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.

Here are some key features of "TerraLook":

· 15m pixel ASTER data (2000 - present)
· 30 and 80m pixel Landsat data (from c. 1975, 1990, and 2000)
· 4m pixel IKONOS data (when available…which is rarely)
· Image find, roam, and zoom
· Image annotation with text, arrows, etc
· Creation, display and management of vector overlays
· Distance and area measurement
· Image comparison via FLICKER
· Image mosaicking
