PHOTOGRAMMETRY AND REMOTE SENSING ON URBAN AREAS

Urban areas can be considered as complex and dynamic systems, the study of which requires broad and reliable information. The required information must be improved and updated and can be collected by different sources, including photogrammetry and remote sensing. The continuous advances of these scientific disciplines in acquisition and processing of their data, but also their synergy with other modern methods and technologies (as laser scanning), make their contribution on urban areas studies (including axes of urban wide surroundings) particularly interesting. This paper refers to the above and includes a relevant example of the city of Thessaloniki, using high resolution satellite data.
