Lab 4: Ground Truthing and Accuracy Assessment

Ground Truthing and Accuracy Assessment

This week I conducted a ground truthing and accuracy assessment of land use/land cover map I produced last week in lab 3. I created a point feature class to capture 30 samples in a stratified random pattern. Then I verified the accuracy of the assigned land use/land classification at each point using Google Street View. Those points that were accurate are marked with a green dot, and those points that were not accurate are marked with a red dot. The overall accuracy was calculated by dividing the total number of correct samples by the total number of samples.
