Geospatial Forensics (Metadata)
In this lab, you will provide the geolocation and context of images via offline analytics methods. You will work with metadata to extract and interpret information, geolocate visually using satellite imagery options, and get an idea of when an image was taken. Using a limited dataset, you will examine embedded EXIF metadata to identify GPS coordinates, timestamps, and device data. You will also convert and interpret coordinate data to determine geographic regions and validate your findings using a mapping tool. You will then move into visual analysis, where metadata is no longer available. Using a set of offline satellite images, you will identify key features such as terrain, infrastructure, and structural patterns to determine the location of a target image. This simulates real-world scenarios where analysts must rely on environmental cues to determine location. In the final phase of the lab, you will perform chronolocation by analyzing shadow direction to estimate the approximate time of day an image was taken. By correlating lighting conditions with geographic orientation, you will develop a deeper understanding of temporal context in image analysis. This lab emphasizes structured reasoning, the correlation of multiple data sources, and the ability to derive location and context from limited offline artifacts.

Challenge
Extract and analyze GPS metadata from an image
Extract and analyze image metadata to identify embedded GPS coordinates, interpret capture details, and determine the geographic and temporal context of the image.
-
Challenge
Perform visual geolocation using satellite imagery
Determine the location of an image using visual analysis techniques. Identify key landmarks and environmental features, then correlate those observations with satellite imagery to identify the correct location.
-
Challenge
Determine time of day using shadow analysis
Determine the time of day an image was captured by analyzing shadow direction. Use environmental context and reference imagery to infer whether the image was taken in the morning or afternoon.
