Are you really working with actual map coordinates that include longitude and latitude?
This seems to be a reverse approach to what I usually see. From what I've seen, you typically display a map of the united states. Click a state to zoom in. Have the state map divided into sections, click the section to zoom. And just continue having maps divided into sections that the user can click to zoom in closer and closer. Using coordinates to accomplish this seems possible, but overly complex. You'll literally be creating a 3D world and that means you'll end up having to create coordinate systems for every single object in the world. For example, say you give coordinates and then have a 5 mile by 5 mile map display centering on these coordinates. Then each house falling within that geographic boundry gets displayed on the map. Obviously, it sounds very cool... but incredibly complex. It's just as easy to use the method I described above to zero in on the geographic area and list houses within that zone rather than draw pin-points on a map to show where the houses reside geographically. Especially when that geographic representation includes things like other houses, streams, schools, etc. My $.10 -----Original Message----- From: Lowell Allen [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 11, 2002 1:42 PM To: PHP Subject: [PHP] PHP and geographic maps A client wants a database-driven site that records information about real estate properties and includes geographic maps of property locations (throughout the US). The client has seen a presentation of a JavaScript-powered, Windows-only product that doesn't seem to fit well with my preference for PHP/MySQL. I've been Google-searching info on GIS and GPS and GMT, but thought it might be worthwhile to ask this discussion list for input. Can anyone direct me to info on PHP presentation of geographic maps -- tied to a database with locating coordinates?
