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.

Yep, that's another good workaround if its not possible directly.

@ChrisW, you should add your response's as an additional answer so that it stands out better.

comment ArcPy method to determine ArcMap document version
That's a great function, too. The only hesitation I would have against using this function is that it requires the user to download/install a third party library (oletools) which in some organizations users may not be able to do.

comment How to trigger a Python script from an ArcGIS Desktop “save” operation?
That's a good suggestion if there are no other options. But as @MichaelMiles-Stimson mentioned, the whole point is to provide a "pain free" experience that just happens behind the scenes.

comment Generating Heat Maps with GeoHash
Are you hoping to generate a continuous values heat map (like temperatures based on weather-station readings; example) generated from the points in your GeoHash file, or are you trying to create a choropleth map of polygons that would be associated with areas the points are in?

Is your source geodatabase (or shapefile) layer in "Canada Albers Equal Area Conic" projection, or maybe just the ArcMap data frame?

comment If do not want to use pgRouting then what?
Have you read through the other popular questions tagged with routing such as Alternatives to pgRouting and Are there newer routing algorithms (than Dijkstra, A*) in GIS databases?? If so, how do their responses not answer your question? What additional information might you be looking for?

Have you already tried the other Leaflet plugins listed under the Routing and route search subcategory? How have those worked for you?

comment ArcGIS 10.1+: Allow a model tool to run on any computer
Good find. Another option would be to point all of that intermediate data to the in_memory workspace. It would eliminate specific references to a location on disk, and might even speed up your model processing. Even though Ways to Speed Up Python Scripts Running As ArcGIS Tools references using Python, the use of the in_memory workspace applies the same for ModelBuilder.

comment How do I download all features with a particular tag?
Have you tried the OSM Overpass API? What type of features are you trying to download? For example, roads aren't typically tagged with a locality name.

comment Is there a standard for the specification of .prj files?
I wouldn't call it a standard, but ESRI KB Article 14056 HowTo: Create projection metadata (.prj) files for shapefiles does demonstrate their method for creating a prj from scratch.
