Satellite Elevation Data - Verified Accurate

DigitalGlobe, a leading global provider of commercial high-resolution world-imagery products and services for defense and intelligence, civil government, and commercial customers, today announced that the elevation data gathered from its latest high-resolution satellite, WorldView-2, has been verified as accurate within 30 centimeters by PhotoSat based on data collected by MWH Geo-Surveys.

To conduct the test, PhotoSat constructed an elevation grid using automatic geophysical processing of 50-centimeter ground resolution stereo satellite images taken by DigitalGlobe's WorldView-2 satellite. The resulting elevations were then referenced against more than 20,000 gravity survey stations which had previously been established as being accurate to better than two centimeters.

"As one of the most technologically advanced high-resolution commercial satellites in orbit, WorldView-2 continues to hit all of our planned milestones, and we are thrilled with the assessments made by PhotoSat," said Walter Scott, Founder and CTO of DigitalGlobe. "For our customers, the quality of the image is only half the story. Equally important is the data the image represents. Having WorldView-2's elevation data verified as accurate to this degree enables our customers to make decisions more confidently than ever before."

"We are delighted with the quality of the imagery from this new satellite and are amazed by its massive collection capacity. WorldView-2 will enable PhotoSat to provide timely elevation mapping to our resource customers everywhere in the world," said Gerry Mitchell, President of PhotoSat.
