RESEARCH ON DATE COLLECTING AND RAPID MAP UPDATING OF FOREST 
RESOURCES BASED ON 3S TECHNOLOGY 
In this paper, the integration of “3S” technology is used to acquire forest resources information as well as to update related maps. It 
methodology systems of forest resources management. It forms dynamic monitoring technological system of forest resources with 
aerospace, aviation remote sensing and ground survey. Thus we can analyze and appraise forest resources, which provide the 
technical support for improving the environment and promoting the sustainable development of society and economy. Forests are the 
main body of ecosystem and the basis of forestry estate, which play an important role in improving environment, promoting the 
sustainable development of society. Forest resources are an important component of state-owned resource and the national wealth, 
which is the basis of the life on earth. It is the urgent mission to measure current situation of forest resources, to monitor dynamic 
systematic change, to analyze quantity, quality, distribution, healthy status and multifunction and to make a preliminary estimation of 
its trend.

and use of remote sense information, and GPS technology has present, GPS precise localization technology has found 
fine accuracy basis for the remote sense and GIS, also being an of science and technology. Every link of the investigation, the

The technique of remote sensing has provided space-time array GPS not only has the global character, all-weather, the 
information source of different precision, and GIS technology continual precise three dimensional navigation and localization 
provided accurate spatial positioning, which has controlled a widespread application in economic development and domains

plan, the management, the monitor, the appraisal, the forecast, 
the decision-making of forest resources need the current, 
objective and accurate information. The GPS provides the 
ground datum for the remote sensing to gain the ground data, 
simultaneously the remote sensing technology has gained the 
surface information macroscopically, comprehensively, 
dynamically, and fast, which has become one of most effective 
information acquisition methods in the modem forest resources 
research, and has provided the powerful technical support for 
the extraction of forest ecosystem space information, the 
dynamic continuous fast monitoring of resources and the quota

RS has provided the unique technical method for the resources 
investigation and the environmental monitoring by its 
macroscopic, comprehensive, and dynamic characteristics. The 
remote sensing system is a collection of many kinds of sensors, 
the multistage resolution, and the multi-spectral coverage 
which takes the quantization as the goal, and takes the Earth 
system as the study object with GIS, the GPS integration
