Exif and Geo-data

More and more modern digital cameras and smarphones have a built-in GPS module.
They record the latitude, longitude and elevation at the time a photo is taken (and other data in EXIF (Exchangeable image file format): https://en.wikipedia.org/wiki/Exif).

There are Meta information in a wide variety of files. There are different metadata formats including
  • EXIF, GPS, IPTC, XMP, JFIF, GeoTIFF, ICC Profile, Photoshop IRB, FlashPix, AFCP, ID3, 
  • as well as the maker notes of many digital cameras by Canon, Casio, DJI, FLIR, FujiFilm, GE, HP, JVC/Victor, Kodak, Leaf, Minolta/Konica-Minolta, Motorola, Nikon, Nintendo, Olympus/Epson, Panasonic/Leica, Pentax/Asahi, Phase One, Reconyx, Ricoh, Samsung, Sanyo, Sigma/Foveon, Sony...
Different methods of geotaging:

In regards to Point of interest (POI), many different file formats, including proprietary formats, are used to store point of interest data, even where the same underlying WGS84 system is used.
Some useful links which could be a basis of a metadata POI

PGE uses the Google Maps to show the coordinates of a photo. This means the application requires an active Internet connection: you can't use PGE offline.

There are several possibilities to locate a photo in Photo GPS Extract:
  • Launch the program and open a photo through the menu File - Load Photo.
  • Drag a JPG from your desktop or Windows Explorer, then drop it over PGE's main screen.
  • Right-Click any JPG photo in Windows Explorer. Then click the "Send To" menu and select "Photo GPS Extract". PGE will now be opened and display the location of the photo.
  • Right-click a JPG photo in Windows Explorer and select "Show GPS Location On A Map". (Please note you need to activate the option 'shell integration' before you can use this feature).
The Batch GPS Extractor is a tool to extract the coordinates from all pictures in a certain folder on your computer. This data can then be exported to a CSV file (Comma Separated Values) or a Google Earth .KML file. The Google Earth KML file generator offers a lot of options to customize your file.

Embedded map generator: Photo GPS Extract can generate the HTML code for your own embedded Google Map. This map can then be integrated in your website or BLOG (see the dialog was used to create the Google Maps).
Rem: "I deliberately decided NOT to build a geotagging feature. The design philosophy of Photo GPS Extract has always been the same: the software does NOT alter your photos in any ways."
