Hi, I might succeed meeting with some ESRI / ArcGIS folks at AAG next week; I'm in touch with them in particular about linking R to ArcGIS. I would like to find out if any of you has been successful (or unsuccessful) in reading or writing ArcGIS geodatabase files directly from R, by using the rgdal driver, or by some other means.
Thanks for working on this. I have had success reading .mdb files but not .gdb files. I typically use rgdal for this sort of thing. I was under the impression that GDAL support for .gdb files started with 1.9.
This is off-topic here - the topic here is space-time data. Your question is answered with respect to Personal geodatabases on the Windows platform in thread: http://article.gmane.org/gmane.comp.lang.r.geo/13571 (link to gmane because it crosses a month boundary). You did join that thread, and said there that you are using OSX. You were able to open Pgeo files, I think. Are you thinking of the new file geodatabase format? If you read: http://www.gdal.org/ogr/drv_filegdb.html you will see that you must build GDAL linking to the proprietary FileGDB API SDK, which requires an ESRI global account. Reading the OGR format file would tell you that, no? Roger
I am very interested in this issue since I am a regular user of ArcGIS (teaching) and R (research). Michael
Another issue is reading/writing spatio-temporal features ?(netcdf does spatio-temporal grids/arrays pretty well it seems); rumours go that ArcGIS might, in the near future, support reading/writing SpatiaLite.
