comment What geometric attributes do polygons possess, and how can these be used to filter features?
@BradNesom 3D realm is acceptable, but as above it would have to be simple. Eg. simple polygon average depth.

comment What geometric attributes do polygons possess, and how can these be used to filter features?
@whuber Fair enough. To simplify: Which attributes could be pictured visually by a GIS user? For example, polygon area can be filtered easily by specifying only those polygons with an area > 200m^2 be kept. It would be harder for a GIS user to picture complex angular geometry. So, I'd like attributes that could be comprehended simply to translate to filtering in the GIS.

Is your 'Near' operation the first geoprocessing call you're making on the layers? Is it possible that they have already been opened/loaded in Arc?

comment Is population density considered continuous data and why?
+1 This answer addresses both spatial and non-spatial forms of data continuity, which is important considering the forum in which the question was asked.

comment Is population density considered continuous data and why?
+1 for both above. For a spatial application the consideration of interpolation is important. My answer focuses on density from a non-spatial data standpoint.

comment How to connect places (points) without crossing lines?
Does the point data contain any information/attributes that identify individual points as belonging to a group? Similarly, do the points contain information identifying the order in which they were laid out?

comment Is there a way to take an Extension License from another user in ArcMap/ArcCatalog?
Do you mean deactivating another users' extension and then checking it out yourself?
