Older Versions and Changelog

This software greatly reduces the time and effort required to geotag and watermark surveying photos, by processing them in real-time. Images are tagged with GPS data as well as other optional meta-data, and can be watermarked so this information is visible on the image. This means that photos can be ready for hand-off to the customer the moment that you’re finished shooting. No messy and time-consuming post-processing is required. It's a favorite of the Massachusetts Wing of the Civil Air Patrol (USAF Auxiliary) for time-critical disaster damage assesment, and other aerial photography missions.


Sample Output (automatically watermarked)


  1. Microsoft Windows-based computer (XP, Vista or 7).
  2. Garmin GPS unit.
  3. Camera which allows for tethered shooting to your computer (tethered shooting means that the photo gets transferred to a location on your computer as soon as you take it with your camera).

Tethering Methods

For this software to work properly, your camera has to transfer images to your computer as soon as they are taken. The methods to do this vary greatly by camera type and manufacturer. All methods use specialized third-party software, and most require you to connect your camera to your computer via a USB cable.

  • Adobe Photoshop Lightroom will tether with many popular professional and prosumer digital SLR cameras.
  • Canon DLSR cameras come bundled with their free EOS Utility software, which supports tethered shooting.
  • Capture NX supports tethered shooting with Nikon DSLR cameras.
  • Camera Control software is free and supports a number of Nikon DLSR cameras.
  • Additional tethered shooting software can be found by doing some light Googling.

The above methods work only for DLSR cameras. If you have a consumer-oriented compact (point & shoot) camera, you’ll have to use a different tethering method. Eye-Fi is a company which sells wireless-enabled SD memory cards. Their Eye-Fi Pro X2 memory card allows for photo tethering wirelessly (over Wi-Fi / 802.11n) through an ad-hoc network which can be created with your computer. If you choose to use this method, be sure to purchase the Pro version of the card, as it’s the only one that supports ad-hoc networked tethering.
