2D &3D Terrain & Elevation Models
Drones lend themselves very well to the collection of high-quality data for terrain and elevation models. Our experts not only perform aerial surveys of open-cast mining systems, dumps, roads and other surfaces with drones but are also able to analyse the data collected and produce two-dimensional or three-dimensional terrain models or elevation models according to the customer’s preference. Terrain and elevation models are suitable among others for hydrological modelling, calculations as regards surface or volume and other applications, for example, in the fields of town planning and the construction of landscapes and roads.
CREATION OF 3D TERRAIN MODELS WITH DRONES
The experts at L.A WWIC.Ltd is responsible for planning and managing projects in the field of geographical information, the aerial surveying of terrain and the creation of aerial photographs and two- and three-dimensional terrain or elevation models with the appropriate GIS software.
DISADVANTAGES ASSOCIATED WITH TERRESTRIAL SURVEYS
Terrestrial measurements via a tachymeter to create 3D terrain models are time-consuming and often lead to results with a low information density and an increased inaccuracy potential due to a coarsely meshed grid image recording. In addition, the time needed to complete terrestrial surveys results in comparatively high costs. 3D terrain models are, however, well suited to implement, for example, hydrological modelling, calculations as regards surface and volume, and many other applications based on topographical data
