Abstract
Continuous modeling and monitoring of urban environmental quality (urban environmental supervision) requires updated and continuous information regarding the heat distribution model, contamination, population, security, industry and crisis management. Remote sensing is a technology that uses a series of distant measurements without any physical contact, providing useful and applicable information in accordance with various urban planning environments. The basis of remote sensing is to measure and record the physical and chemical properties of the atmosphere and the earth's surface from a remote distance, by special means called sensor, which is installed on different platforms. The sensors are divided into active and passive groups, depending on whether they themselves are the energy source or register energy reflection. LIDAR is one of the active technologies that provides special solutions for access to the information needed for urban studies and planning. LIDAR, in comparison with other remote sensors, whose source of energy is the sun and which practice imaging during the day, can collect urban data at different times of the night, and with this feature, provides access to the information required by the transportation planning, traffic, population estimates, employment, and environmental quality assessment.
