Abstract <br>In recent years, along with in-depth study of forestry-related digital positioning technology in these areas continue to expand, while the precision and efficiency of the relevant technical requirements are also rising, the traditional right to forest land and a single measurement technology can not meet now woodland is indeed the right job requirements. Therefore, in order to meet the development process is indeed the right of woodland, will continue to optimize and innovation "3S" technology application into the forest. This paper focuses on "3S" technology applications and related technology in the right to do woodland. <br>This article describes the new direction of the current "3S" technology in the forestry sector, focusing on a global satellite navigation and positioning system "3S" technology, UAV photogrammetry, GPS static observation, CAD secondary development and application CASS10 software. The first secondary development of CAD software applications and CASS10 to the application of forestry-related work. To investigate the feasibility of using high process Development of CAD data processing and controlling forest right to do the measurement points selected in the layout. <br>In this paper, combined with the current development status and trends of "3S" technology, exploration of the "3S" techniques cited were using to do the right woodland, new technology development is indeed the right of woodland, at the same time meet the "3S" the rapid development of application technology practice needs. <br>Keywords: CORS, UAV, photogrammetry, measurement control, the right forest land, the second CAD development

Summary<br>In recent years, with the deepening of forestry digital-related research, positioning technology in its application areas continue to expand, at the same time the accuracy and work efficiency requirements of related technologies are also constantly improving, the traditional forest land right and single measurement technology can not meet the current forest land right of the work demand. Therefore, in order to meet the development process of forest land tenure, the continuous optimization and innovation of "3S" technology will be applied to forestry. This paper focuses on the application of "3S" technology in forest land tenure and related technical means.<br>This paper introduces the new development direction of "3S" technology in forestry, and focuses on the application of "3S" technology in global satellite navigation and positioning system, drone photogrammetry, GPS static observation, CAD secondary development and CASS10 software. For the first time, CAD secondary development and CASS10 software were applied to the application of forestry related work. The feasibility of using CAD secondary development to process efficient processing in forest land confirmation data processing and control of measurement selection.<br>This paper studies and combines the current development of "3S" technology, exploratory reference of "3S" technology to the right to forest land for use, for the development of forest land right to provide a new technical means, while catering to the "3S" technology rapid development of practical application needs.<br>Keywords: CORS, drones, photogrammetry, control measurement, woodland, CAD secondary development

abstract<br>In recent years, with the deepening of forestry digital related research, positioning technology is expanding in its application field, and the requirements for the accuracy and efficiency of related technologies are also increasing. The traditional forest land right confirmation and single measurement technology can not meet the current work needs of forest land right confirmation. Therefore, in order to meet the development process of forest land right confirmation, the "3S" technology will be continuously optimized and innovated and applied to forestry. This paper focuses on the application of "3S" technology in the confirmation of forest land rights and related technical means.<br>This paper introduces the new development direction of "3S" technology in forestry, focusing on the global satellite navigation and positioning system, UAV photogrammetry, GPS static observation, CAD secondary development and cass10 software application. For the first time, CAD secondary development and cass10 software are applied to forestry related work. This paper discusses the feasibility of using CAD secondary development to deal with the data processing of forest land weight determination and the layout of control survey points.<br>In this paper, combined with the current situation and trend of "3S" technology development, the "3S" technology is used in the forest land confirmation, which provides a new technical means for the development of forest land confirmation, and meets the needs of the rapid development of "3S" technology in practice.<br>Key words: CORS, UAV, photogrammetry, control survey, forest land right confirmation, CAD secondary development<br>
