Ok, thanks for letting us know. What is your question? Assuming it is "how to get this to work", then: what have you tried? What do you think is the error? What browser are you running? What line number is the error on?

comment Can't read returned geojson
I see your problem. What I would suggest is to call your jsp with just the point, sanitize the point in jsp and build the SQL query there.

comment Problems while adding KML layers using openlayers in Internet explorer
Please provide details, preferrably a code example or a minimal example that shows your problem. There can be dozens reasons this isn't working. Althoug, the easy answer here is: "because IE is shait;)"

comment Creating nanoscale DEM with GDAL
My code so far can be found here: github.com/atlefren/AFMParser Seems to work for me, does this seem sane? (see especially test.py) Sorry for the lack of test data, difficult to publish data that's part of ongoing research.

comment Creating nanoscale DEM with GDAL
The reason I (think) i need a CRS is this: if i just create, say a GeoTIFF without assigning a CRS, the unit of measure will be pixels. What if I want to measure distances? And, what if I have two AFM scans and know how they relate to each other (in terms of scale and offset from some point). Having a CRS assigned would facilitate the viewing several scans at once

comment Creating nanoscale DEM with GDAL
Thanks! Guess this is more a comment than an answer. As far as nanometer scale goes I'd say that whatever works is great, but a true nanoscale peojection would be the coolest. When it comes to sample data I'll have to check if there are some restrictions, but it's basically a 2 dim matrix of int16 values.
