Abstract

Recently, technological developments in the field of surveys and mapping are growing very rapidly such as total station, navigation satellite (Global Navigation Satellite System), drones and laser scanners. One application of this technology is to measure a stockpile area quickly and accurately. This research will measure two stockpiles (coal warehouses) using total station (TS), GNSS and terrestrial laser scanner (TLS). This research will compare the results of volume calculations with the data generated by 3’S (TS, GNSS and TLS). Research is conducted at Coal Yard PT. Barkalin Surabaya in Benowo District, Surabaya, East City with geographically located at 112°39'11'’ E and 7°07’13‘' S. The first step is to make 3D model of Laser Scanner data by TLS Faro 3D 120 and to do regristrastion and filltering using Faro Scene. After that the data export to be 3D model from Faro Scene format to Recap 2016 (.rcp) to present and get coordinates. The next step is to compare the coordinates from TLS, TS and GNSS RTK. Finally, the accuracy of volume calculation from TS and GNSS RTK can be compared to TLS. The volume differences between TS and TLS data are -7.31 m3 (-0.45%) for the 1st location and -6.89 m3 (-0.24%) for the 2nd location. While the volume differences between GNSS RTK and TLS are -10.34 m3 (-0.63%) and -9.05 m3 (-0.31%) for the 1st location and the 2nd location respectively. Generally, the volume differences between TLS, TS and GNSS RTK are not significant. Therefore, 3’S can be used to measure a volume of stockpile.

Highlights

Surveying or land surveying is a science that aims to determine the relative positions of points above, on, or beneath the Earth’s surface
This research aims to compare the results of the calculation of the volume of coal raw materials using the 3’s (TS, terrestrial laser scanner (TLS) and GNSS RTK) in two different locations
The measurement method with total station (TS) and GNSS RTK to estimate volumes of stockpile were compared with TLS from the same site were taken and the post processing was done with a Triangulated Irregular Network (TIN) model

Summary

Introduction

Surveying or land surveying is a science that aims to determine the relative positions of points above, on, or beneath the Earth’s surface. The last few decades its importance has steadily increased with the growing demand for many applications, making a map and other spatially related types of information. Volume of earthwork is an important matter in many type of engineering project such as to determine the capacities of bins, tanks, reservoirs and buildings, to check stockpile of coal, gravel and other materials, to compute cut and fill landfill and landclearing for road and drainage engineering and construction. There are several methods for estimate the stockpile of coal volumes [1]. In the traditional method the data is obtained from a theodolite or a digital theodolite or a total station (TS)
