How to create large scale 3D terrain with open source tools?
In the simplest case we use an existing image tile server to transfer raster terrain and convert to a dense mesh on the client, just before rendering. This means every height measure in the raster becomes a vertex in the mesh. This places extra runtime demands on the client as meshes with many vertices are slow to render.

What kind of data is used in tiling?
Tiling is the current standard way to efficiently load and display web based maps. This method can be applied to both raster and vector content. For example, satellite images are stored and transferred as bitmaps. Roads and geographic geometry are typically stored as vector data.
Which is the best open source 3D mapping tool?
TIN Terrain is our new open source tool that generates TIN meshes from raster terrain. CesiumJS will load these meshes and render them on a client. Why 3D? Digital and web based maps have been stuck in 2D mode for many years, but with an ever increasing supply of good quality terrain data, there is now a race to provide 3D mapping services.
How big is an area of raster terrain?
For example, raster terrain data covering 100 square kilometres at 20cm resolution comes to roughly 20GB of data. To map an area of a typical city like Berlin would generate around 180GB of data.
Where can I get free 3D terrain data?
Fortunately the free offering is getting very comprehensive. Here is a list of some good free terrain data sources to get you started: Tiling is the current standard way to efficiently load and display web based maps. This method can be applied to both raster and vector content. For example, satellite images are stored and transferred as bitmaps.
What’s the difference between regular meshes and tins?
The difference between regular meshes and irregular meshes (TINs): the latter make more efficient use of vertices by placing them only where needed. This is where TIN’s come in: Triangulated Irregular Networks. These are meshes that contain only vertices where they define meaningful change in surface height.
