DigitalGlobe created a consistent, high-resolution imagery base map for all of Africa at 50-cm ground resolution.

DigitalGlobe released a high-resolution satellite imagery base layer for Africa at 50-cm ground resolution. The map focuses on completeness and consistent quality to allow governments and global development agencies to use the data to derive road layers and other data.

The effort involved a country-by-country focus to be sure all of Africa was built with this unique and high-resolution data source. The base map comes at a time when Africa’s rapidly growing economy needs it most.

The data product, called Basemap +Vivid, delivers Web-enabled data. Six years of 50-cm imagery from the company’s archive went into creating the product.

“This is an important accomplishment in response to requests from our customers to create a verifiable, authoritative base map covering the entire continent,” said Hyune Hand, DigitalGlobe's senior vice president for Product Marketing and Management. “Demand continues to grow, fueled by both regional projects and programs that require consistent, quality coverage of an entire country.”

DigitalGlobe put the imagery through automated image processing tools to align the images, balance the color, adjust for seasonal changes, remove haze and cloud cover, and provide a consistent data product.
