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.

March 2016 Product Update

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

Each month, DigitalGlobe adds new imagery to the GBM database, and our goal is to keep our readers updated on key regions of the world where this activity focuses. China is one of the world’s most important countries and is hence our focus this month. Here are some statistics about the GBM coverage over China in the +Daily version of the product. The +Daily version features the largest database of imagery as the specifications for cloud cover and off-nadir angle are relaxed as compared to +Refresh.

    • 2015 – 12,399,810 sq km
