Exercise 3

Tentative answers:
3.1: There are 12 layers in scene 1.
3.A: There are no layers of point data.
3.B: There are two layers of line data: CN stream and Gloucester County roads.
3.C: There are eight layers of polygons: watershed boundary, cn flood, cn wetlands, Rowan buildings, Rowan parking, Rowan paving, land use and each of the municipal boundaries.
3.D: There are two layers of raster data: elevation and orthophoto.

What happens when I click on GloCo. roads? The roads appear.

3.2: When you click on the far left of a row, that row turns light blue and the town's border lights up.
3.3: The largest municipality in GloCo. is Franklin Township, at 56.47 square miles. The smallest is Newfield Borough, at .78 square mile.
3.4: The greatest population in Glo.Co. in Pop2000 is Washington Township, at 47,114. The smallest is, again, Newfield, with 1,616.

3.5: The cn_watershed extends into Mantua Township, Harrison Township, Pitman and Glassboro.

3.6: The land use of Bunce Hall is marked as commercial/services. That might be accurate, as far as the town's land-use plan is concerned, but it seems inaccurate in the"real world." Perhaps it should be public, or institutional.

3.7: The highest point near Rowan University is The Ridge, which lies west-southwest of the campus.

Finally, in addint the kcsl2001.shp layer to this map, I discover that there are 12 known contaminated sites within the Chestnut Branch Watershed.
