DigitalGlobe EarthWatch – A Worldwide Imagery Solution – Focus 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 imagery with low cloud-cover and off-nadir angles. This data is accessible in streaming web-mapping services as well as through an online viewer. And perhaps the most important feature of EarthWatch is the regular updates you can receive as out-dated imagery is often of little or no use to our valued clients.

October 2018 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.

Last month we checked out the coverage over our flagship region of the United States (plus Canada), and for October we pivot to look at our southern neighbors in South America. And, okay, the coverage is not as complete for this region but if you look at the coverage within the past two years, it is near complete; and that is amazing with the sort of cloud cover we see in the Amazon. Here are the coverage stats to review as well:
