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.

ACQUISITION OF FOREST RESOURCES DATA 1.2 The Application of GPS Technology for Acquisition of
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

Forest Resources Data
(1) Sentinel information on the topic
(2) provide or renew spatial positioning
(3) geometric registration auxiliary classification
(4) provide or update regional information
(5) geometric correction, training selection and classification of
verification
(6) provide information inqury of remote
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
