Topography and elevation (DEM)

A digital elevation model (DEM) gives your project a ground surface. With one in place, the 3D viewer drapes real terrain under your drillholes, and records that arrive without an elevation can take one from the surface automatically.

Requesting elevation data

Open the elevation page and request coverage for your project area — geoDB fetches public elevation data for the extent you choose and processes it in the background; you'll see the dataset appear in the list when it's ready. Larger areas take longer; you don't need to keep the page open.

Bringing your own

Have a better surface — a LiDAR-derived DEM or a drone survey? Upload the GeoTIFF instead. Project files accept large rasters, and the 3D viewer uses the highest-resolution surface available.

What uses it

• The 3D viewer — terrain under traces, collars and geology.
• Elevation fill-in — collars and samples imported without an elevation value can be assigned one from the surface.
• Sections and strip logs — anywhere depth meets the ground surface.

One request, early in the project, and you never think about it again.
