We are in need of US highway data. We found it for Florida at the state GIS website . We downloaded the data for Florida highway intersections from here (this is a zip file) . We do not know how to use these files and extract the geocode values of the intersections (exits) from these files. Any help is greatly appreciated.
Among many other options, you could open the files with the free software package saga gis: www.saga-gis.org
If you use modules\shapes\add coordinates to points you will get a table with all the xy locations and their attributes.
in arcmap 10
1) do a query on the features you would like to select and export them to a new layer (using selection - on the top; select by attributes)
2) enable the arctoolbox (by going to the geoprocessing menu on the top)
3) open the geocoding tools
4) use the geocode addresses to create the export file you need - if that is not what you want; try to take a look at the data management toolbox and see if you can find one that suits your needs.
