Digital Elevation Models

Detailed topographic data are essential for engineers, modelers, and planners. EOMAP’s Digital Surface Models (DSM) and Digital Terrain Models (DTM) provide this information. Enhance your coastal planning and field operations with precise DSM/DTM services.

How your DTM could look

Digital Terrain or Surface Models by EOMAP enable rapid, high-resolution mapping of coastal areas worldwide. Thanks to our satellite technology, there is no need for on-site surveys.

How we create coastal zones in 3D

Our Digital Surface and Terrain Models are built on precise elevation data and advanced algorithms. A robust processing workflow eliminates distortions from vegetation, buildings, and other surface features. – Leverage our DSM/DTM to achieve unparalleled accuracy for your geospatial needs!

Digital Surface Models (DSMs) and Digital Terrain Models (DTMs) by EOMAP offer a range of spatial resolutions from 0.5 to 5 meters. This flexibility allows for detailed and precise elevation data tailored to your specific project needs. Whether you require high-resolution data for urban planning or broader coverage for regional analysis, our DSM/DTM products provide the accuracy and clarity you need.

Enjoy the spatial resolution required for informed decision-making!

Satellite imagery enables Digital Elevation Models (DEMs) in high temporal resolution. These frequent updates provide critical insights into dynamic environments. Clients and partners use them for precise modelling of seasonal changes like vegetation growth, and erosion patterns.

Move forward with accurate, up-to-date geospatial data for informed decision-making!

Seamless topo-bathy grids strongly support coastal planning and management. We combine very-high resolution topography and very-high resolution bathymetry into these grids. All data are based on most recent satellite data or other sources on demand.

Why choose EOMAP’s DSM / DTM?

You’ll receive a feasibility assessment for your site within hours.

Typically, the absolute vertical and horizontal uncertainties are 3 m LE90/CE90.

The actual vertical accuracy is dependent on the environment. It can, for example, be influenced by the presence of tall buildings or dense vegetation. In an open environment with moderate vegetation density or rural landscapes, the expected accuracies are usually well below 2m up to 1m LE90.

Yes, orthorectified images are provided without additional cost on request.

We compare and validate DEM data with very-high resolution and recent survey data when they are accessible for parts of the site or provided by the client. Alternatively, we use our Satellite-Lidar Bathymetry profile database to quantify elevation uncertainties. Additionally, we run sensitivity models which provide estimation of the error budget of the model itself. An elevation uncertainty is provided for every point.

The default file types for our topographic data are ASCII XYZQ files (point clouds), GeoTIFFs (georeferenced raster files), KMZ overlays for Google Earth, PDF maps and contour lines (shape files). All data come with a ‘quick look’ and metadata conforming to ISO 19139. Other formats, such as ENC and CAD, are available on request.

Yes. All our deliverables conform to OGC standards and can easily be opened, visualised and analysed in any GIS.

EOMAP offers Multi-source Bathymetry Grid datasets and Digital Elevation and Surface Models. Both can be merged to a single, seamless elevation model.

You can count on precise and actual elevation data, and advanced algorithms. Via our robust technology, we avoid distortions from surface features, such as buildings or vegegation.

Moreover, our satellite-based DSM/DTMs offer a proven track record worldwide. Get in touch for relevant reference projects.
