Basics of Remote Sensing & Application for CCA's

Remotely sensed data may enhance your abilities to focus on problem areas within a field. It can also assist you in predetermining by the patterns shown on remote sensed images as to whether one is dealing with a nutrient, pest, soil condition or management problems. It doesn’t alleviate one from not going to the field. In fact, ground reference data is your most valuable friend when using remotely sensing data. This presentation will cover types of available remote sensing data, types of image displays, ground reference (sometimes called ground truth) that assists one in analyzing or interpreting the data/images and ways that you can use remote sensing in your CCA work.
