DigitalGlobe EarthWatch – Update on South America

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 in a wide variety of formats!

September 2019 Product Update

The available DigitalGlobe EarthWatch imagery over South America 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.

During August we checked out the EarthWatch coverage in the product’s flagship regions of the USA and Canada, and for this first unofficial month of fall we pivot to our southern neighbors with a look at the EarthWatch coverage over South America. And okay South America is a cloudy place so you cannot expect the best coverage over the Amazon, but along the coasts and mountains you will see tons of recent coverage.
