Unsupervised Classification
This week we performed an unsupervised classification using tools in both ArcMap and ERDAS Imagine. The image in this map is the result of an unsupervised classification in ERDAS Imagine. The final layout was created in ArcMap. Classifying this image provides a relatively accurate means of calculating surface areas. Classified images can also be used to extract vector data and create layers for features such as, buildings, roads and even telephone poles.
