I blogged a while back about the Open Topography portal. It’s worth taking a looking back at their mission statement:
“to build an online system that provides integrated access to high-resolution topographic data, web-based processing tools, and enables the user community to share knowledge, experiences and resources”
For those interested in software tools they provide software for point cloud visualisation and DEM generation.
Open Topography have recently received funding for the NASA LiDAR Access System (NLAS); over the course of the project they will be developing software to serve laser altimetry data from the NASA space-based ICESat system and the airborne LVIS platform. Worth keeping an eye on.
