Module 2 - Land Use Land Cover Classification (LULC), Ground Truthing & Accuracy Assessment.
This week’s assignment focused on learning how to classify land use and land cover (LULC) from high-resolution satellite imagery and then evaluate how accurate those classifications were. We worked with an aerial image of Pascagoula, Mississippi, and created our own data by digitizing different land use types. First, I created a new polygon feature class and digitized different land cover areas by identifying patterns of tone, texture, shape, and association. I assigned each polygon a Level II LULC code and a short description. My final categories included residential (11) , commercial and services (12) , deciduous forest (41) , forested wetlands (61) , non-forested wetlands (62) , lakes (52) , streams and canals (51) , and bays and estuaries (54) . Learning to recognize these features based on visual cues made me more aware of how land use reflects both natural environments and human activity. Next, I conducted a ground truth accuracy assessment . I created 30 sample points arou...
