Jul 20	comment	Correcting gaps and overlapping polygon (parcels) geometry +1 This seems like a perfect situation for topology rules.
Jul 19	comment	ArcSDE - use native geometry types for later migration away from SDE? Our National (US Fish & Wildlife Service) database just migrated from SQL Server to PostGIS / Postgre working with ESRI.
Jul 19	comment	Pass a variable from Modelbuilder into a Python script Your best bet is to export your model as a python script and incorporate your second script into it. Otherwise, you could use python to get only a portion of the file name and store that as a variable.
Jul 17	comment	Field Calculator Runs In IDLE (2.6.5) but not ArcGIS 10 SP3 Maybe I'm not understanding how your script works -- it looks to me like you're calling variables that are empty because they've been commented out
Jul 17	comment	Field Calculator Runs In IDLE (2.6.5) but not ArcGIS 10 SP3 Correct me if I'm working but it looks like your `exp` and `codeblock`variables are commented out with the multi-line comment
Jul 16	comment	How can I mosaic images in ArcMap without it affecting the colour? Changing the display properties for background or NoData values might help the black portions. Customize => ArcMap Options => Raster Tab (Raster Layer subtab) This will make these properties the default setting for all .mxds
Jul 16	comment	File Geodatabase Open API ESRI Developer's Conference Video
Jul 13	comment	How to draw a Circle with a set radius? Drop a point (x,y), buffer the point 5km.
Jul 13	comment	What is the case for Building Information Modeling (BIM) in GIS? Google has created some interior models for several Museums and says that there are more to come.
Jul 13	comment	How to calculate XY coordinates in Decimal Degrees from projected dataset in model or script? Is it a necessity to keep the XY points in a projected CS?
Jul 12	comment	How can I mosaic images in ArcMap without it affecting the colour? What method did you use to achieve this result? I find that the Raster Mosaic in ArcGIS 10 usually blends colors pretty well.
Jul 12	comment	Add multiple fields in attribute table Sorry -- listing the fields only gives you the location in memory. If you print field in the loop you'll get something crazy. Try field.name (I changed the code in my answer).
Jul 12	comment	SImple model works, resulting script doesn't Heads up: you see error 999999, it's usually a syntactic error (ie incorrect path name, invalid field name -- starts with a number, or it's too long, etc.)
Jul 12	comment	SImple model works, resulting script doesn't +1 you see this problem pop up a lot. People would do well to glance at Setting paths to data in Python.
Jul 12	comment	Numbering Watersheds The SelectByLocation tool gives you an option for NEW_SELECTION so you're not overwriting your last iteration.
Jul 10	comment	Is it possible to define the field displayed on the Identify window in ArcMap? Excellent, I never knew what that expression was set aside for. Thanks!
Jul 10	comment	Adding points to represent non-chosen locations And the 'sites' are polygons I assume -- if the sites aren't changing why not take the centroid of the polygon to represent it as a point location. You could use a `SelectByLocation` based on the point that you DO have (chosen) and assume all other points are 'not chosen'.
Jul 10	comment	Adding points to represent non-chosen locations What are 'non-chosen' points? How do they relate to 'chosen' points? I don't have any context so it just sounds arbitrary.
Jul 10	comment	Field Calculator operation is not working Sorry about that Get Spatial, I saw your last comment after I deleted the question. I'm sure this will pop up again sometime in the future, good point.
Jul 2	comment	Is there a way to programatically force RGB (3 bands) in a raster with arcpy? Thanks, but the original file is a single band raster, this looks like a tool for combining several single band rasters into a multi band composite rather than forcing a single band into a 3-band RGB.
