Abstract:
In order to clarify the spatial distribution of rural land management right and its transfer, to solve the land transfer inducing problems, and to provide dynamic spatial information for guiding the land policy, the spatial investigation of 1:10 000 scale rural land management right and its transfer information was developed based on high-resolution remote sensing images and mobile GIS. The key technologies were: high resolution image segmentation, boundary points interpretation, GIS drawing and mobile GIS acquisition. Ultimately the database for rural land management right and its transfer information were built. Compared to the other survey methods, such as GPS-RTK survey, single mobile GIS investigation and interpreting and drawing based on air photos, this method was more suitable for large area survey, which can keep survey accuracy, improve the work efficiency and reduce the cost of the investigation. Through Beijing case demonstration, this technical method in the future was discussed, which can provide the tech-support and workflow reference for other regions.
