I am a geography Ph.D. student at Arizona State University, with interests in FOSS, big data, spatial algorithm implementation in python, visualization, the application of cartographic techniques / spatial analysis to planetary data (Moon, Mars, Titan, etc.), and remote sensing.

My primary research focuses are in the geocomputation domain.

comment How to generate Digital Surface Model (DSM) from aerial image?
I do not believe that single image elevation model generation is possible without using photoclinometry. I am not aware of a software package outside of planetary science that supports this technique. I also would think that artificial light sources could skew the results in a city setting.

comment several fields and GEOMETRY GetFeatueInfo from Geoserver
Are these multiple geometries per DB row, i.e. something like a multi-point where each point is in its own geometry column?

comment I have n points, how do I find the closest one from a point p by road?
Are you willing to build this using an open source stack or are you looking for a pre-packaged solution?

comment OpenLayers - Weird behaviour when a feature is zoomed in
You have the edit tool selected (I think). Are you flipping the selection based on where you are clicking? I.E, is it always flipping at the same zoom?

comment Basics about Spatial Indexes
But, if you are making a significant number of edits it is possible that the spatial index will reduce access speed. That is, with each edit, if the dbase is recomputing the index you can incur a large performance hit. The timing of updates in a high use environment is important.

comment How to check via Arcpy if ArcMap is currently in an edit session or not?
Can you provide a little more info? What led you to this conclusion for those of us that have not explored the module?

@user18412 How about editing your question with a code snippet to show your implementation?

comment need info on GeoTIFF projection keys
Depending on your licensing requirements, why not just use GDAL to handle these things? The driver is well tested and open source.

comment ArcObjects Geoprocessing Failures
Checked immediately after your last post. I notice that the Arc run of the tool turns the inputs into a list of featurelayers, while I am passing a single feature layer. Passing a list of IFeatureLayers does not work on my end though. (7) - No. If it does, I get a meaningful error.
