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 Naming your Output feature class?
NOTE: If you are using windows pathnames with one slash (\), you need to convert your path to a raw string literal (where you set the env.workspace variable) using the r directive (see the section at the bottom of the page listed under Paths and the escape character)

comment Error when calculate field using VBscript or Python (slice a field)
Have you tried selecting just a single record and running your script above to confirm it works? If you run the script on the entire dataset, and have even one record where !DATA! is blank or null, it could throw this error if the output field is not nullable.

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?
