GHS BUILT-UP CONFIDENCE GRID (LDS)

This data grid is a complementary information layer to the multitemporal GHS built-up grid (1975, 1990, 2000, 2014). It is a quality layer, which has been produced together with the built-up data by means of Global Human Settlement Layer methodology in 2015.

This dataset is an aggregated confidence map about built-up area presence. Each pixel value represents the confidence of the model on the built-up presence.

Continuous values in the range [0 to 255]
0
127
255
0 = 100% confidence of no built-up
127 = 50% decision cut off
255 = 100% confidence of yes built-up

GHS BUILT-UP DATAMASK GRID (LDS)

This data grid is a complementary information layer to the multitemporal GHS built-up grid (1975, 1990, 2000, 2014). It is a quality layer, which has been produced together with the built-up data by means of Global Human Settlement Layer methodology in 2015.

This dataset contains a data mask as produced from the input image availabilty in each Landsat collection.
