Abstract

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. First launched in 1972, for over four decades Landsat has provided a unique resource for those who work in water resources, agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief. This webinar will provide a basic overview of the Landsat satellite and imaging sensors, where and how to acquire the freely available data, how to prepare Landsat data for use in ArcGIS, and how to calculate some derivative information.
