I looked myself for a native product for Zope (Python inside) which would be GIS enabled, but didn't find. Maybe one day I'll try develop one :)). But you still have a big resource links here, where you can find something youi're looking for. http://www.spatialhydrology.com/freedownload.html. Maybe you have more time then me. I found also some links of people intending to develop a zope poduct, but is still just poetry :)). If you want an really GIS enabled website, try Apache:theotherport for cgi-bin/MapServer.... --ugly but working (see a demo at 'http://www.retezat.ro/retezatmap/index.html') I'm designing also a similar solution. If you want just some rasters interlaced with points, try MapIt (www.mapit.de)... not GIS, nut you can simulate one :(. Images have to be stored also as resampled files for zoom in&out :((. Heard about Grass+Grasslinks+PHP (), but you have to be a GIS Grass enabled user look @ http://www.geog.uni-hannover.de/grass/grass_addons.html You can search java- based solutions, I cannot help mach here, sorry. Maybe we'll keep i touch for some developements in the future, Dragos Lipan Piatra Craiului National Park str. Raului 27, 2223 Zarnesti, Brasov, Romania dlipan@pcrai.ro tel. 40-93-330477 =8-)
