Abstract

As various surveyings are done and geospatial information is actively acquired in current construction sites, demands of national control points for making or surveying of constructional floor plan are gradually increased. Therefore, this researcher drew objective and rational connective process through analysis on recent history of national control points, history of past performance and time series so as to consider demands of control points, manage performances of national control points stably, and let general people use conveniently by online. For time series analysis, through the analysis on meta data of national control points whose service was provided by national geographic information institute, this researcher firstly wrote data profile and divided into essential items and selective items by service importance. The divided items drew connective items for time series connection and service through comparative analysis with triangulation point and benchmark reported items provided currently by land information platform. The drawn connective measure should be applied to future work of national control point provision so as to contribute to national service combination of various land information, mutual connection of relative institution information, and improvement of working efficiency of spatial information.
