We're starting off the course on Photo Interpretation and Remote Sensing by examining aerial photographs, and this week we specifically looked at different methods of identifying the features in an image.
The image below explores the range of tones and textures that can exist in a single photograph. Tone and texture can help in identifying a feature.
Features can also be identified by their size and shape, by the shape of the shadows they cast, because they form a pattern, or based on their association with other identifiable features. The image below shows some examples.
