TerraLook: Satellite Imagery to View a Changing World
Viewing the Earth through satellite imagery can prove useful and interesting to many outside of the remote sensing community, including science writers, field scientists, resource managers, policy makers, students, and the general public.
TerraLook permits users to create their own collections of georeferenced JPEG satellite images. TerraLook images allow for visual interpretation and comparison without the need for complicated software. While user-friendly software has been developed for TerraLook to help use the imagery, any program capable of opening JPEGs can be used. The georeferenced TerraLook collections are compatible with most GIS and Web mapping applications. All TerraLook data and software is available at no cost.
A TerraLook collection can contain one to hundreds of satellite images from a single region or many regions of the globe. These satellite images enable users to see how Earth's surface has changed from the early 1970s to the present. A TerraLook collection may consist of images selected from several satellite sensors:
You can select and order TerraLook collections using the Global Visualization Viewer, GloVis. Before using GloVis for the first time we suggest you quickly scan the How to order guide. A few moments spent with the guide will save you much time later. Note that many preselected collections have been created and archived. These preselected collections are available for download, also at no cost.
