So from data obtained with the GPS, can not show visual surface of three dimensions (3D) which is very useful to estimate the volume of materials slide down. With the advance of technology Terrestrial Laser Scanner (TLS), the estimation process can be carried out. If the data is needed only per sample point for input into a mathematical model, the results of TLS requires to extraction of point cloud forming surface. While the data TLS generates 3D Digital Elevation Model (DEM) with a unit volumetric elements (voxels). So TLS observations of DEM extraction have 3D point cloud coordinate as a sample of data points monitored. For extraction required identification of the same objects at TLS image. The accuracy is obtained by TLS and GPS coordinates comparison. Temporal resolution and reliability monitor the position of the sample point of extraction TLS is still lower than the GPS positioning.[/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]Digital elevation model,Estimation process,GPS technologies,Landslide monitoring,Monitoring points,Temporal resolution,Terrestrial laser scanners,Volumetric element[/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]Extraction,GPS,TLS[/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][/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]
