DigitalGlobe Basemap – A Worldwide Imagery Solution – Focus on China

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 Basemap (DGB).

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

DigitalGlobe Basemap is a constantly evolving product and as proof of this, in March, its name was changed from Global Basemap to DGB. Now, here are some statistics about the imagery updates that occurred in the last month to the DGB database:
