About a week ago I wrote about OGR, but actually that library is part of a bigger one. That is the Geospatial Data Abstraction Library (GDAL). And this library offers some very nice features as well.

Let me give an example. It comes with a few tools for example and at work I used one of these to convert a scanned airport chart into a GeoTIFF image. I just told the program the latitude and longitude of a few pixel locations (threshold, airport reference point, etc). With this information the tools were able to convert my image into WGS84 projection and after that the image lined up with our runway data perfectly!

These are powerful features that can also be of use for FS scenery designers. The more I think about it, the more I think I should try to use features like this in a future tool…
