Building Recognition Analysis (BR)

Tanzania building recognition analysis

BR stands for Building Recognition analysis used to provide an up to date, digital overview of the location and footprint of buildings. A Spottitt automated self-service BR is derived from commercial sub meter resolution imagery via our neural network algorithms trained on a diverse global dataset. A Spottitt BR can be used as a stand alone analysis, for example clients surveying off-grid villages; or as a critical input to generate a Spottitt Green Field Analysis.

A Spottitt BR has 2m resolution, is derived from commercial sub meter resolution satellite imagery, and takes between 12-24 hours to generate for any location globally. See full product specifications below.

This is a BR analysis for a remote site in northern Tanzania. View the full analysis and 50cm resolution imagery used to generate it in Spottitt here.
