I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Display terrain (elevation, geometric height, DTM): mountains, etc.

    Visualize 3D terrain instead of the sphere only.

    Note: this involves preparing and hosting of a separate tileset which will represent the geometric height by the values of pixels (greyscale). Triangles in the WebGL Earth can be then adjusted by the relevant height (pixel value) loaded from the texture (tile) at given lat/lon position.

    Possible datasets to use:
    - GTOPO30: global digital elevation model (DEM) ~ 1km x 1km - http://eros.usgs.gov/#/Find_Data/Products_and_Data_Available/gtopo30_info
    - SRTM3: Shuttle Radar Topography Mission ~ 90m x 90m - http://www2.jpl.nasa.gov/srtm/
    - CGIAR: 90m
