@hugoledoux project is still being worked on yes? Ok, little further. Any idea what the giant spikes can be? They appear not to come from the las file?? |
Hi @rduivenvoorde , thank you for your detailed description.

Hi,
Eager to test this as geo-people in Nieuwegein, we thought to start with a small part of the city: "galecop".
Below our experiences:
We downloaded gml, and tried to run the commands in
BGT_conversion_full_gpkg.bat
one by one.The two replacement commands in powershell ended ok, but the resulting GML was not valid anymore... in a parts of the gml,
srsDimension="2">
becamesrsDimension=" 2\>
. Not sure if this particular gml was the problem or if Windows just cannot handle suchbig
textfiles ;-)Fixed by hand, they all looked good.
Then we thought to be clever and adjust the ogr2ogr commands to ALSO clip our gml to the exact part 'galecop' by adding a galecop.shp file and putting
-clipsrc galecop.shp
in the ogr2ogr commands...That resulted in a lot of warnings and errors, probably because the clipping results in non-valid or split geometries/objects?
Is it maybe possible to do this 'clip/extract' step in your software? In that case at least the input is still valid.
The input geopackages look OK in QGIS:
But we also see some holes in the data:
Then running the final 3dfier command results in an obj and json file, but trying to open the obj file in Meshlab, it opens (with material file next to it), but only on a very large scale:
But impossible to zoom in further, as then the area disappears...
If needed, I'm happy to provide the input or output material I used. Just let me know. I'm aware that this are mostly input/data issues but thought to let you know.
The text was updated successfully, but these errors were encountered:
