Vertical control framework with levelling method as the based for detailed mapping in UNS Campus of Pabelan

Abstract

Detail maps are one of the outputs created by measuring soil and mapping the topography of the earth's surface on a huge scale. Preliminary steps must be completed, including the creation of fundamental mapping framework points that are evenly scattered across the area to be mapped. The goal of this study is to construct a vertical control framework and determine the accuracy of vertical control frameworks basic outline points in the form of polygons, measuring, processing data, displaying in the form of different height images and verifying their accuracy, and assessing the findings comprise the implementation technique. Vertical Control Framework measurement employs the chain levelling method and a levelling measuring tool. The results of the data analysis obtained a high difference of 8 mm in the results of the point before the correction, so the calculation of the height of the point after correction so that the height of the point equals zero in order to meet the feasibility as the basic framework of detail mapping and can be used for further measurements. The implications of the vertical control framework are utilized as a guide to generate a detail map.
