Solution
Urban change detection is effectively undertaken in GIS core using overlay operations.
Explanation:
Overlay operations in GIS are used to superimpose multiple layers of spatial data from different time periods to identify relationships and patterns of change between them. For example, overlaying urban land-use maps from 1974 and 2001 clearly depicts urban sprawl and other changes over that period. This method is fundamental to land-use/land-cover change detection and environmental monitoring.
