----------------- Is it possible to create or digitize online (on a webGIS created using a open server)on a satellite image for example Landsat. My aim is to create aoi's(area of interests) and it should be able to save the created layer to the database. I read that SVG can be used for this. Is it true. Can any one help me in this regard. ---------------- If I understand what you're asking, you have a bitmapped image (like .jpg or .tiff) and are wondering if you can use SVG to find regions (like polygons) within that image. Not really... not without some assistance from a human. There are software packages than can assist with the automatic recognition of simple edges and the like : Adobe Streamline, NIH Image (freeware), and Inkscape (open source), just to name a few, have differing levels of capability at "vectorizing" bitmaps. Inkscape works natively with SVG, and so it can assist in such matters. On the other hand, using SVG, one can create a web page which would allow an image (in say jpg format) to be inserted into a drawing space, where thereafter a human could zoom in and pan about, and then draw polygons atop the image (identifying crucial features). The user-created layers could then be exported to a server. Hope this helps, David Dailey [Non-text portions of this message have been removed] ----- To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ---- Yahoo!
