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)

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...

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,...

An IFSAR Quality Management System

Meeting DEM and Ortho-imagery Specifications
Interferometric Synthetic Aperture Radar (IFSAR) is emerging as a highly cost-effective 3D mapping technology. Digital elevation models and ortho-rectified radar imagery are core commercial Intermap Technologies products using its airborne IFSAR based STAR technology, the list of applications for which is continually growing. Quality control and assurance ensure consistent data quality. Data quality has become a matter of escalating interest amongst the geospatial community. Data providers must thus ensure their data products meet specifications; quality must be built into the production process so that data consistently and predictably meets expectations. A rigorous Quality Management System (QMS) needs to be designed... (read more)

Mapping an Oil Pipeline

DEMs and Ortho-imagery for Colombia from Dual-band Side-looking Radar
Adverse weather and terrain conditions meant the Cano-Limon oil pipeline in Colombia had never been accurately mapped until orthorectified images and digital elevation models covering an area of 94,000km2 were created using airborne dual-band interferometric IFSAR simultaneously acquired X and P-band data. The authors report on main aspects of the project. The Cano-Limon oil pipeline extends nearly 780km from the Cano-Limon oilfield in Colombia’s Arauca region along the north-western border with Venezuela to a port in Covenas. When fully operational the pipeline can carry up to 20% of Colombian petroleum production, a major source of national revenue. In collaboration with... (read more)

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)

SimActive for European Union Satellite Centre

The European Union Satellite Centre (EUSC) has purchased SimActive's Correlator3D product for deriving accurate digital elevation models (DEM). The EUSC aims to obtain fast DEM extraction and a significant reduction in DEM editing over current processes, while preserving high accuracy as the chief requirement.   Through the use of Correlator3D, the EUSC is to benefit from the world's only GPU enabled autocorrelation engine, advanced DTM extraction module and powerful DEM editing tools, thereby saving time and reducing costs, according to Dr. Philippe Simard, president of SimActive. "This provides the EUSC with the necessary tools it requires to produce accurate and... (read more)

Optech Upgrades ALTM-NAV

Optech Incorporated (Canada) has upgraded ALTM-NAV integrated mission planning, navigation, and operations software through the incorporation of underlying digital elevation models (DEM). With this upgrade, ALTM-NAV users will be able to plan airborne missions more effectively and efficiently using ancillary DEM information from a variety of sources. Since mission success is often gauged by the ability to collect complete data in the most efficient manner possible, an underlying DEM will enable planners to be aware of topographical changes that may affect swath widths and resultant planned flight line overlaps. Similarly, real-time projection of the lidar data onto the underlying DEM... (read more)
