Abstract

There is no shortage of available imagery to view the landscape of Connecticut, or any place in the world for that matter. Imagery comes in all types of spatial, spectral, radiometric and temporal resolutions, and each serves its purpose depending on the objectives of the person using it. The U.S. based Landsat series of multi-spectral satellite sensors has been collecting global imagery since 1972. A more recent satellite series, Sentinel-2, first launched in 2015 by the European Space Agency, is Landsat like and also provides global coverage. While these sensors may only provide moderate spatial resolution (10m – 60m) imagery, they are rich in spectral information, and together these satellites collect imagery over Connecticut at less than a seven-day interval. The best part, these data can be downloaded and used free. This webinar will briefly overview the Landsat and Sentinel-2 sensors, provide information about the images and how to download the data, and show examples of potential applications of this type of data in Connecticut using ArcGIS, along with some online resources for viewing the imagery.
