WyomingView conducts workshop highlighting the utility of Landsat data for natural resources monitoring

WyomingView coordinator Ramesh Sivanpillai conducted a workshop at the Cable Center in Denver, CO as part of the 2012 GIS in the Rockies Conference, highlighting remote sensing concepts and the utility of Landsat data for natural resources monitoring.  This workshop introduced GIS professionals to the characteristics of remotely sensed data and how they are collected.  Participants learned how each task required data at appropriate spatial, spectral and temporal resolutions, and the consequences of working with inappropriate data.

In the second part of the workshop, participants learned about the Landsat archive and the value of earth observation data spanning over 40+ years.  Sivanpillai explained the data characteristics of the five Landsat satellites (1-5 and 7), and how these data sets can be used for monitoring changes in the surface of the earth.  Landsat images were used to demonstrate how seasonal, annual, and long-term changes can be monitored and quantified.  Participants learned to browse and download Landsat data from GloVis ( – a USGS web portal.

Participants were asked to describe how they plan to use Landsat data in their future work.  One of the participants said “After this workshop, I realize that I can use Landsat for my future work in vegetation surveys … Interestingly I also realized that Landsat can be used for business, real estate, development etc.”  Another participant, a University of Northern Colorado student said “…useful when writing geographic papers (in fact before and after map)”.  While others mentioned that they planned to use Landsat data for mapping invasive species, threats to archeological resources, and avalanche forecasting.

This WyomingView educational outreach activity was conducted on 19 September 2012 (
