During one of my ASP.NET Core classes I made a demo about how to read GPS coordinates from photo and display location on a map. I took my favorite photo of a beer kiosk in Krakow and displayed the location of this kiosk on a map. This blog post describes my experiment on getting GPS coordinates from EXIF data in an ASP.NET Core application.

Wikipedia defines EXIF (Exchangeable image file format) as a standard that specifies the formats for images, sound, and ancillary tags used by digital cameras (including smartphones), scanners, and other systems handling image and sound files recorded by digital cameras. Most of modern devices used to take photos save meta information in EXIF format to photos. It’s great but be aware – not all people may use this information in good purposes.
