[Core] Image GPS Extraction

[mikegehard]

As a system processor, I need to extract accurate GPS coordinates from uploaded images to properly locate downed trees.

Given/When/Then:
Given an image has been uploaded to the R2 storage
When the image processor retrieves the image
Then the system should:

• Extract EXIF metadata from the image
• Parse GPS coordinates from the metadata
• Validate coordinates are within expected range
• Store coordinates with accuracy information

Technical Notes:

• Use Sharp for image processing in Workers environment
• Implement EXIF metadata extraction
• Add coordinate validation logic
• Store results in KV storage

• Test with image from computer
• Test with image taken on phone and then attached

When I attach the same photo used from computer on my phone, no GPS data is present. :-(
Need to figure out why

If you take the picture using the GMail app, it does not include the GPS data.
If you take the picture, with location services on for camera, and attach in GMail app it works.
If you take the picture, with location services on for camera, and send from picture using GMail it works.
