TerraMetrics TruViewer – Our standard TruEarth® benchmark viewer.
TerraMetrics provides two online demonstrations of the full expanse of the global TruEarth® 15-meter imagery database that may help in your analysis and comparison of products. The online demos show different characteristics of the global TruEarth® imagery. If you have questions regarding TruEarth® imagery in Google Earth, please visit our Google Earth FAQs link.
TruViewer Demonstrator #1
This is a Google Maps demo that shows subsampled, 480-meter global-coverage imagery in its native geographic projection. It offers several versions of imagery, defaulting to the “TruEarth15 480m Bath” format which shows the TruEarth® 15-meter imagery (subsampled to the lower 480-meter resolution) matted on top of synthetic bathymetric ocean imagery. At the upper-left, click on the “TruEarth15 480m Native” button to view the raw TruEarth® 15-meter imagery, as it is delivered, only at the lower 480-meter resolution.
Note: The “TruEarth15 480m Native” imagery option is our standard benchmark for customers to examine and qualify the cloud cover, coverage area and general visual characteristics of the global TruEarth® 15-meter dataset.

TruViewer Demonstrator #2
This demonstration is based on leaflet.js and shows subsampled, 480-meter global-coverage imagery projected into the common web-based Spherical Mercator projection. This demo includes full 15-meter resolution within the continental U.S. area, outlined by the dashed lines that you’ll see when you zoom way out. The 480-meter resolution data is shown on top of the synthetic bathymetric ocean imagery, as in the first demo.
