Digital Elevation Model WA

Posted on 15 May, 2022 by Micheal Alexander

A Digital Elevation Model (DEM) is a raster data set that describes the terrain elevation of the survey area. A terrain-following drone can collect highly accurate data about the topography of the survey area. This raw data can then, in turn, be used to create a detailed 3D raster dataset of the survey area elevations. We can apply a number of post-processing techniques to enhance the DEM, depending on what you want to use it for, providing many ways to visualize the elevation of the features of the terrain.

Precise & Accurate

We capture the raw aerial data by using professional, survey-grade drones. Standard ground sample distance (GSD) of 2.4 cm/px at a flight attitude of 120m; higher resolutions are available. Absolute horizontal accuracy down to 1 cm if required by specification. Mapping Services Albany

Post-Processing

Depending on your needs, we can apply a number of post-processing techniques to further enhance the DEM.

Standardised Formats

We can provide deliverables in most standard file formats such as GeoTIFF. We can also process the data and use it in the productions plans and reports for more complex applications.
