TerraLook

(formerly known as the Protected Area Archive)

TerraLook provides access to satellite images for users that may lack prior experience with remote sensing or Geographic Information System (GIS) technology. It does this by combining collections of images on user-defined themes with a set of simple visualization and analysis tools, allowing the user to explore the data and employ it for useful purposes. The images include recent high-resolution ASTER images, plus Landsat images from several historical periods going back to the early '70s. Such historical data supports change analysis.

Simplicity is an overarching principle. TerraLook was designed to overcome the obstacles that limit access to data by user communities lacking sophisticated tools and skills.

TerraLook is of use to a wide variety of disciplines including conservation, development planning, education, urban studies, disaster planning and response, and others. It may be of particular use in developing countries that may have less capacity to purchase or work with remote sensing data.

TerraLook consists of two parts: Image Collections based on themes, and the Software to work with them.

Image Collections. Users can create their own custom collections of images by visiting the USGS TerraLook website,  Using the USGS Glovis tool, the images are selected, the collection built, and the user notified that it is available for download.

Also, many standard collections have been archived and are available for download from the Downloads page of this ASTER TerraLook website. Typically, these consist of country collections, containing full-country coverage with the historical Landsat images from 1975, 1990, and 2000, plus ASTER coverage of the Protected Areas of the country.

Image Collections: Users can create their own custom collections of images by visiting the USGS TerraLook website

Also, a variety of existing collections are available for ftp download.


Software: This software is a simple and intuitive desktop application that is convenient for finding the images of interest in a collection, and then doing useful things with them.
