50cm grid

Kauring, WA - 30cm imagery captured by WorldView-3 - DTMKauring, WA - 30cm imagery with 1m contours derived from a 50cm DTM grid

These DEMs will be available through the latest generation of VHR satellites such as WorldView-3. With the WorldView-3 satellite acquiring stereo data at less than 50cm resolution, DEMs will be available at lower than 1m resolution. The higher resolution DEM products will allow more precise modelling within applications such as Project Planning.
