comment Insert Cursor fails to write results to table
You might also try moving the creation of the InsertCursor outside the for loop. Because you create the InsertCursor within the for loop, you are actually creating multiple InsertCursor's which may be creating locks on your dataset.

comment Insert Cursor fails to write results to table
Typically, this message comes up when you are trying to insert a value into a field that does not exist or if you are trying to insert a value that is the incorrect data type for the field.

comment How to de-noise a DSM
@RyanGarnett - Unfortunately, we received the Point Cloud from a client without any metadata. There is a classification attribute that has data in it, but I have no idea what the numbers mean. I can't say I've ever done any LiDAR classification personally.

comment GDAL and Python - Don't print GDAL Error messages
I read the Python Gotchas and saw that statement. I like that GDAL does not throw exceptions, but I would also like it if it did not write the error message to sys.stdout. What's not clear is if I call gdal.UseExceptions() will it then disable the messages to sys.stdout or will it both raise exceptions and provide the message?

comment Buffering a Raster with GDAL and Numpy
@Luke - I have considered buffering the vector data beforehand, but I don't think that is necessarily a viable option for me. I am trying to automate a process I have done previously manually. The input data can be points, lines, or polygons and can cover extents up to hundreds of sq miles. When I manually did this process I tried to buffer all building footprints in a 500 sq mile region. ArcGIS crashed trying to buffer so many polygons, but converting to raster worked just fine.

comment OSGeo4W and QGIS 2.0
I did eventually find the .bat and .exe files in the C:/OsGeo4W/bin directory and created my own shortcut. I assumed that those files would be in the qgis directory within the apps folder.

comment OSGeo4W and QGIS 2.0
So I just discovered that the QGIS .exe and .bat files were installed under the C:/OSGeo4W/bin directory. For some reason, I just didn't get any shortcuts on my desktop like I did with all the other apps that were installed with OSGeo4W. And it is QGIS 2.0.

comment OSGeo4W and QGIS 2.0
That sounds like some of the traffic I found online about this. What doesn't make sense is why this would be the default installation from the OSGeo4W installer.

comment Modify Map Service Symbology via Esri JavaScript API
@mapBaker - I am aware of the Esri forums, but my experience has been that SE is a much more active community where I am more likely to have my questions answered. I have never had much luck finding answers on the Esri-specific forums. Also, I tend to work with many different technologies and it's nice to have one resource where I can ask and answer questions related to many different technologies and that's what SE provides.

Thanks John, that is exactly what I suspected, but it's always good to verify suspicions.

comment How to use the ESRI JS API to map SQL Server Spatial Types without ArcGIS Server
@DevdattaTengshe - It's not particularly a requirement. It's just what I am familiar with. I'm a desktop developer primarily who has worked on only a couple of web projects. I'm fairly comfortable with SQL Server, Entity Framework, and ASP.Net (VB.Net is one of my primary languages) and I'm currently learning Javascript while working on this project. In particular, the app I am working on requires calculations and summaries of all the data in a layer and it just doesn't seem feasible to do it client-side.

comment How to use the ESRI JS API to map SQL Server Spatial Types without ArcGIS Server
@DevdattaTengshe - I've heard of Geoserver and would really like to try it some day. I'm still not sure how I would use Geoserver with a server-side web application using something like ASP.Net and Entity Framework. I fear that I would run into the same limits with Geoserver that I am seeing with AGOL.

comment How to use the ESRI JS API to map SQL Server Spatial Types without ArcGIS Server
@DevdattaTengshe - If I were to create a JSON service, would I need my JSON structure to mimic the structure used by the JS API. For instance, would I need to serve up my tables as FeatureLayer objects? RIght now I am working on a project using ArcGIS Online and JS API. The problem is that I can't do any processing in AGOL so any calculations must be done client side. I'm working with only a few layers, but some of them could have hundreds of thousands of features.

comment Which geodatabase type is most appropriate for both open source and ESRI use?
@EtienneDesgagné - As far as I know, they increased the non-SDE functionality at 10.1 to support reading. However, you are correct that there is no support for Geodatabase functionality like topology, versioning, feature datasets, etc. when using a non-SDE database in ArcGIS. On the other hand, Geodatabase functionality will not be available when using the open source tools either and using an SDE database outside the ArcGIS environment is not all that intuitive.

comment Asp code for distance in SQL sever
Do you have the ability to modify your database schema at all? You might try adding a Geography column in your table and convert your Lat/Long varchars to a Geography type. Then you could use SQL to find the distance.

@artwork21 - input rasters are projected and match the coordinate system of the zone feature class.

comment Tabulate Area crashes Python and ArcGIS
I don't save the intermediate rasters, but I do save the result of the SubtractRaster calls. According to the link you provided, which I have seen before, that attribute table is only needed for the zone data, which in this case is vector. All my rasters do have an attribute table as well.

comment Tabulate Area crashes Python and ArcGIS
Sorry, false alarm. It worked the first time I ran it and then upon more testing, I'm getting the same issue again even with SP1.

comment Tabulate Area crashes Python and ArcGIS
I hunted for bugs and did not find any directly related to this, but apparently I wasn't looking in the right place. I installed ArcGIS 10.1 SP1 and it worked just fine. Next is to play around with the new 64bit background processing capabilities. Thanks.

comment Tabulate Area crashes Python and ArcGIS
@gm70560 - I tried the no cell size option as well with no luck. I also tried to rasterize my zone data first and that also didn't help.
