Urban Remote Sensing and Urban Geo-information System

In 20th century, the Airborne Photogrammetry and the Airborne Remote Sensing played an important role in the process of the urbanization, the plan and the management of cities and towns in China. In 21th century, the Satellite Remote Sensing will exert a more effect in extensive area. In this paper, the advancement of exploiting of the urban remote sensing and urban geographic information system in China in the last twenty years is reviewed in detail. As a result, it is shown that the satellite image data and three-dimensional airborne remote sensing are more close to meet the requirements of the rapid development of cities. The high resolution and multi-spectrum satellite image data offer an unprecedented advantage to the construction and the update of the urban geographic information system.
