Wonderful project and write-up from Mark Williams up on ozzmaker.com.
In this post we will show you how to geotag and capture the “attitude” of photos taken with the Raspberry Pi camera and record these values within the photo itself using EXIF metadata
We used a modified (hacked?) cap to take the images in this post. The cap took photos, geo-tagged and recorded attitude as we walked around Sydney Harbour.
