Can someone please confirm a detail about the naming convention for the geographic attribute files?
According to the Road Network File Reference Guide, rgf stands for "Road network and geographic attribute file". But when I look at the geospatial files in ArcInfo directory on the FTP site, I see rnf or rngaf files. I'm assuming that rngaf stands for something like "road network and geographic attribute files", but since this seems slightly different from what the guide says, I'm a bit unsure ...
The Geographic Attribute File (92-151-XBB, see http://www.statcan.gc.ca/bsolc/olc-cel/olc-cel?catno=92-151-X&lang=eng) is available on the DLI FTP site under: /DissFTP/dli/Geography-Géographie/2006/geo-data-products_produits-de-donnees/gaf_fag/
The Road Network and Geographic Attribute File (92-155-XWE, see http://www.statcan.gc.ca/bsolc/olc-cel/olc-cel?lang=eng&catno=92-155-X) is a different product which is housed under DissFTP/dli/Geography-Géographie/2006/spatial-info_dinfo-spatiale/arcinfo/rngaf_frrag/
Table B.1 File name and sizes - 2006 Road Network and Geographic Attribute File of the Road Network and Geographic Attribute File, Reference Guide (http://geodepot.statcan.gc.ca/2006/180506051805140305/06180505162102/92-155-072305/2006001/200102120519/2001021205021-eng.htm) describes the names of the files in this product (ex. grgf000r06a_e.zip). These file names seem to match the ones for the Road Network and Geographic Attribute File product on the DLI FTP site (DissFTP/dli/Geography-Géographie/2006/spatial-info_dinfo-spatiale/arcinfo/rngaf_frrag/)
If your user is looking for the Road Network File (92-500-XWE, see http://www.statcan.gc.ca/bsolc/olc-cel/olc-cel?lang=eng&catno=92-500-XWE), this can be downloaded from the DLI FTP site under DissFTP/dli/Geography-Géographie/2006/spatial-info_dinfo-spatiale/arcinfo/rnf-frr/
I hope that this information is helpful. Please don't hesitate to contact me if you have any other questions.
