WorldView Elevation Suite
For successful exploration, engineering, land management, and simulation
The new WorldView Elevation Suite provides a full perspective for your project area, bundling a highly accurate digital elevation model derived from a WorldView-1 or WorldView-2 stereo pair with ortho-imagery and contours
Accurate elevation models are key building blocks for successful exploration, engineering, land management, and simulation. DigitalGlobe has partnered withPhotoSat Information Ltd. to produce elevation datasets over rural areas of low vegetation using an inno vative geophysical technology similar to 3D seismic processing that provides unprecedented accuracy from a satellite-based DEM.

|
Engineering-Grade Accuracy from Space |
| Global Reach Obtain elevation models for any country in the world without local access challenges, such as permitting or in-country presence. Our worldwide reach allows 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. |
| Current Information Conduct your operations with recent data. We will work with you to obtain the data within your date speci fications to ensure it is as relevant as possible. Utilize our custom tasking capabilities or select imagery from our ImageLibrary. |
