DigitalGlobe Basemap – A Worldwide Imagery Solution – Focus on Canada and the United States

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.

October 2017 Product Update

The available DigitalGlobe Basemap imagery over Canada and the United States 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 our focus was on Asia, and in October we move to the ‘flagship’ region for DigitalGlobe’s GBM subscription service. Currently, we see that the cloudy past few months over the eastern half of the United States has limited the amount of coverage less than one year old you would normally expect to find here. We fully expect the less than one year old coverage to increase rapidly as fall moves forward. You can check out the rest of the GBM coverage statistics for this region here:
