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 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?

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