thoughts on combining 3 regional maps into one?<br> </font> </div> <div class="y_msg_container"><br>Hi all,<br><br>I have 3 regional mapfiles for US, Canada and Mexico and I want to <br>create a single North America map. Since the data comes from separate <br>vendors and they refresh on different cycles, I'm trying to figure out <br>the best way to structure this in a mapfile. I also need to maintain <br>each region as a separate mapfile. (I'm ignoring issues like data <br>alignment over borders.)<br><br>The reginal mapfile data is structure like:<br><br>.../us/data/<shapefiles><br>.../us/us.map<br>.../mx/data/<shapefiles><br>.../mx/mx.map<br>.../ca/data/<shapefiles><br>.../ca/ca.map<br><br>The shapepath for each mapfile is set to the local data directory. What <br>I would like to avoid is having to change all the paths in the mapfiles <br>to accomodate a change
like:<br><br>.../na/us/data/<br>.../na/mx/data/<br>.../na/ca/data/<br>.../na/na.map<br><br>It would be cool if I can change the shapepath in the middle of the <br>mapfile so layers beyond the change would use the new shapepath, but I <br>suspect that will not work.<br><br>So it looks like my options are:<br><br>1. rewrite all the mapfile data pathes as I combine them into one new <br>mapfile and maintain two copies, regional and na versions.<br><br>2. maybe create a new mapfile that loads each of the regions as a WMS <br>client and overlays the adjacent regions. This will get served via <br>mapcache so that might add some options for tile assembly.<br><br>3. other ideas????<br><br>This can be done with postgis!!!<br>create a database with all layers you have, then create views joining the similar layers, and in your map<br><br>LAYER<br> NAME "states"<br> STATUS ON<br> DATA "the_geom from (select *
