is there any offline map libraries that can be used f开发者_如何学Gorom PHP? I want to make an application which displays all data position of stations (with latitude and longitude) on a map.
But the user doesn't want this application connect to internet, so I can't use Google Maps as a solution. Do you know any offline map libraries that can mark position based latitute and longitude information?
Thanks in advance
If you need to render graphical maps of anywhere on the globe, you're gonna need a lot of geographical data and a lot of storage (unless you're keeping the resolution low). For geographical data of the U.S., you can purchase bulk data sets (or obtain smaller free data sets) from certain commercial organizations, or try GeoData.gov.
Once you've obtained your GIS data set, you can use Image_GIS to visualize the data. I haven't used the library, so I don't know how the results look, but that's one solution.
