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 (GBM).

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

September 2016 Product Update

The available DigitalGlobe Basemap imagery over China by location and the most recent coverage date. In the vast majority of locations, there are multiple imagery dates available.

In our last check on GBM, we focused on Australia and this month we move to one of the most consequential countries in the world, China. And even with the persistent cloud cover over much of China and the huge competition for satellite resources along its booming East Coast, the coverage is still quite impressive. Check out the map here as well as the stats below!
