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 find lat/lon values for every pixel in a GeoTIFF file?
Is the goal to be able to query by Lat/Lon? You could accomplish this with GDAL using the geotransform attribute - I can provide a python example. The conversion could be pre-rendered into a 2 band geotiff (Band1 - LAT, Band2 - LON), but I wonder if it wouldn't be more efficient to do this on the fly. I guess a use case would help.

Sounds like a really specific workflow. What have you tried? What are the results?

comment Problem loading a GeoJSON file using Openlayers
That suggests to me that the call is never happening. Can you post the full openlayers code?

comment What is No Data Value?
If you have GDAL on your system you can use gdalinfo. In QGIS, the properties pane, checkout the metadata tab. It will show you the NDV.

Checkout the firebug network tab. It will likely tell you that you are or are not actually pulling the geojson.

Do you have a proxy setup? This could be a javascript same domain issue? What does firebug (or other inspector) show?

comment .Net to Python - ArcGIS Add-in
Looks like I'm going the .Net update route. It looks like this will be a longer term supported tool as well, so I guess I can port at my leisure as Arc opens more functionality to Python (without having to use IPython or com types gymnastics).
