It sounds like you don't want to do any pre-processing... if you change your mind you could: 1). Create a coloured overlay and place that as a translucent layer. http://openlayers.org/dev/examples/layer-opacity.html This could be a single image file, or another tile server (as per example). 2). Create a set of vector shapes (contours?) and overlay those using an OSM or other layer (could be heavy on browser if a larger area). The Srtm2Osm scripts already make the contours so these can probably be abused. Other hint: applications like Gnuplot and matlab can take single point data and export a x-by-y table of data. In gnuplot use the 'set term table' command a replot your graph If you find another way, post it here so we can all learn :-) Simon. _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
