Global Basemap – A Worldwide Imagery Solution – Focus on Sub-Saharan Africa

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

Response times with any streaming service can be a challenge especially for international users. Recognizing this barrier, DigitalGlobe has now cached every GBM tile in the cloud on approximately 140,000 servers in more than 80 countries. Since hosting the GBM tiles in the cloud, global users have reported significant improvements in service speeds across all delivery platforms, with an 80% average increase in performance!
