Forest Inventory Mapmaker Version 1.0 Internet address of your retrieval's output SessionID=657895626 If this retrieval takes more than 5 minutes your browser may timeout. Even though your browser has timed out your retrieval will continue to run. The table generated by your retrieval can be viewed at a later time by typing the following information on your browser address line: http://www.ncrs.fs.fed.us/4801/fiadb/temp2/j115115531.htm You can generate a map based on your retrieval by typing the following information on your browser address line: http://www.ncrs.fs.fed.us/scripts/esrimap.dll?name=forest_inventory_mapmaker&cmd=map&datesta mp=j1151155&
