(Data Source: DigitalGlobe) In the past month, Maxar-DigitalGlobe announced changes to the pricing of its 2 to 8-meter Advanced Elevation Series (AES) of digital elevation models (DEMs). While the changes look significant on our price list, the actual price points did not change. What did change is straight forward pricing for add-ons such as contour lines as well as a bundled digital surface model (DSM) and digital terrain model (DTM) option. Further, DEMs of the same resolution can now be delivered at a range of accuracies, allowing for high-resolution DEM creation without the need for ground control points (but also without a known absolute accuracy). If you would like a revised price list which includes the new AES pricing models or you need a hand with a DeM price quote, send us an email at [email protected] In the meantime, you can find additional information on the AES product series on our website here.

Global Advanced Elevation Series (AES)

Posted on November 4th, 2014

DigitalGlobe’s Advanced Elevation Series (AES)is a suite of elevation products that are reasonably priced with global coverage. By utilizing existing archive coverage and their constellation of 50-cm WorldView satellites, DigitalGlobe is able to offer an industry first: global elevation data delivered in reasonable time frames at competitive market prices. There are three basic product offerings within the AES: Mapping, Precision and Very High Precision elevation data. The three products are differentiated by their resolution and accuracy – this information is summarized in the table below. For each of the products, DigitalGlobe offers both a Digital Surface Model (DSM) which includes human-made and natural features (such as trees, bushes and buildings); and a Digital Terrain Model (DTM) with these features removed. Other important specifications include: Minimum Order Size 100 square kilometers Geographic Coverage Global Price lifts do exist for some Asian countries Cloud Cover 5% or less Cloudy pixels in final product are identified with an Esri polygon shapefile Data Sharing Data can be shared with up to 5 end users for no additional charge Uplifts can be applied to accommodate more end users A Summary Table of Key AES Product Specifications   Resolution Absolute Vertical Accuracy (LE90%) Relative Vertical Accuracy … testContinue reading

(Data Sources: CIGAR, ERSDAC and DigitalGlobe) Utilizing their constellation of two 50-centimeter WorldView satellites, DigitalGlobe is able to offer a global solution to a historic challenge in the geospatial world – i.e. access to high-quality, recent and reasonably priced elevation data for nearly any location on the planet. There are three product levels offered in the AES, each with differing resolutions, accuracies and price points to meet the specific needs of your project. Further, DigitalGlobe offers both a digital surface model (DSM) where human-made and natural features such as buildings, cars, trees, etc. are present in the elevation data; and a digital terrain model (DTM) where these obstructing features are removed. In this short piece, we would like to give our readers a sense of the entry level AES product – i.e. the 8-meter Mapping elevation model – and how it compares to the various sources of free data that can … testContinue reading
