CADASTRAL SURVEY TOTAL MANAGEMENT SYSTEM

摘要

A system for managing a cadastral survey network integrally is provided to integrally store/manage data related to cadastral survey data such as reference cadastral point data, parcel-based cadastral survey network data, and survey angle data, which are used as a reference for cadastral survey when a cadastral map is made, offer an effective data model representing connection among the data, and restore a reference cadastral point. A data I/O(Input/Output) device inputs/outputs reference cadastral point data, parcel-based cadastral survey network data, and survey angle data, and corresponding history data. A database includes the reference cadastral point data, the parcel-based cadastral survey network data, the survey angle data, and a data connection table. An integrated cadastral survey network adjustor, an excessive error survey value detector, an excessive error reference point result detector, a reference cadastral point connection information searcher, and reference cadastral point-cadastral map connection information searcher use the data stored in the database. The reference cadastral point data includes planar coordinates of a cadastral triangular point, a sub cadastral triangular point, and a root cadastral map point.
