TerraLook

TerraLook is a collaborative project that provides access to satellite images for users that have no prior experience with  Geographic Information System (GIS) technology or remote sensing.

Formerly known as the Protected Area Archive, TerraLook combines collections of georeferenced JPEG images with a set of simple visualization and analysis tools.

TerraLook allows users to explore the data and employ it for useful purposes in a 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. The program allows image comparison using 'flicker' tool and also distance and area measurements.
