Hi,
Take this GeoJSON
{
"type": "FeatureCollection",
"features": [{
"type": "Feature",
"id":12425552,
"properties":
{
},
"geometry": {
"type": "Point",
"coordinates": [26.30578223, 60.26170791]
}
}]
}
Ogrinfo knows the fid
OGRFeature(one_feature):12425552
Convert into a new GeoPackage and the native fid is lost
ogr2ogr -f gpkg one_feature.gpkg one_feature.json
OGRFeature(one_feature):1
Running the command with "-preserve_fid" keeps the native fid but according to
ogr2ogr documentation https://gdal.org/programs/ogr2ogr.html that should not be
needed:
"Use the FID of the source features instead of letting the output driver
automatically assign a new one (for formats that require a FID). If not in
append mode, this behavior is the default if the output driver has a FID layer
creation option, in which case the name of the source FID column will be used
and source feature IDs will be attempted to be preserved."
Is the error in the documentation or in the GeoJSON-GeoPackage conversion?
