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 Generate straight lines between river confluences
Can you explain why you are suggesting to use this tool since they are talking about creating a "schematic view" of rivers (which are not usually dual line)?

comment How to identify “true arcs” in Arcmap?
While this won't help to identify the true curves, I agree that using Densify with the Angle parameter is a fast and effective way to densify them very quickly. Using the Angle parameter will also generally only densify the true curves, whereas the Distance option will densify all boundaries, leading to (at least in my tests, using the default parameters) up to a 10x increase in file size.

Are you including Raster (imagery) data on your map? Or just vector?

I am hoping that this "ArcGIS Idea" does not mean that it is impossible to find true curves in 10.0.

comment How to identify “true arcs” in Arcmap?
Here is a thread from 2006 that uses VBA to find true arcs, but since ArcGIS no longer supports VBA, is there a Python or UI way to do this?

comment Can you print cross-hatch area fills like they appear on screen?
Yes, for example, if someone below answered your question, and it was the "best & correct" answer that helped you the most, just click the white "checkbox" next to their answer. It will turn green, and it will then be shown as "resolved".

it would also be very beneficial to the community is you could click the "checkmark" next to answers that solved your previous questions and move the questions into a "resolved" status.

comment Joining tables without losing original field names in ArcGIS for Desktop?
@Johannes, Before working on your data outside of ArcGIS, why not try converting your data to a more modern database format that ArcGIS supports like a file geodatabsae, or even a personal geodatabase. At least then you would know that it is a shapefile limitation, and not an Arc limitation/Issue/Bug.

comment Creating new shapefile based on its attributes with python
Good answer. Using this methodology, you could also very easily script what your particular attribute queries are going to be, and then just run the Select Layer by Attribute tool iteratively over all of your predefined queries.
