Dear all, is it possible to read Geoconcept files (.gcm and .GCR) in R? ogrDrivers()$name indicates that a Geoconcept driver exists, but I was not able to read any data. I get a "Cannot open data source" error:
See: http://www.gdal.org/drv_geoconcept.html and note that it only supports *.gxt or *.txt formats. For these, try ogrListLayers() first on the file name as dsn=. Roger
ogrDrivers()[ogrDrivers()$name=="Geoconcept",]
name long_name write copy isVector 11 Geoconcept Geoconcept TRUE FALSE TRUE
list.files(path=".",pattern="nvcarte.*")
[1] "nvcarte.GCM" "nvcarte.GCR"
readOGR(dsn=".",layer="nvcarte")
Error in ogrInfo(dsn = dsn, layer = layer, encoding = encoding, use_iconv = use_iconv, : Cannot open data source Did anyone successfully use this driver? What is the syntax? Thank you for your help, Jean-Luc Dupouey
