Digital Elevation Modeling Services

Flatworld Solution's DEMs services help optimize pre-planning/planning of engineering and environmental projects.

Digital elevation models (DEM) are key components in pre-planning and planning phases of many construction and conservation projects. DEMs can be used to facilitate lay-outs of corridor surveys, seismic line locations and well sites, among others. They enable project planners, and logistics and operations managers to ensure project access is optimized for successful fulfilment of project objectives. As a collection of elevation points at regularly spaced intervals, digital elevation mapping can also highlight ridge lines, slope breaks and incised streams, as well as other abrupt changes in the surface formation. It is this regular grid spacing that differentiates a digital elevation model (DEM) from a digital terrain model (DTM), which uses irregularly spaced heights.

Flatworld's Digital Elevation Modeling Services

Flatworld generates digital elevation models in different ways, according to your requirements or constraints. The topographic information required for a DEM can be extracted using photogrammetry and image matching technology for the automated collection of mass points and break-lines. Alternatively, laser and radar-based survey techniques can be used to automatically yield digital elevation data. In particular, Flatworld handles:

  • Data overlap for the correct joining of digital elevation data and datasets (clip and merge)
  • Rectification of aerial photography and satellite imagery
  • Data format transfers, for example from SDTS (Spatial Data Transfer Standard)
  • When you outsource digital elevation mapping to us, you get our guarantee of quality, cost and deadline satisfaction

Serving Civil Engineering Teams with Digital Elevation Modeling and Related Services

While quality is always a key factor, Flatworld services are also flexible in terms of the amount of digital elevation model data used. We apply our technological and expert resources in the most cost-effective way for you. We measure the quality of DEM products and services by the accuracy of the elevation at each pixel and the morphological views. Initial factors affecting quality include terrain roughness, grid resolution/pixel size, and sampling density. Further choices include the degree of vertical resolution and interpolation and terrain analysis algorithms. We work with you to define the optimal mix that brings you the level of detail and quality you need to successfully launch and progress your projects.
