I have Two Tiger files that I need to associate. I don't know too much about the TIGER data, but have you had a look at the "edges" shapefiles. That layer seems to have everything already joined, and ready to use. So all roads appear in the edges shapefile, with their LFROMADD, LTOADD, RTOADD, RFROMADD, FULLNAME, etc, etc. You can filter out roads (or any other line features with the MTFCC column. All roads or trails start with an 'S'. Primary roads are, i.e S1100. So you could make a view in spatialite ( or a query in QGIS) showing only paved streets with: WHERE MTFCC='S1100' OR MTFCC='S1200' OR MTFCC='S1400' and so forth. I can make a query or a view in the Spatialite GUI but I don't understand how to integrate that into QGIS. QGIS can, of course, display spatialite based layers and views... Can you be more specific as to what you're trying to do? HTH, Micha
