GeoExif Mapper

Put available photo coordinates and recorded times side by side before interpreting them. The map and source table make that comparison visible, but the metadata does not independently establish who took the images or travelled between the points.

Demonstrated on constructed training data

What location and time metadata does the image itself contain?

Start with

Constructed JPEGs with EXIF GPS coordinates at known landmarks.

What you can take away

Photo metadata, map and timeline views with point-to-point distance calculations.

Compare four assigned GPS positions extracted from training photographs. The map links the points in recorded time order; it does not reconstruct a person's journey. The locations are real and the activity is invented. Map data: OpenStreetMap contributors.

Open the screenshot and choose “View actual size” to read the records at their original resolution.

A practical starting point

How the workflow fits together.

Extract the available metadata from the selected images.
Compare recorded coordinates and timestamps in the map and chronology.
Keep metadata-derived locations separate from claims about a person's movements.

Useful next steps

Bring a sample question.

Ask us to demonstrate this workflow with suitable public or constructed material. Do not send confidential evidence in an initial enquiry.

About the screenshots and illustrations

Application screens are selected from the September 2026 Acorn screenshot pack. Captions distinguish native setup views, constructed training records and public-corpus results. They are not private client cases, and a displayed control does not establish that every operation was completed.

Relevant public sources include DeepBlueCLI training event logs and Plaso test data. Check the relevant source terms before redistributing an underlying dataset.

Workspace scenes and sector mascot variants are generated illustrations. They do not show actual police, judicial, military or university deployments or endorsements. The original Squirrel Forensics identity is retained.
