Abstract: With the rapid development of Global Position System, remote sensing technology and geographic information system, dynamic land information system combines these three to generate new valid data automatic collection technology. When measuring and counting land information data, valid data automatic collection technology shows completely its advantages, providing convenience for land data collection. Based on analysis of composition and technical route of this technology, land information data collection of a certain diggings is taken as an example to analyze the advantages of the technology, and the valid data automatic collection technology in dynamic land information system is thereby discussed.
