TerraWatchers: Crowd Sourced Satellite Image Analysis

TerraWatchers: Crowd Sourced Satellite Image Analysis

Who We Are

TerraWatchers is dedicated to providing web-based, crowdsourced satellite image monitoring and overwatch tools for critical missions related to current events. We use interactive Google Maps© interfaces to display the latest freely available, high-resolution satellite imagery in our mission footprints.

Get Involved!

The public can participate in our citizen science efforts, and get involved in our missions by registering on the form to the right. Registered users can view and annotate satellite images with markers specific to our various missions. We provide training images for our missions, so you can see what we're looking for, and how to annotate our images.
Only registered users can annotate the satellite images with observations, so please remember to Register first, using the form in the upper right corner. If you are registering, press the "Register Here" button; it will open a small form, where we collect your name, email address, a password, and a password reminder. That's all the personal information we need, and we don't share it with others. Once you've registered, you can log in with your email address and password.
