The Extent value represents the portion of the world represented by the image, and you have provided a very large portion of the world as that extent. The size represents the size in pixels of the output image. Changing the extent will change the portion of the world covered, while changing the size will change the level of detail available (i.e. a 100x100 picture of the world would be able to show far more than a 10x10 picture, which wouldn't show much of all). You're going to want to specify that to be much, much, smaller, and somehow based around GPS coordinates or something, which for a house are going to need to be specified to many decimal places.
Also, you're going to need to georeference the input image through a similar mechanism; either through a world file or a GDAL Vrt file (or using something like GEOTiff with built in georeferencing). You might look into just having OpenLayers display the images through a vector layer of some sort (e.g. KML) and center them around a point if you just need approximate locations and aren't going for some sort of seamless mosaic. That wouldn't involve mapserver at all. Getting accurate georeferencing for aerial photos would take a fair bit of work (I think that involves lining up several GPS points?). There's an option in the Outputformat to specify transparency to fix the black issue. Hopefully that points you in the right direction, I don't know much about georeferencing images like that. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/quick-question-from-mapserver-beginner-tp5040040p5047624.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapserver-users
