Integration of land survey data using aerial photogrammetry method on 3 dimensional bim (Building Information Modeling) Modeling

The use of UAV (Unmanned Aerial Vehicle) in land surveys and the implementation of BIM (Building Information Modeling) in the construction world has begun to be used frequently, both in the manufacture of infrastructure and building structures. The purpose of this study was to determine the effectiveness of the use of UAV in land surveys with parameters of cost, quality and time, and to find out whether the land survey can be integrated with a 3-dimensional design with applications related to BIM. This study uses secondary data in the form of aerial photo data and 3-dimensional BIM design data, which produces some data such as 3-dimensional data from the layout of a land using UAV, with a fairly good level of effectiveness compared to previous studies. In addition, the results of the integration of a 3-dimensional map of a land survey using a UAV with a 3-dimensional design of the BIM method can provide a visualization of the design form with actual conditions in the field.
