Application of Web 3D GIS to Display Urban Model and Solar Energy Analysis using The Unmanned Aerial Vehicle (UAV) Data (Case Study: National Cheng Kung University Buildings)

Abstract

Nowadays, the era encompasses everything smart, whether they are smartphones, smart people, or smart cities. The term ‘Smart Cities’ refers to an advanced urban town that has well-connected infrastructure and communication through data centers and automated networks, unless for the energy system. Solar energy is one kind of renewable energy. It is a clean, sustainable, and free energy source both for the public and governments. With the rapidly growing technology, the yield of solar energy increases, while its cost reduces. Thus, it gains importance and becomes widespread. Presently, the increasing importance of solar power makes a hot topic. We are currently facing a global warming issue where one of the leading causes is the use of fossil energies. Non-fossil energy, or better known as renewable energy, is an option to reduce the use of fossil energy as an effort to minimize the impacts of global warming. In this study, we collected the data from The Unmanned Aerial Vehicle (UAV) that is combined with GPS and IMU technology to get the 3D campus model in National Cheng Kung University (NCKU), Taiwan. The output of the data is true ortho-image, digital surface model (DSM), and building footprint. The building footprint was processed using the Autodesk Insight 360 and Autodesk Revit to get better 3d campus model. All three data were processed using ArcGIS Pro using Calculate Solar Radiation plugin. The result of this step is reaching the solar energy potential of NCKU. The final step is to show it into the Web 3D GIS to display the result. From the Web 3D GIS, everyone can access the information of NCKU solar energy potential using computer and also smartphones.

Advancements and Applications of Drone-Integrated Geographic Information System Technology—A Review

“…This information can be used to optimize resource allocation, improve public safety, and enhance the overall quality of life for residents. For example, drones equipped with thermal imaging cameras can be used to detect heat loss from buildings, which can help city planners to identify areas that require insulation or other energy-saving measures [72]. Drones can also be used to monitor traffic flow, identify congested areas, and optimize traffic signal timings to reduce traffic congestion and improve public transportation [73].…”

Electric hybrid airship with unlimited flight time

“…Lighter-than-air aircrafts have been always caught attention [1][2][3]. Nowadays new materials, new power sources, more advanced solar panels, modern control and navigation systems are being created [4][5][6][7][8][9]. This contributes to the creation of new type of aircraft, in particular unmanned aerial vehicles with unlimited flight time [10][11][12][13][14].…”

Trends and Evolution of the GIS-Based Photovoltaic Potential Calculation

“…This is especially relevant when looking at groups of buildings; the impact that each building has on the others is taken into account-at this scale, other elements of disturbance, such as trees, can be included in the model-together with slope and orientation in order to define, among a restricted set of alternatives, the most profitable. In this group, all the papers considering this scale [25,27,28,32,49,59,72,74,77,82] focused on a university campus. However, the number of buildings in this category of papers ranges from two and three in [49,72], respectively, to tens in [32].…”

However, the number of buildings in this category of papers ranges from two and three in [49,72], respectively, to tens in [32]. This results in heterogeneous processing methods, with some studies being more similar to single-building studies and others closer to district-scale analyses.…”
