Digital Surface Models
Use 3D data to produce a Digital Elevation Model, Digital Surface Model, or Digital Terrain Model (DTM), to give a visual representation of the surface of the earth and its features.
These assets are useful for areas such as infrastructural management, hydrology managing coastal erosion, archaeology, flow-direction studies, land-use and city planning, and following landslides.
Capture
We Capture RGB, thermal or multispectral images with our cameras. We can also use a drone, automate flight and image-data transfer.
Digitize
We transform these images into real time orthomosaic maps ready for your inspection and annotation.
Control
Assessing and improving the quality of your project. The quality report gives a preview of the generated results, calibration details, and many more project quality indicators.
Measure & Inspect
Measure distances, areas, and volumes. Extract elevation profile data and perform virtual inspections.
Collaborate & Share
Streamline project communication and teamwork. Selectively and securely share project data and insights with your team, clients, and suppliers.
What Is a Digital Elevation Models?
Digital Elevation Models, also known as DEMs, are a visual representation of the elevation data for every point captured on your site.
​
Instead of depicting how your site actually appears in person, DEMs generally use colour to indicate differences in elevation - as this image shows.
DEMs are raster datasets, or grids that list the highest vertical point (z) recorded for every horizontal coordinate (x,y).
​
The smaller the grid cells, the more detailed the information is within a DEM data file. So, if you’re looking to model with lots of detail, then small grid spacing (or small cell size) is the one to go for.
​
When visualised, these raster files depict the shape of your site’s terrain, which can be used as a reference for the topography you’re working on.
Quality and accuracy of DEM/DTMs
Several factors influence the quality of DEM-derived products:
-
Vertical resolution
-
Terrain roughness
-
Sampling density and resulting spatial resolution or pixel size
-
Terrain analysis algorithm
-
Interpolation algorithm
-
Reference 3D products with quality masks containing information on the coastline, snow, clouds, water bodies, etc.
Flood Inundation Models
DEMs can be used to perform many geospatial and hydrological modeling.
​
Ranging from flood prediction and the physical development of urban and rural areas to watershed delineation and flood impact analysis for emergency preparedness.
Flood inundation modeling or flood inundation mapping is required to understand the effects of flooding in a particular area and on important structures such as streets, buildings, roads, and railways.
​
Quantifying the risk of flooding through flood models predicts inundation extents. This can be a crucial source of information for flood risk studies—especially as our world warms and sea levels rise.
DEM analysis
The uses and applications of DEMs are even more varied than how they are acquired. Relevant and useful for almost any industry or sector that uses location data, some of the general uses include:
-
Slope analysis
-
Aspect analysis
-
Delineating drainage networks and catchments
-
Identifying geologic structures
-
Viewshed analysis
-
3D simulations
-
Change analysis
-
Orthorectification
-
Contour mapping
