I am developing a Web Based GIS for location services which will allow a user to select a raster map from a list and certain category of location services. The system will then locate the location services on the raster map in the form of polygons.
So far I have successfully developed the portion mentioned above using PHP for programming and MapInfo MIF files as the source of coordinates information.
But now I need to implement a module that would take from the a user a start and end point on a map and then draw the paths (either shortest or all possible) between those two points.
I have MIF files that contain all the paths of a single map. I need help for dynamically drawing the paths between the start and end point.
