DigitalGlobe Basemap – 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 Global Basemap (GBM).

With Global Basemap, 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 GBM is the regular updates you can receive as out-dated imagery is often of little or no use to our valued clients.

December 2017 Product Update

The available DigitalGlobe Basemap 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.

In November, our focus was on +Vivid, which are countrywide (or close to it in some cases) offline mosaics produced in TIFF format; and in December, we pivot back to our normal topic with a look at the depth of the GBM database over South America. And okay, yes you are correct, the coverage is not as recent as you might find over the United States but that is not due to lack of effort! Rather, as you can appreciate, South America is a cloudy place – either way, check out the coverage statistics on the data we can offer over this region with GBM:
