Success for 90m Global DEM

PlanetObserver global Digital Elevation Model (DEM), with a 90m resolution worldwide, is successful since its launch last Automn 2010. The advantages ranging from a truly global coverage to reliable and corrected data compared to SRTM v4 product from the Shuttle Radar Topography Mission have quickly convinced many companies in different industry sectors to acquire this terrain dataset. Application markets range from geological surveys to media solutions, visualisation and simulation products and satellite imagery processing.   Companies such as the French Geological Survey BRGM, Vizrt, Eurocopter, Astrium Services, the French Space Agency CNES and GAF AG are amongst the first customers...

DEM of Iceland from Topographic Maps

East View Cartographic (EVC) (MN, USA) has completed a project to create a 30 metre Digital Elevation Model (DEM) of the Akureyri Airport in Iceland. The ability to supply DEMs derived from authoritative topographic maps fills a significant gap in worldwide DEM coverage since the widely available SRTM90 DEM data covers only about 80% of the globe. The Shuttle Radar Topography Mission (SRTM) did not collect data above 60 degrees north or below 56 degrees south latitudes and does not provide DEM data for areas such as Iceland. Topographic maps are an excellent source material for DEMs over Russia, Scandinavia,... (read more)

Aerial Solution for Geo-referenced Orthomosaics and DEM

Lehmann Aviation, manufacturer of professional micro civil drones, has announced a new aerial solution for geo-referenced orthomosaics and DEM: the LA300 fully automatic personal drone which is now working with the GoPro Hero3+ camera, in addition to the Nokia Lumia 1020. In 2013 Lehmann Aviation launched LA300, a fully automatic personal drone working with the Nokia Lumia 1020 and designed for mapping and DEM. The last months' flight tests have proven compatibility of the GoPro Hero3+ camera (in addition to the Nokia Lumia 1020 41MP camera) with the LA300 for orthomosaics and DEM which makes the drone a very suitable,...

Astrium Unveils First WorldDEM Sample Data

Astrium, the world’s second-ranking space company, has released the first WorldDEM sample datasets for evaluation purposes, enabling potential customers to begin testing data for various applications including line-of-sight analysis, 3D visualisation or orthorectfication of satellite imagery. The sample data also facilitates testing of the Digital Elevation Models (DEMs) in the users’ data management environments. After evaluating the data, users can provide feedback to Astrium Services, helping to enhance the WorldDEM offering and its services. This is an opportunity for potential customers to test the WorldDEM data and experience firsthand the remarkable level of accuracy of the WorldDEM, that will surpass... (read more)

Choosing the Best Digital Elevation Model

Canadian Force Base Gagetown
The process of achieving environmental stewardship is bound to available Digital Elevation Model (DEM) accuracy. A good DEM helps directly locate and monitor streams, sensible slopes and watersheds. Indirectly, it enables the production of orthophoto maps, intervisibility analyses and three-dimensional visualisation. In this project, three different DEMs covering Canadian Forces Base Gagetown in Atlantic Canada were tested: one DEM created from Lidar, and two DEMs generated photogrammetrically using high-resolution imagery. Comparison of data management, flexibility and software requirement confirmed the superiority of Lidar DEMs. View Larger Map Three different DEM datasets were used for this project. A Lidar DEM was... (read more)

Airbus Releases Elevation Model for Global Orthorectification

Airbus Defence and Space has expanded its WorldDEM portfolio with the launch of WorldDEM4Ortho. Tailored for orthorectification of high and very high resolution optical and radar satellite data, WorldDEM4Ortho will enable corrections of all distortions induced by the topographical variations of the Earth’s surface and satellite orientation when acquiring an image. WorldDEM4Ortho covers the Earth’s entire land surface and is one of the most consistent and accurate elevation models for orthorectification on a global scale. Without these geometrical corrections, satellite images cannot be used in Geographical Information Systems or for any mapping related applications. With the huge development of new... (read more)
