Urban Change Extraction from High Resolution Satellite Image
نویسندگان
چکیده
Very high resolution space borne imagery is essential for a large scale and very detailed urban monitoring and the Quickbird sensor is one of those. It offers images with a spatial resolution of 0.61 m (panchromatic) and 2.44 m (four multispectral bands). Not only a mapping and cadastral surveying of urban objects can be done based on that kind of imagery. A special task is the detection of changed urban objects such as buildings and altered surface materials. This paper compares three different indices for their usability of detecting changes and finally presents a mixture of indices working best for the differentiation of man made urban objects.
