The earthwork plan application of 3D Geospatial data

In this study, an earth work design program which will improve the efficiency of earth work and enable to carry out the design using 3D Geospace-based earth work modeling in design stage was developed. Estimate of accurate earth work volume is achievable using 3D grid DEM, and based on this, a mass calculation chart was developed for movement of earth and equipment. movement and route of earth work volume and were indicated, considering construction equipment required for earth work, and to identify the work progress, the result was stored in an open API-based KML form so as to enhance the intuitive understanding of 3D visualization as well as to effectively share the analysis result.
