“…The user needs to switch between several viewpoints to navigate through the virtual environment; this is unnatural and cumbersome, reducing realism and the immersion of the virtual lab. Other simpler attempts include software for training students on how to read a leveling rod [35] and control point selection for terrain modeling [36]. In surveying engineering, students must operate complicated instruments with several components.…”

Experiential learning through outdoor labs is an integral component of surveying education. Cancelled labs as a result of weather, the inability to visit a wide variety of terrain location, recent distance education requirements create significant instructional challenges. In this paper, we present a software solution called surveying reality (SurReal); this software allows for students to conduct immersive and interactive virtual reality labs. This paper discusses the development of a virtual differential leveling lab. The developed software faithfully replicates major steps followed in the field and any skills learned in virtual reality are transferable in the physical world. Furthermore, this paper presents a novel technique for leveling multi-legged objects like a tripod on variable terrain. This method relies solely on geometric modeling and does not require physical simulation of the tripod. This increases efficiency and ensures that the user experiences at least 60 frames per second, thus reducing lagging and creating a pleasant experience for the user. We conduct two leveling examples, a three-benchmark loop and a point-to-point leveling line. Both surveys had a misclosure of 1 mm due to observational random errors, which demonstrated that leveling can be conducted with mm-level precision, much like in the physical world.

“…This research study demonstrates a very useful connection of the gaming application scenarios with learning outcomes and their assessments in the frame of cyberlearning; however, implementation of the variety of the specific surveying technologies and instruments may serve as a complication factor for the creation of generic application scenarios. The most interesting work was performed in [20] where online training was focused on digital terrain modeling practice. The challenge of current research is to develop a cyberlearning approach for terrain data collection specifically for topographic surveying.…”

In spite of the tremendous success in artificial intelligence technology and a high level of automation in geospatial data obtaining processes, there is still a need for topographical field data collection by professional surveyors. Understanding terrain topology and topography is a cognitive skill set that has to be demonstrated by geospatial Subject Matter Experts (SME) for the productive work in the topographic surveying field. For training of the mentioned above skillset, one has to be exposed to the theory and must also practice with surveying instruments in field conditions. The challenge of any surveying/geospatial engineering workforce training is to expose students to field conditions which might be limited due to equipment expenses and meteorological conditions that prevent good data collection. To meet this challenge, the Integrated Geospatial Technology research group is working on a geospatial virtual reality (VR) project which encompasses the following components: (a) immersive visualization of terrain; (b) virtual total station instrument; (c) virtual surveyor with reflector installed on the virtual rod. The application scenario of the technology we are working with has the following stages: (1) student is installing total station on the optimal location; (2) students move virtual surveyor on the sampling points they consider to be important (3) contours are generated and displayed in 3D being superimposed on 3D terrain; (4) accuracy of terrain modeling is observable and measurable by comparing the sampling model with initial one.

Abstract-Due to the complexity of network, the original teaching method cannot meet the needs of development of network. Network simulation is an effective means of researching in network protocols and a new kind of network design and optimization technique, it can provide reliable network planning design of quantitative basis, also can test plan, or compare different design schemes. This paper introduces the principle and characteristic of ns3, proposes using open source software ns3 as an assistant means to improve the teaching quality, and also discusses the application of ns3 in network education as well. An example is provided at the end of this paper.
