I am particularly interested in location analytics, blending Business Intelligence with spatial analysis. Examples include retail/real estate site selection, trade area analysis, customer research, and marketing through demographic analysis.

I use Python for process and workflow automation, database reporting & manipulation, and developing new spatial tools.

I've been a GIS professional for 15+ years, most of which using ESRI tools (since Arc/Info 7.x). More recently I find myself using more open-source tools (QGIS, PostGIS, GDAL/OGR, web-based tools) and ultimately choosing "the right tool for the job" rather than being tied to a single vendor or toolset.

comment Count number of attributes for unique field values
The only possible issue with using the Frequency tool instead of the Summary Statistics tool is that Frequency is (ridiculously) only available with an ArcInfo/Advanced license.

comment ArcGIS ModelBuilder model works in Edit windows but not from the “open” window - do you have any experience or advice?
Since you are running your models from ArcCatalog, take a look at Select By Atribute using python script on .Shp file getting error 000840 the value is not a raster layer and Why is it important to use feature layers in ModelBuilder?. I have a hunch your error is related to not using "Layers", which by default are created in ArcMap.

@Chris, you should go ahead and leave a detailed answer of what you found so that future readers of this question will not have to go through the same struggle as you. In a couple of days, you can mark the "checkmark" next to you answer as "Accepted" to close out this question. Glad you found your own solution!

comment Arcpy - What's the best way to check whether feature class has selection?
As noted in the link provided by @Jason Scheirer, using sel_count = len(desc.fidSet.split(";")) will effectively give you the equivalent of a GetSelectionCount utility, which would make it easier to validate using if sel_count > 0: do something.
