![]() For instance, the management of an open pit quarry requires gaining, processing and storing a large amount of information which is constantly changing with time. Having considered how dynamic our world is, new techniques and methods should be presented in numerous fields. Secondly, the area of the whole quarry including the stockpile site was mapped by a UAV flight. Firstly, a stockpile was measured by GNSS technologies and later other terrestrial GNSS measurements for modelling the berms of the quarry were taken. For this purpose, an appropriate open pit quarry has been chosen. The following paper aims to test and evaluate the accuracy of UAV data for volumetric measurements to the conventional GNSS techniques. The accuracy of direct measurement on the LiDAR point cloud is estimated as 4mm which may open the door widely for LiDAR data to play an essential role in survey work applications. In this paper, the terrestrial LiDAR data is tested and used for several laser scanning projects having diverse goals and typology, e.g., road deformation monitoring, building façade modelling, road modelling, and stockpile modelling and volume measuring. The key to success is determined by the correct selection of suitable scanning tools for the project. However, before the employment of the laser scanning technique, it is unavoidable to assess the accuracy of the scanner being used under different circumstances. Moreover, the unmanned aerial vehicle drives the airborne scanning progress by solving the flying complexity issues. The diversity of Light Detection and Ranging (LiDAR) data applications thanks to the accuracy and the high point density in addition to the 3D data processing high speed allow laser scanning to occupy an advanced position among other spatial data acquisition technologies. ![]() Nowadays, static, mobile, terrestrial, and airborne laser scanning technologies have become familiar data sources for engineering work, especially in the area of land surveying. The results provide a significant improvement in observing and modeling of an oil plant and prove that the TLS is the most effective choice for generating a representative 3D model required for oil plant revamping. The geometric properties for tanks, vessels and pipes (radius, center coordinates, height and consequently oil volume) are also calculated and presented. All the processes to convert the observed points cloud into a 3D model are described. The modeling involves an analysis of several scans of the oil plant. etc.) using TLS observations and modeling by CADWORX program. ![]() This paper investigates creating 3D model for Ras Gharib oil plant in Egypt and determining the geometric properties of oil plant equipment (tank, vessels, pipes. TLS could be an unconventional solution as it accurately measures the coordinates identifying the position of each object within the oil plant and provide highly detailed 3D models. So it is needed to develop an accurate observations technique to overcome these difficulties. Due to the complexity of an oil plant site, there are difficulties in revamping, having all dimensions and geometric properties, getting through narrow spaces between pipes and having the description label of each object within a facility site. As facilities age, oil and gas companies often need to revamp their plants to make sure the facilities still meet their specifications. ![]() A perfect facility in the oil industry does not exist. Terrestrial laser scanner (TLS) is a new class of survey instruments to capture spatial data developed rapidly.
