Click on a river section link above to see a sample of the nearly 4,000 photos we shot during our Chicago to Paducah survey.
We shoot Nikon D90 and D5000 bodies with Nikon GP-1 GPS sensors to instantly geo-tag each picture. Latitude, longitude, altitude, and UTC time are instantly added to each picture's EXIF header.
The Photo Map link displays each photograph in its precise location.
Photos are available for media use or commercial purchase. Please request high-resolution images at: media@onthewaterchartguides.com.
