The application The application of 3S integrated technologies based on PDA in the land survey

In order to acquire the status in quo of land use,reasonably utilize and develop land,promote the sustainable development of regional economy,it is an effective technical method to plan and manage the land resources using the integration of 3S technology by land resources department.

In this paper,3S technique integration and application in the domain of geology are introduced.

RS,GPS,GIS and 3S technique integration and its application situation in earthquake disaster are intro-duced in this paper.

Application of 3S integration technology in digital water;

The goal and key techniques in providing the technical support to the construction of "green mine" by 3S integration technology are studied.

Firstly, this paper discussed the I nternet/Web level s structure of the 3S integration for the use of dynamic trace and navigation around the technology to set up a service platform with the app li cation of 3S integration for users in conceptual aspects.

The integration of digital photogrammetly, GPS and GIS is the unique routine of the development of photogrammetly as well as the important part of the 3S integration.

A preliminary study on the application of 3S technology to precise agro-climate section in Fujian Province;

Developing 3S technology to promote agricultural modernization;

Land Use Basic Map and Data Updating Application Based on 3S Technology;
