I wrote an open vector building before open building ：

(1229 Bar message ) Global building extraction dataset （ As a free download ）： Microsoft /GlobalMLBuildingFootprints_ This star bright blog -CSDN Blog _ Building data set

This large-scale public data set includes high-resolution 50 The outline of the building from the centimeter satellite image . It contains 5.16 Inspection results of billion buildings , Area is 1,940 10,000 square kilometers （ Of the African continent 64%）.

For every building in this dataset , We all include polygons that describe their footprints on the ground 、 A score indicating our confidence in the certainty of a building , And corresponding to the building center Plus Code . There is no information about the type of building 、 Street address or any details other than geometry .

Building footprints are useful for a number of important applications ： From population estimation 、 Urban planning and humanitarian response to environmental and climate science . The project is located in Ghana , The current focus is on the African continent .

The inference work is in 2021 year 4 During the month .

See the official website of the open building data set for more details .
