Heightmaps are commonly used in geographic information systems, where they are called digital elevation models.

He created a water flow routing algorithm, which specifies how to eliminate spurious pits from digital elevation models.

It can also use DEM (digital elevation model) files, and other graphic surface maps for rendering.

In geographic information system, point clouds are one of the sources to make digital elevation model of the terrain.

Elevation data are taken from a digital elevation model.

A typical example is geographic information systems, especially digital elevation models, where the full data set easily exceeds several gigabytes or even terabytes of data.

Users convert further data (like satellite imagery and digital elevation models) from other sources and import them.

Aerial photography, land cover data, and digital elevation models all provide coverage data.

Mappers may prepare digital elevation models in a number of ways, but they frequently use remote sensing rather than direct survey data.

Sometimes the earliest data for the glacier surface profiles is from images that are used to make topographical maps and digital elevation models.
