The objectives of lab 7 were to look at the histograms of an image and use tools to look at data. By looking at the histogram, an objective was to interpret the data. Within ERDAS, also use the Inquire Cursor tool to look at pixel data and find tools from the Help Tab. After going through all the exercises, applied skills to identify features.
By looking at the metadata histograms, I was able to see if the features I was looking for were dark or light. The size of the spike also told me if the feature was large or small. Once I had an idea of the brightness and size, I used the inquire cursor to see pixel count. I was then able to see the pixel count for each layer and see if it matched the clues. I then adjusted the color to spectrum to help highlight the features I needed to find.
