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 How to remove only donut holes from polygons using ArcGIS Desktop 10.0?
Very similar to How to remove small “salt & pepper” polygons from a layer?, but using a QGIS process. You could probably work with very similar processes in ArcGIS.

comment Workflow to convert a DWG CAD file to a shapefile
I would recommend looking at How to convert a Visio diagram to a GIS layer, which covers the process of converting a DXF file to shapefile.

comment How can we generate GeoJSON from SQL data with latlong
Does the table include a spatial data type (a geometry), or just lat/long fields? Any other 3rd party addins like ArcSDE? Can you explain your use of the "geoexplorer" tag?

Have you tried adding arcpy.RefreshActiveView() to the end of your script? Does this change anything?

comment Leaflet marker cluster by Administrative boundary
Here is a customized "markercluster pie charts" plugin that supports pie charts showing "edges" by type of event. This may give you some ideas.

Distance is used to cluster the markers. See "maxClusterRadius" in the documentation.

comment Leaflet marker cluster by Administrative boundary
While I'm not sure if this is technically feasible, either, another possibility would be to cluster by an attribute (like Admin boundary name as an attribute of the point). Great idea, though.
