The WorldDEM DTM is derived from the WorldDEM product (Digital Surface Model) by removing all man-made features and vegetation. The unrivaled quality of the original WorldDEM product combined with a sophisticated editing process guarantees highly precise and consistent terrain information. While surface features (e.g. built-up areas, vegetation) are reliably removed, characteristic terrain features such as ridge lines or mountain crests are preserved.
- Digital Terrain Models (DTMs) based on WorldDEM are now commercially available
- WorldDEM DTM can be delivered for over 90 Million km² of the Earth’s landmass
The WorldDEM DTM provides an excellent foundation layer for a wide range of applications such as civil engineering (e.g. road design, Earth work calculation), the management of natural resources (e.g. flood modeling), mapping (e.g. derivation of contour lines) as well as military mission planning (e.g. vehicle traffic-ability analysis, 3D terrain visualization).
WorldDEM is based on data acquired by the high-resolution radar satellites TerraSAR-X and TanDEM-X, which started synchronous data acquisition in December 2010 and completed coverage of the Earth’s entire landmass twice over in mid-2013. The satellites covered more complex terrain areas with a third and fourth acquisition campaign to ensure consistent high quality and accuracy of the final product. WorldDEM provides the first global, single-source, high-precision Digital Surface Model and has established a new standard of global elevation models./P>

GeoJot allows iPhone and iPad 2 users to enter attribute descriptions and attach them to photographs as they are taken. In addition, the application geotags photos with GPS coordinates that are more accurate than is standard for these devices. Photos acquired with GeoJot must be emailed or downloaded to a personal computer running GPS-Photo Link to access the enhanced accuracy and attribute information outside of the iPhone/iPad platform.
“We developed GeoJot so that people can use devices they already own for field data collection in photo-mapping applications,” said GeoSpatial Experts CEO Rick Bobbitt. “Photo mapping is a fast and accurate means of collecting location-based information for business applications that require precise photographic documentation of objects and features at a specific place and time.”
GeoJot lets the user collect attribute information about each photograph. The user can either key in 24 customized descriptions up to 100 characters in length, or the user can set up drop-down menus of feature names, values and standardized condition descriptions that can be selected as each photo is taken. These lists can be saved and shared with other iPhone or iPad 2 users.

“GeoEye is excited about partnering with Terra Pixel Corporation,” said Tara Byrnes, partner channel manager at GeoEye. "ImagePatch is a great online tool that helps customers determine their imagery acquisition needs. We believe that ImagePatch will provide a good conduit for customers that need large area satellite imagery coverage in addition to satisfying the need for smaller, local area collections."
ImagePatch provides the means to define an area of interest via an interactive web interface and choose the resolution and imagery format that you would like to receive. The addition of GeoEye’s one-meter imagery increases the custom-ordering function of the ImagePatch site, allowing users to select ortho imagery at 3, 6, 12 inch/pixel and 1 meter/pixel resolution in the format of their choosing. Formats include the recently added KMZ format for Google Earth users, and the YUM format for Virtual Earth users.
“We are pleased to partner with the leading commercial satellite company in the world,” said Rony Ledany co-founder of Terra Pixel Corporation. “Our initial goal was to provide an easy way to order imagery online, and now in a few short months, we have expanded this service worldwide.”
ImagePatch is targeted at CAD/GIS professionals that need to update specific project areas, real estate professionals and land developers that need to manage their portfolios, and local governments that want to save money by updating newly developed areas rather than flying the entire area every year.
Terra Pixel Corporation operates their own aircraft in the northeast United States, and taps into a network of professional aerial providers, guaranteeing custom imagery delivery within 30 days nationwide. The imagery imports seamlessly as an image base layer for drawings or for upload on Web-based mapping sites, such as Image Connect, Microsoft Virtual Earth, Google Earth, Leica Titan and Skyline Globe.

Save the Elephants was founded by zoologist Dr. Iain Douglas-Hamilton in 1993 and is a non-governmental charitable organization located in Kenya. The STE pioneered the use of GSM-GPS tracking collars that record and report an elephant’s position every hour. As such, the STE has a database with over one million recorded elephant positions, and has compiled incredible ranging behaviour not previously observed. The data has provided an unprecedented look at the ranging behaviour of elephants in Kenya, South Africa and Mali.
“We (STE) are using Geomatica 10 to classify multi-spectral imagery to look at land use and vegetation types in relation to elephant movements across varied and mosaicked landscapes. High-resolution aerial photos and satellite imagery are being used to map the presence of human settlements in the range of the elephants in both Mali and Kenya,” said Jake Wall, Research Scientist at Save the Elephants. “We are also using the Geomatica radar tools to experiment with using radar imagery for mapping livestock corridors in areas vital to the survival of the desert elephants of Mali. Using a wide variety of data inputs we can model and eventually understand the behaviour and spatial needs of elephants.”

Location-based services is shaping up to be a significant portion of the mobile industry going forward. While Apple has traditionally not been very strong here, the company is quietly making gains and could even surpass Google in one quickly growing area: indoor location.
Apple Maps was considered a major misstep after its launch last year was met with numerous customer complaints. Fast forward a year, and Apple Maps has gained 35 million users but, even more importantly, the company has introduced iBeacon and acquired WiFiSLAM, pointing to a major focus on indoor location.
“Google has interior mapping technology already built into Google Maps – that’s a place where they are still ahead of Apple, but I think that lead may not last long especially since Apple seems to have a plan about where they want to go, and it’s less obvious on the Google side what their plans is,” said Carl Howe, vice president of research at Yankee Group, Boston.
