Hi Robert Why don't you calculate a new mapext dynamically and then substitute that?
Regards Robert Sanson >>> "Burgholzer, Robert (DEQ)" <[email protected]> 17/01/2014 >>> 11:50 a.m. >>> Hello, I am trying to get my maps to dynamically Zoom out from a location via a CGI call with URL variables. I am using mapserver 6.2, and calling in MODE=MAP since I am embedding the call in some HTML, I don't know if that matters. I am also giving a MAPEXT, but what I would like is to have it ZOOM out from that MAPEXT a bit. I have tried the URL parameters: ZOOM, and the combo of ZOOMOUT/ZOOMDIR - all seem to have no success. I have also tried SCALEDENOM and my map dissapears (values between 2400 - 24000 - 240000) - I confess that my topography knowledge is lacking there. Any help would be appreciated - below are functioning URLs (but they don't scale). Examples (ZOOM=-1): http://deq2.bse.vt.edu/cgi-bin/mapserv?map=/var/www/html/mapserv/drupal_wsp_data.map&layers=model_elements&layers=coverage_system_scaled&mode=map&mapext=-83.6754%2036.4698%20-81.2611%2037.2408&MAPSIZE=480%20320&nid=184694&zoom=-1 Examples (ZOOMSIZE=-1&ZOOMDIR=0): http://deq2.bse.vt.edu/cgi-bin/mapserv?map=/var/www/html/mapserv/drupal_wsp_data.map&layers=model_elements&layers=coverage_system_scaled&mode=map&mapext=-83.6754%2036.4698%20-81.2611%2037.2408&MAPSIZE=480%20320&nid=184694&; ZOOMSIZE=-1&ZOOMDIR=0 Robert Burgholzer Surface Water Modeler Virginia DEQ Office of Surface and Ground Water Supply 804-869-3066 This email and any attachments are confidential and intended solely for the addressee(s).
