Service

Urban Expansion Monitoring

Provided by Serco

The service maps built-up extent at successive epochs and turns the difference into the numbers a planner or a development bank actually asks for: hectares added, rate of expansion, direction of growth, and the share of new settlement that landed on floodplain, steep slope or protected land.

It combines radar and optical: new construction changes the structure of a surface before it changes its colour, and radar sees that structural change through cloud and at night.
