This morning, I found a site dedicated to geospatial analysis that I thought I would pass along. It illustrates the broad range of applications that remote sensing can be used for, and how to best work with large datasets. Although postings are sporatic, it is now bookmarked as one of my "GDAL goto" sites since it offers great ideas, approaches and tips on analyzing GIS data.
The post about publishing 3D DEM's online immediately caught my attention. I have been considering displaying a 3D NVIZ DEM created in GRASS GIS online, but couldn't determine the best way to get it done; this looks like a reasonable workaround.
The posts Using GDAL with Python: a basic introduction is something that I have yet to attempt, but am looking forward to learning more about. Also there is a helpful post about Installing GDAL on Ubuntu , which admittedly, is better than my own.
Enjoy.
