My main areas of expertise include the assessment of human development impacts, aquatic habitat analysis, ecological monitoring and evaluation, climate change impact modelling and assessment, spatial statistics, and technical training.

I am particularly interested in international projects and those focused on remote environments where there exists potential for interesting and meaningful analyses using GIS and remote sensing methodologies.

comment What geometric attributes do polygons possess, and how can these be used to filter features?
Thanks @Jakub - the methodology you mention is what I'm looking for. If you have an existing example that would be great, otherwise I'm alright with coding it up.

Point taken @whuber. I suppose I'll have to refine my question and make it much more application specific.

The above example of diameter is something that I would be specifically looking for. I'll take a look for Dan's script - he was an instructor of mine for ~4 years, so it's always nice to still be learning something from him.

How about I go with "easily 'spatially' visualized" and specify that this should be accessible to an intermediate GIS user, not an expert or GIS developer :)

@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?
