I'm hoping somebody may be able to help or at least point me in the right direction, with a GIS/Mapping query that is a little unusual.
I have been tasked at work with looking at how we create a Google Maps style system for our internal roadway system - this roadway covers around 45 miles and the level of detail exceeds that supplied by any available mapping data (OS, Google Maps, OSM) source. I've looked at most the available data and its sources and its just not an option - therefore we need to have maps drawn/created to our specific requirements, which may seem OTT, but its the only way. Also this is not detail that can be done as an overlay on existing map data, the 'bosses' have already ruled that option out.
I've searched extensively on the net and can find numerous options for overlaying additional information on existing data, but nothing on how maps can be drawn and rendered, then tiled and displayed. Leafletjs solves the latter issue re-displaying, but can anyone point me to software that can create maps, link specific points to GPS co-ordinates, and export the whole thing through tiles etc..?
Are maps drawn for this purpose, or do you start with a GPS 'track' of the roadway and covert it/update/render it to a map?
I'd welcome any thoughts/suggestions as to how the project could proceed as its not my field of expertise. Help!
