Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer

Accuracy assessment is an important final step of the classification process. The goal is to quantitatively determine how effectively pixels were groups into the correct land cover classes. The procedure is relatively simple. Pixels are randomly selected throughout the image using a specified random distribution method. Then the analyst uses the original image along with ancilliary information such as aerial photographs or direct field observation to determine the true land cover represented by each
