GeoTagging

The first GeoTagged video camera is born.

We have now GeoTagging capabilities in our 353 camera model.

This page explain current capabilities, discuss the wishes and present some examples.

Geo Tagging on Elphel cameras

EXIF

We use EXIF to store GEO data. This is a typical example of stored data:

JPEG

Here are some examples of JPEG images from Elphel 353 camera with GeoTagged EXIF: [1], [2], [3], [4]

Video

Each image in the video stream is GEO Tagged in EXIF, so even the video files such as MOV can be parsed to extract GEO Tagging information from each particular frame. Here are some HD and 5MPix video examples: [5], [6], [7]

Applications

There are multiple possible application of GEO Tagging. Here are some of them:

Flickr / Panoramio / ...

You can upload JPEGs from Elphel camera to Flickr, Panoramio or any similar service. EXIF data will be recognized and the images will be automatically placed on the world map.

Here is an example.

Google Map

- a google map with a sequence of images. Each thumbnail is linked to the high definition image.

Google Earth

Here is a KML file for Google Earth with links to photos stored on our server.

Needed hardware & software

We used Elphel 353 model with 10369 board mounted inside.

Compass

We used a Ocean 5000 compass that is mounted inside the camera and connected to the USB on 10369 board.

GPS

Garmin GPS18 was used as external USB GPS
