Hi,
I am trying to make some autogen using Microsoft USBuildingFootprints using geojson files converted to shape files. I have successfully made the photoscenery tiles using this program https://github.com/stackTom/Ortho4XP_FSX_P3D and they show in P3D V5.
The program above makes tiles in a 1 degree lat x 1 degree long area. The tile in question is one with the bottom left corner at 40.0 N, -112.0 W. So the top right corner is at 41 N, -111 W. The tile includes a large part of Salt Lake city in Utah.
I looked at OSM data but it is very sparse in the USA and I can get autogen using OSM for Salt Lake City, but two thirds of the city is missing buildings.
I downloaded a geojson file for the whole state of Utah from here https://github.com/Microsoft/USBuildingFootprints and loaded it into QGIS and exported it to a shape file.
The shape file shows all the building footprints in Utah in QGIS, but the geojson file is nothing more than a heap of polygons without any attributes but we know they are all buildings.. The geojson file looks like this....
At this stage I am trying to show any autogen at all on my tile with a very, very basic script as shown below but everything I try shows no autogen.
The script (see below) creates around 2,000 agn files and I have placed them all in a texture folder in along with my scenery folder but no autogen shows. The autogen files range from 64kb down to 1 kb in size.
For the script, I have included a bounding box which is the same size as my tile as I don't need the whole of Utah.
I have used a random guid roof type as an experiment -( I have reported some issues with P3D V5 not showing guid rooftypes in this thread https://www.fsdeveloper.com/forum/threads/prepar3d-v5-support.447308/.)
Some questions:
Does the script look OK ?
Do I have the bounding box coordinates correct ?
How do I split the grid if there are no properties labelled as buildings in the shape file ?
Why do I get no autogen showing in P3D V5 ?
Do you have any suggestions on how to cater for large and small building footprints as many of the polygons are large industrial type building as well as small houses.
Also, the script below is one used successfully with OSM data from the Ortho4P3D program to create autogen for the tile, but it is very sparse...
