Erik Marsja: How to Extract GPS Coordinates from a Photo: The USAID Mystery
- In the digital world, photos store geolocation data like latitude and longitude if the device had GPS enabled.
- The article demonstrates how to extract GPS coordinates from a photo using Python, focusing on a USAID nutrition pack.
- Steps involved include setting up the Python environment, extracting EXIF data, and plotting the location on a map.
- The Python libraries used are Pillow for image handling, ExifRead for reading metadata, and Folium for map plotting.
- EXIF data, including GPSLatitude and GPSLongitude, is extracted to determine the photo's location.
- Coordinates are converted from degrees-minutes-seconds to decimal degrees and adjusted based on hemisphere indicators.
- The article guides in plotting the GPS coordinates on an interactive map using Folium in Python.
- Readers are prompted to interpret whether the USAID nutrition pack should be in the extracted location.
- By exploring the map, readers are encouraged to consider if the aid distribution aligns with the location shown.
- Through a few lines of Python code, the article raises questions about the photo's true location and aid distribution.
