MapServer can do this via Templates. We use it in our GISmo (GeoMoose) interface quite a bit for Popups.
you can see it action here: http://gis.ci.stpaul.mn.us/gis/gismo_public/html/ Just zoom in a ways, a couple of blocks, turn on the Address Point layer, and then switch to the "Visible Layers" tab, and make the Address layer imagemap active, it should be highlighted in Blue in the right hand control panel if you have zoomed in enough on the map. Just toggle it on and mouse over the Address Points. If you want the technical peak at things, here is the imagemap output call from Mapserver (that GeoMoose builds): http://gis.ci.stpaul.mn.us/datasets/DB/SAINT_PAUL/PUBLIC_WORKS/ADDRESS/STAMP-active_public.map?mapext=587340.1267982177%20162002.83410579615%20588032.8548504771%20162477.73387889678&mapsize=1218%20835&mode=nquery&searchmap=true The above link generates a Imagemap (only) fragment for use by GeoMoose. MapServer builds it based on Templates, as described in the MapServer docs in someone else's reply. bobb >>> Alexandre Leroux <[email protected]> 01/05/09 3:07 PM >>> Hi list, A rather technical question. I was able to find a potential solution with GRASS GIS, but want to know if there are other solutions involving FOSS4G software. Which other FOSS4G software can generate html clickable image maps out of polygons? The challenge is simple: a colleague has many polygons that must be exported to several clickable PNGs like the example on this page: http://www.weatheroffice.gc.ca/warnings/sqc_e.html (A webmap tool such as OpenLayers would be much more powerful, but in some cases we do need clickable PNGs.) I found out it seems GRASS GIS 6.3+ can do it via its HTMLMAP driver: http://www.phygeo.uni-hannover.de/grass/grass63/manuals/html63_user/htmlmapdriver.html Can any other OSGeo software do the same? Thanks for any reply! Alex -- Alexandre Leroux, M.Sc., Ing.
