Lab 6: DEMs in ArcGIS

1.
Extent of the maps (in decimal degrees)
Top:      47.7611111111
Left:     -122.542222223
Right:   -121.845000001
Bottom: 47.5238888889
spatial reference: GCS North American 1983
datum: NAD1983

For this lab, I chose the city of Seattle in Washington. Seattle has 41% of its area within city limits spanned by water. The land also has many hills and mountains, so for a DEM map, it is aesthetically more interesting.
