Hi,All！ I want to design a new system to display satellite images through web-gis which based on mapserver. In the old version i use oracle spatial to handle the geospatial operations,such as such as overlap of two polygons. and use php/mapscript to search Oracle spatial . Now,i want to use a new method to handle the geospatial opetations. Does PostGIS,MapInfo or GML(Geography Markup Language) can work for this function? or other database system can work for this function based on mapserver as Oracle Spatial do? Does php/mapscript can work with PostGIS, MapInfo etc?？
Anyone give me some suggestion? Any information will be appreciated thanks a million! feigle
