Complete Cedar Valley trail project

Posted Sept. 18, 2019, 12:13 p.m.

The GeoTREE Center completed a project funded by the Cedar Trails in which they captured 360° imagery from approximately 20 miles of the local hard-surface recreational trail system in the Cedar Falls-Waterloo area. All 360° imagery were published to Google Street View. Over 1700 photos were published to Google Street View and as of September 2019 Google reported >150,000 views of those images. Below is a map of locations of photos displayed by number of views on Google around Big Woods Lake in Cedar Falls.  A story about the project appeared in the Waterloo Courier. The GeoTREE Center built two web virtual tour or story map apps to increase visibility of the local trail system. See the story map and virtual tour
