However, the use of TLS for topographic mapping should be thoroughly investigated in many aspects, including the accuracy of the observed data, the field acquisition, human resource, data processing, cost, and time acquisition. The purpose of this research is to carry out preliminary investigations. The methodology of this research consists of a reconnaissance survey, measurement planning, TLS, Total station, and Global Positioning System (GPS) data acquisition, georeferenced, filtering, 3D (Dimension) modeling and map visualization. Several aspects of the result compared with the conventional techniques by using Electronic Total Station (ETS). The results of this research show that the average error of measurements is approximately 4 mm and the detail level of the generated Digital Elevation Model (DEM) is pretty good, as it is indicated by a huge number of total point clouds (223.460 points) with the point density of about 0.25 m on optimum scanning area. TLS is suitable for a fast mapping area with a considerably large scale (1:300). In addition, based on time and human resources for mapping in the same area, the topographic mapping by TLS requires lesser time and human resources than mapping by the other methods such as ETS. The only disadvantage of using TLS is its price is still costly. As a preliminary conclusion, the TLS is more suitable to be used on high accuracy mapping, such as the reconstruction of the building, cut and fill survey, documentation of historical building.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Conventional techniques,Digital elevation model,Historical buildings,Map visualizations,Measurement planning,Reconnaissance surveys,Terrestrial laser scanners,Topographic mapping[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1088/1755-1315/389/1/012006[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
