The Survey of Accuracy Analysis of Remote Sensing and Gis
نویسندگان
چکیده
With the fast development of cities in China, more and more geographic information systems (GIS) that have been combined with remote sensing information are applied to help decision-maker or company to manage and make macroscopic decisions. But the accuracy of integrated GIS was ignored by both user and producer. It followed that the uncertainty of GIS may result in wrong decision. For these reasons, it is necessary to evaluate and analyze the accuracy of GIS and remote sensing information. In this paper, the general situation of integrated GIS in Shanghai was introduced, uncertainties of GIS and remote sensing were demonstrated, and where uncertainties exist in and what cause more uncertainties in the course of producing GIS were analyzed.
