Abstract:Accompanying with cadastral management technology development, in the introduction of a unified national geodetic coordinate measurement techniques, in order to meet the demand of linear distribution of railway land and daily management, railway land cadastre management still retains an independent coordinate system. Due to constant updated equipment and technical equipments, railway line equipment occurred more dial, shift and change lines or diverted. As a confirmation to the railway line position baseline, railway line changes had a direct impact to find the railway property line quickly and accurately. Pointing to the reference coordinate changes and adjustment of railway land have been studied in further, and feasible suggestions have been put forward as well.
