WorldDEM for Civil Engineering

Successful civil engineering projects, be they large or small in scale, rely on detailed and accurate geo-information for feasibility studies, design and construction phases. WorldDEM™ supports your projects with dependable information for site assessments, project planning as well as environmental impact monitoring - even in remote areas.

WorldDEM – The DEM of choice for Civil Engineering and Infrastructure/Construction projects, when your daily business is:

  • Pipeline route profile development, planning and design in preparation of pipeline construction, powerline monitoring, landslide monitoring
  • Identification of best corridors, planning and design for road & railway, engineering surveys
  • Hydrological modelling and construction planning of new dams, assessment of environmental impact
  • Early-stage construction cost estimations and planning for infrastructure projects
  • Wind farm construction, and production monitoring

The Gariep Dam is the largest storage reservoir in South Africa. Its primary purpose is for irrigation, domestic and industrial use as well as for power generation. The wall is 88m high and has a crest length of 914m and a surface area of more than 370 square kilometres when full. The dam is on the Orange River about 48km North-East of Colesberg and 208km South of Bloemfontein.

Desktop planning and construction based on high resolution DEMs is a market for both, the small value-adding or service businesses as well as the large engineering consultancies and companies. For first surface geology assessments, WorldDEM is the ideal choice without having to send surveyors onsite. It allows for a realistic visualisation of the topography and the features of the terrain, in particular in poorly mapped areas or where topographic information is outdated. Raster analysis routines can be conducted on the data for survey planning. Digital topographic data sets like WorldDEM facilitate urban planning and enable engineers to model and plan linear constructions like roads, railway tracks, oil and gas pipelines, bridges, and electric power lines within an existing landscape context while maintaining maximum cost-efficiency and keeping the potential environmental impact of activities as low as possible.

For geological mapping, hydrological modelling or terrain analysis, you benefit from the WorldDEM DTM (Digital Terrain Model), which is derived from WorldDEM by removing vegetation and man-made objects to reveal the bare terrain of the Earth’s surface. As the DTM product is based on the high-resolution WorldDEM a uniquely high level of detail and accuracy is ensured.
