I have a requirement to create a web based application, which is hosted on a intranet server(no internet access). This application will be used to keep track of various status over in the various geographical location, the locations are currently spanned within Asia.
I have read up on google map api, and it seems that it is against their policy to use their map offline. On the other hand, the custom markers is something that I am interested in. I am considering to make use of the marker concept to show the status of the area.
Hence sample example of the status can be denoted by having red as error, green as working properly, and this will be updated every 1 hour.
Any bros have done similar concept and will be willing to guide me? The offline maps is preferred to be free, however if a paid version proves to be useful, it can be considered.
Seems like you could use a combination of MapServer as mapping server and openstreetmap as data source (maps for asia are available, but it depends on the level of zoom, precision and update you are willing to work with) and OpenLayers to load, display and render your markers and data.
