Worldview is a visualization tool that allows the user to browse satellite imagery products from LANCE (Land Atmosphere Near real-time Capability for EOS) centered on your school or observation site by referencing your registered latitude and longitude. Worldview provides near-real time (NRT) data and imagery, which means you can compare data within three hours of your observation.
