DigitalGlobe EarthWatch – Download Directly From the Entire DG Archive Now!! – Update on the Middle East

Do you have the need for regularly updated images of locations around the world?

Perhaps you need imagery to integrate with an OEM solution you are developing?

Or maybe your organization uses large amounts of high-resolution imagery each year, and you are seeking a low-cost option for this data?

If you answered yes to any or all of these questions, then the solution you are looking for is DigitalGlobe’s EarthWatch (formerly called Global Basemap or GBM).

With EarthWatch, you have access to millions of square kilometers of streamed imagery with low cloud-cover and off-nadir angles. This data is accessible in web-mapping services and in an online viewer. Perhaps the most important feature of EarthWatch are the regular streaming updates you can receive as out-dated imagery is often of little or no use to our valued clients.

And if the EarthWatch streaming database lacks the coverage you need, Premium users are now able to download any image from the entire DigitalGlobe archive (minus IKONOS data) in a wide variety of formats!

May 2019 Product Update

The available DigitalGlobe EarthWatch imagery over the Middle East by location and with the most recent coverage date indicated with varying colors. In the vast majority of locations, there are multiple imagery dates available.

Without question the biggest recent news about EarthWatch is the addition of direct data downloads (Premium users only) from the entire DigitalGlobe imagery archive (minus IKONOS)! This is an exciting change, particularly for clients looking for orders well below the typical minimum of 25 square kilometers for offline GeoTIFF deliveries. Send us an email at sales@apollomapping.com if you would like to find out more about this exciting new offering!

As for our normal monthly updates, last month we checked out the EarthWatch coverage over China and Russia and this month we head to a hotspot of geopolitics, the Middle East. And okay for a region with a ton of interest, the currency of the coverage can lack in the interior but many of these areas are unpopulated. So in the places where change is happening, EarthWatch has you covered as usual! Here is a more detailed summary of the coverage statistics:
