Data for Mapping a road

[HOOTSMON]

Hello,

 

Does anyone know where i could get data that would allow me to recreate a roads gradients etc. For example does google earth store this info or are the cars that take the road images fitted with other data recording tools thats available.

 

Its to recreate real roads into a game mod without going to the road itself, in this case roads on the Isle of Skye.

 

thanks

It's unlikely the cars calculate that, because it's not really useful data to the regular person. At best you can get altitude points at fixed intervals or find a topography map, and compare your work with Street View.

A car needs to have very expensive and specialized sensors for doing DEM, advanced GPS tracking and such. You can get close with open data. OpenStreetMaps have basic data which doesn't mostly have DEMs. Just XY lines. Google Earth has modeled their maps with NASA's DEM mappings.

 

I have bookmarked few sites that have open DEM files. You can get up to 30m accuracy (which might be same that Google Earth has, I don't remember). You can get higher res stuff with more digging, like 5m accuracy. But I think 30m is well enough. It means that there's elevation point every 30m.

Do note that you need GIS software or DEM modelling software to work with these. I can recommend QGIS.
