PRODUCT DESCRIPTION.

TruEarth® 15-meter imagery is the baseline for global, natural-color, Earth imagery. A complete, 3.6 Terabyte, global mid-resolution dataset, TruEarth® 15-meter imagery is ideal for web mapping, simulation, visualization and GIS applications. TruEarth® 15-meter imagery provides complete, best-available, substantially cloud-free, global coverage (except Antarctica) of the Earth at 15-meters-per-pixel resolution. We provide TruEarth® imagery in 1° x 1° drop-in GeoTIFF, ECW or JPEG2000 image tiles, each with 7,200 x 7,200 pixels.

You've seen TruEarth® on Google Earth and Google Maps... discover why TruEarth® is the preferred imagery for some of the most visible web mapping services; simulation applications; and broadcast, print and film. TruEarth® imagery is also playing an important role in next-generation Synthetic Vision aviation flight displays.

Explore the complete global TruEarth® 15-meter dataset using the TruEarth® TruViewer™ (Google Maps API enabled).

TruEarth® IMAGERY PRODUCTS.
TruEarth® 15-meter global imagery products are available in three options to provide the highest quality tuned for different applications where dataset size reduction is required.

    TruEarth® GeoTIFF Uncompressed.
Our original TruEarth® 15-meter global imagery product, perfect for the most demanding (mission critical) applications. Based on fully uncompressed lossless NASA source data with unsurpassed visual feature fidelity.

    TruEarth® ECW/JPEG2000 10:1 Compressed.  
For demanding applications where excellent visual feature fidelity and moderate dataset size reduction are required.

    TruEarth® ECW/JPEG2000 24:1 Compressed.  
Comparable in quality to competitive provider's global 15-meter imagery offerings that are based on lower-quality MrSID compressed source data. For embedded and web applications, balanced to provide high visual feature fidelity and substantial file size reduction.
