Locate an image or change
Compare map landmarks, satellite acquisitions and observation layers with their dates.
Views with different resolutions and processing cannot be treated as identical photographs.
Compare sourcesCompare imagery of an area
Fix area and dates, open USGS and Copernicus scenes, then use NASA Worldview to place the change in context.
Sensors, resolution, cloud cover and processing differ; similar colors do not prove identical ground conditions.
