DigitalGlobe EarthWatch – Update on the United States and Canada

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!

August 2019 Product Update

The available DigitalGlobe EarthWatch imagery over the United States and Canada 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.

Last month we checked out the coverage in a perennially cloudy region of the world and were surprised by the extent of recent imagery! For August, we pivot to the flagship region of the EarthWatch product, the United States and Canada, for a check-in. What you can see in this map is extensive coverage when you consider data 2 years or less old – but you also see the impacts of a cloudy few seasons in the Midwest and Appalachia as there are pockets of dated imagery in these regions. You can check out more of the coverage stats here:
