----------------------------Original message---------------------------- Hello - I have downloaded 1:100,000 usgs LULC (landuse) layers. I am not sure yet what year's data these are or if other years are available. Has anyone had experience with these maps and also know the availabililty (over the internet hopefully) of same? I'm looking for several layers within the period 1960 through 1990 of Santa Clara County. thnx Mike Meuser
