[GRASS-user] Wrangling CityGML with GRASS ?

["Peter Löwe"]

Hi Stefan,

thanks for the link: That's also the latest information we found so far, except for several OSGeo conference recordings (e.g. https://doi.org/10.5446/40913 https://doi.org/10.5446/40694).
My colleagues have ingested CityGML datasets into R, which caused issues with the vector-topology for individual buildings. Also, we have to cope with significant amounts of CityGML datasets, which would require very large amounts of RAM, if the processing is done in R. Since GRASS locations are storage-effective AND GRASS handles vector topologies well, I had hoped that someone already explored this approach further :-)

If this should be not the case (yet) we'll gladly report at one of next years FOSS4G events.

Best,
peter
