_18. Scroll down to Processing Extent and again browse to Soils. The four bounding
values should appear. Write them here (to the nearest one-tenth meter).

4. Scroll down further and click Raster Analysis. Click the Cell Size drop-down menu and pick “As
Specified Below”. Type in 2.0. OK the Environment Settings window.
5. Save the map, which you will call Preserve_Environments.mxd, in
___IGIS-Arc_ YourInitials \Spatial_Analyst_Data\WC_Boat_SA
(If you quit ArcMap without saving, the Environment settings may go away. Saving a map
ensures the preservation of its Environment settings.)
6. Quit ArcMap. Restart ArcMap, opening Preserve_Environments.mxd from Existing Maps >
Recent. Recheck the Environment Settings. If they seem alright cancel the Environment Settings
window.
Converting Features to Rasters
The next task will be to convert the vector-based feature classes to raster-based geodatasets.
7. Using List By Source, verify that the T/C shows Soils as data from
