Thanks,
Now I found the driver in the current rgdal version!
Unfortunately I still can't open the database, even though the OpenfileGDB
driver is used.
When I list the layers
and then try to load one of the layers, I get the error message that no
features are found:
ogrListLayers("Stoy.gdb")
[1] "veg_storbyomrader" "veg_traffikert_veg"
"flyplass_store_flyplasser" "bane_storbyomrader"
[5] "bane_traffikert_bane"
attr(,"driver")
[1] "OpenFileGDB"
attr(,"nlayers")
[1] 5
> m = readOGR("Stoy.gdb",layer = "veg_storbyomrader")
Error in readOGR("Stoy.gdb", layer = "veg_storbyomrader") :
no features found
In addition: Warning message:
In ogrFIDs(dsn = dsn, layer = layer) : no features found
Is this likely due to the database, or could this be a problem with the
driver?
In case that helps, here is the link to the map layer I want to extrac (the
link is to a web page, but I have the data base file).
http://www.miljostatus.no/kart/?lang=no&extent=152517|6532562|210570|6557188&layers=147:46;20:100;138:100;&basemap=KART&opacity=71&saturation=90
