I would like to import a Geography Markup Language (GML) file into GMAP. I know that the United States Bureau of Census (USBC) – TIGER/GML is using this format. So I do hope SAS and GMAP can access the files I need but I can’t find any information or literature on the help files related to GML format. Can some one help me or indicate me where to go from here.
I beleive the United States Bureau of Census (USBC) can import GML files and convert them into TIGER. The information links you gave me provide information reading TIGER files with the SAS/GIS. I do not have the GIS software no my computer. I am trying to see if GMAP could be use with that file.
I know it's not the same. I could not find any hits on GML and SAS.
However, it is possible to read an XML file with SAS -- so you might be able to read your GML file into a SAS dataset and then use that dataset with PROC GMAP. But PROC GMAP is meant to deal with a SAS dataset and with the maps contained in the SAS/Graph maps catalog.
So, even if you could read the XML file with SAS, that still leaves you with the issue of whether the GML coordinates correspond to the coordinates in the SAS/Graph map datasets used by PROC GMAP.
