We have raster data which is generated from (vertical) walls. We would like to keep this data in a postgis database and have the spatial reference encoded "the most accurate way". Currently, they are saved by abusing a metric CRS and encode the z coordinate of the wall as x, and the offset from...

when viewing rotated rasters in QGIS - the overall raster is rotated (as designed), though each grid cell is not. (the nodata value doesn't appear to pick up as the default in QGIS either - -2.9999e+30 instead of -3e+30, but that might be a separate question). . and a closeup is this...

I am looking for a way to collect data on the height profile of some cities over time. I don't need to produce a detailed 3D reconstruction of cities, nor do I need to detect and measure individual buildings. I would simply need a coarse proxy of how "vertical" a city is - for instance, average...

What is in your opinion the best open source development stack for creating a website which includes mapping applications in it? I am aiming here to get an answer like LAMP (List of Apache-MySQL-PHP), which is a common open source set of tools/languages for creating a typical webpage...

I finally (albeit reluctantly) made the switch from a personal geodatabase (pGDB) to a file geodatabse (fGDB) not too long ago. The main reason it took so long to switch has to do with how Select by Attributes deals with string functions. For example, I used to be able to easily select all...
