IMO: Thanks for the comments Michael, I was wondering if you'd contribute;-) (Also, note that wavelet does not necessarily imply lossy anymore, as many assume. Story of my life.) Can you point me to any studies to support the claim that JPEG2000 can indeed be indeed non-lossy?

- Some of the biggest advantages though, come from the corporate IT support that you come to rely on, e.g. regular backups, large disk capacity on fast SAN devices, secure access to data by authorised custodians, redundant databases for disaster recovery, point in time restoration of

All too often, the benefits touted for raster-in-database have nothing to do with the database, and everything to do with the data preparation tools that the vendor is including with their raster-in- database solution. To store rasters in a database, you need a set of tools that will (a)

IMO: Hi Paulo, I have been wondering, and haven't found much literature on the subject of applying GIS to the EP chain. I can see it would be useful, but can't exactly see where and how. Also note, that I am coming from a geology background, now working with reservoir geophysics, and

Hi Bruce, What approaches are people using with large Lidar datasets? You might take a look at the WeoGeo group. They are a commercial operation, not FOSS, but they are throwing dedicated AWS instances at the issue of lidar file serving. The dedicated instance, I gather, is for the sole

IMO 12 million records is teensy. Stuff it into PostGIS. It's the billion- point LIDAR sets that leave me queasy, but I can't begin to think of a reasonable architecture for that without learning more about how the points are actually USED, which I really am not clear on at the moment.
