Investigator Use
ArcGIS Living Atlas Wayback is a geospatial archive tool maintained by Esri that provides access to the complete history of the World Imagery basemap — high-resolution satellite and aerial imagery updated regularly since 2014. For OSINT investigators, geospatial analysts, and open-source researchers, Image Wayback enables temporal analysis of locations by comparing how a site looked at different points in time.
The tool presents a timeline of imagery captures for any location worldwide, allowing users to step through historical snapshots and compare changes. This is invaluable for tracking construction or demolition of buildings, identifying when infrastructure appeared or disappeared, observing environmental changes, and corroborating or disputing claims about when events occurred at a specific location.
For conflict zone research, Image Wayback can document the progressive destruction of structures by comparing before and after imagery. For investigative journalists, it can verify claims about when a facility was built or when activity began at a location. For counter-proliferation analysts, changes to suspected weapons-related sites can be tracked through the archived imagery stack.
The interface allows side-by-side comparison of two time periods and provides the date of each imagery acquisition, which is essential for documentation. Users can search by address or navigate the map directly to any location. The imagery is georeferenced, meaning coordinates are consistent across all time periods — allowing precise measurement of changes.
Unlike the Wayback Machine (which archives web pages), ArcGIS Image Wayback is specifically for satellite and aerial imagery. It complements other temporal imagery sources including Google Earth's historical imagery feature, NASA Worldview, and Sentinel Hub. Each source has different temporal coverage and resolution, so investigators should check multiple platforms.
Limitations include resolution variability — cloud cover, seasonal conditions, and update frequency vary by location. Rural or remote areas may have fewer captures. For high-resolution imagery in recent time periods, commercial satellite providers may be necessary.
Export specific imagery as screenshots with embedded dates and coordinates for evidentiary documentation.
