High resolution models of elevations are used in a variety of areas from urban planning to flood simulation.
(The product of our partner, DigitalGlobe Advanced Elevation Series (AES), enables one to create digital terrain models (DTMs) and digital surface models (DSM) for geological exploration, engineering, land management and simulation. AES provides the user with an access to specialized models directly from their computer and supports a variety of configuration parameters, including accuracy, resolution, type and format.
Features, Benefits and Options
Focus on Core Business Functions. With the Advanced Elevation Series, there's no need for specialized hardware, software, or staffing expertise to create and process elevation models, allowing more time for users to focus on core business functions.
Global access. Now our customers can use global elevation data without local challenges, such as permitting or in-country presence. DigitalGlobe's worldwide reach enables more efficient mapping of areas where getting a plane in the air or a team on the ground is too costly, time consuming, or unsafe.
One Stop Shop. Combining DigitalGlobe's Advanced Ortho imagery with the Advanced Elevation Series products gives users high stability in data quality and accuracy.
Optional Processing. DigitalGlobe offers several options of additional processing to enhance the Advanced Elevation Series data. Whether it is hydro enforcement, road flattening, contours or shaded relief, users can benefit from all of the additional processing their project requires.
