Coordinate Correction System of Leveling Line Map Based on GIS

Using geo-spatial relations of bench marks and lines, context relationship of adjacent bench marks, combining database technologie, based on registered line map using GIS method, we develop a software to solve the problem of gross error caused by the digitizing of paper bench marks. The results show that, this software can effectively recover the missing longitude and latitude information and data accuracy meet requirements, can effective control the coordinate gross error generation.
