Re: [Qgis-user] QGIS for safe organization use.

A more germane point to our Canadian friend’s query is the fact that the U.S. NGA, the National Geospatial-Intelligence Agency, went completely Open Source back in 2017 due to the fact that ESRI would not allow them to view the source code to check for trap doors, etc. They had been a very

Re: [Qgis-user] QGIS and historical battle

Hi Ciprian. There are many examples of such historical/archaeological research. I would suggest that you get a decent DEM (and generate slope and aspect) and vector hydrology, as Bernd suggested, but I think the most important will be to find a series of historical maps of the area. Scan

Dear colleagues, As we move more into the world of big data, IOE, data mining, and data analytics, dealing with larger and larger data sets will become required, and, eventually, the norm. GRASS GIS has made very good progress in this regard, optimizing the code to run on massively parallel
