Abstract
Remote sensing application and research in Guangdong Province has achieved great development over the past ten years. Up to now eight remote sensing application and research stations or centers or experimental sites have been established in different fields Besides south China forestry Remote sensing Experimental Station has been built in Nankun Mountain and Pearl River estuary Comprehensive Experimental Site, one of the two sites for China’s resources satellites will also be put to use this year a part from the aerial system for remote sensing information acquisition equipments for spectral testing ground information processing and remote sensing mapping can basically meet the needs for multi discipline application of re,ote sensing .Remote sensing technology has been applied to more then 30 units in areas environment protection urban planning and remote sensing mapping further more. Some large scale comprehensive applications have also been carried out such as the comprehensive aerials remote sensing survey of Guangdong city. In some areas remote sensing has become a mature and indispensable method while space remote data are extensively used infrared color natural color and multi spectral aerial photography has also been frequently conducted with in Guangdong Province Airborne thermal infrared scanning applications More ever digital image processing as well as quantitative and dynamic remote sensing are making progress and a number of special remote sensing databases have been gradually set up. All this indicates the enhancements of remote sensing application level remote sensing work in Guangdong Province has achieved remarkable benefits making Gunagang an important base for remote sensing application and research inChina.
Founded in 1979 Guangdong province remote sensing society is now 11 years old with a membership of 362 in the past ten years remote sensing application and research in Guangdong has made great head way with continuous expansion of application fields and rapid improvement of technology there have been a great number of application and research results manifesting good social and economic benefits of remote sensing Extensive application and research with large scale and depth specially features the remote sensing development in Guangdong province results and benefits of remote sensing application and research in various fields are briefly presented in the paper below.
Province Wide Land utilization Survey
Detailed investigation of current land utilization is one of the basic projects under national conditions investigation program under the unified organization technical guidance and quality supervision of Guangdong provincial land management department the latest aerial photos were used and the survey personnel were given short term training then the survey was carried out region rapidly and smoothly over the whole province during the survey orthographic images were used instead of the outdated topographic maps with indoor interpretation as the main method plus necessary field reconnaissance finally the survey was completed through precision transfer mapping and calculation in this way not only the survey cost was greatly but also the survey quality and speed was raised the survey findings jhave provided a basis for national land management and planning.
