Participants saw the value of Landsat's infrared bands for highlighting crop growth differences and how reflectance values in those bands can be related to growth patterns (or vigor). They collected reflectance values of features such as crops, rangelands, water and built surfaces (asphalt roads) to gain insights about how each feature interacted with electromagnetic radiation.
Finally, using a measurement tool in EVF, they learned to calculate areas of poor, medium and low growth within a field. Other sources of satellite and aerial images (SPOT, IRS, IKONOS and Quickbird) for agricultural applications were discussed.
Participants provided the following (anonymous) feedback about this workshop:
- Excellent. Has peaked [sic] my interest in research applications of this technology
- Amazing freeware. Almost as powerful as the old ERDAS software I have used
- Great workshop. I appreciate the background information and all the examples
- Good workshop, very interesting!
This WyomingView education and outreach activity was conducted by Ramesh Sivanpillai on 24 Feb 2006 as part of the annual Wyoming Agriculture Experiment Station's Research & Extension Center Planning Conference.
