The complexity of interrelationships between urban natural environments and human environments is increasing with rapid urbanization. This brings new challenges to urban modeling and simulation in simultaneously meeting the comprehensive needs of the dual integration of data and models, multi-type visualizations, human-centered simulation, geographic collaboration, and interactions between physical and virtual spaces. We here propose virtual geographic environments (VGEs) as a new platform of urban modeling and simulation. After discussing the evolution, definition, and features of VGEs, we design a VGE framework for urban system modeling and simulation. Two typical cases are provided to illustrate how VGEs support urban modeling and simulation on different scales: VGE-based collaborative modeling and the simulation of air pollution dispersion in the Pearl River Delta (PRD) urban agglomeration, and fire emergency crowd evacuation simulation. In the future, VGEs may also play an important role in digital twin cities and urban metaverses.

“…(1) According to the selected forest management measures, such as thinning and shelterwood cutting, the decision-making model for felling trees can calculate the felling probability of individual trees . (2) The individual-tree information estimation model can calculate individual-tree locations and DBHs based on forest stand attributes (e.g., mean DBH and dominant DBH) and the spatial distribution of the trees; thus, it can perform estimates from forest stand data to individual-tree data (Li et al, 2013;Tang et al, 2018).…”

“…Several systems and frameworks have been developed that can integrate models for forest growth modeling and simulation. SIMO (Rasinmäki et al, 2009), OntoPlant (Tang et al, 2011;Tang et al, 2018), sIMfLOR (Faias et al, 2012), CAPSIS (Dufour-Kowalski et al, 2012) and DSS-SADfLOR (Garcia-Gonzalo et al, 2014) are notable examples. The OntoPlant software package can combine different individual-tree models to simulate the growth of the tree height, diameter and the number of branch whorls.…”

To facilitate forest research, simulations of the whole forest growth process can be employed to analyze forest dynamics and predict forest yields. Different forest growth models can be integrated for comprehensive process simulation and thus can assist forest growth research. With the development of network technologies, a web environment can provide cross-platform capability and wide availability for distributed researchers. In order to serve the simulation of complex forest growth processes and help online forest growth research, this article proposes a web-based integrated modeling and simulation method for forest growth research. The proposed method includes three steps, namely, model preparation, model integration, and forest growth simulation. The corresponding implementation strategies are designed to prepare forest growth models, integrate different models, preprocess model data, and implement forest growth simulations for integrated modeling and simulations via the web. Two applications in the comprehensive prediction of forest growth and comparison of different forest management decisions are introduced to verify the feasibility and capability of the proposed method. The results show that the proposed web-based integrated modeling and simulation method can be used conveniently for comprehensive simulations of forest growth research.

“…This technique can simulate the operation of the power system, including various fault and disturbance conditions, thus helping power system engineers to better understand the operation and problems of the power system. The literature [13] proposed a 3D forest growth simulation technique based on a virtual geographic environment, which can simulate the growth and evolution process of a forest in a virtual geographic environment, including the effects of vegetation growth, soil moisture, light, and other factors. This technique can be implemented by computer simulation, avoiding the cost and risk of practical operation.…”

Based on the virtual simulation platform, this paper firstly builds a five-in-one comprehensive, realistic 3D virtual platform with teaching method orientation, experiment method frontier, course thinking daily, team building refinement, and assessment and evaluation comprehensiveness. Then the establishment of the UAV nonlinear mathematical model, the bit attitude calibration of the UAV model, the virtual simulation of the motion of the UAV model, and the construction of the UAV flight sky realistic model based on the UAV corner control of virtual reality technology, and also the analysis of the UAV formation keeping control research based on 3D virtual simulation. The results show that the UAV takes off from a random initial position, so the initial error is large, and then the formation holding error is less than 0.1m when flying in a straight line, and the formation error is less than 1.79 when coordinating a turn. When flying in formation for the 40s, the ground sends a formation spreading command to perform a reconnaissance mission, and this study has a catalytic effect on the development of UAV aerial photography virtual simulation.
