Ecotourism is a sustainable, green and smokeless industry of the society by providing alternative source to the livelihood and local community, in order to re-naturalize the environment to bring the man closer to the natural environment. The use of web application has changed the way tourists gather information about tourist attraction spots of the research area. The aim of the study is to assess and identify ecotourism attraction sites of Chokie Mountain watersheds for touristic activities to develop a web-based GIS mapping portal for the improvement of nature-based ecotourism activities. The web-based GIS portal for Web Mapping Application is available for the user with the skills necessary to create standard web mapping services. We have implemented web mapping services based on formal cartographic visualization rules in the open source QGIS software and threejs JavaScript plugin. Threejs plugin is used for 3D visualization, interaction and export terrain data, map canvas image and vector data to HTML page and JS. The result of web-based GIS portal supports spatial and non-spatial database of tourist attraction and tourist service data with attractive user interface.

“…Web technologies that can provide VR are, for example, Three.js (Herman et al, 2017;Juřík et al, 2018), X3DOM (Herman and Řezník, 2015;Herman and Russnák, 2016) or WebVR. The advantage of web technologies is the fact that there is no need to install any new software application.…”

“…These headsets, and VR in general, are currently used for many different purposes and in various applications, including archaeology (Chmelík and Jurda, 2017;Liarokapis et al, 2017), architecture (Portman et al, 2015), medicine (Li et al, 2017), engineering and design (Coburn et al, 2017), education (Kovalčík et al, 2012;Juřík et al, 2016;Moskal and Choate, 2017), the game industry (Shepherd and Bleasdale-Shepherd, 2009;Chądzyńska and Gotlib, 2015), etc. The use of VR has also increased in geosciences, for example in spatial and urban planning (Herbert and Chen, 2015;Portman et al, 2015), crisis management (Kubíček et al, 2011;Bandrova et al, 2012;Herman et al, 2017), noise mapping (Herman and Řezník, 2015), teaching geography (Stojšić et al, 2016;Carbonell and Saorín, 2017), cartography (Juřík et al, 2017;Kubíček et al, 2017) and geoinformatics (Řezník, 2013;Li et al, 2015).…”

<p><strong>Abstract.</strong> In this paper, we analysed and tested the possibilities for the use of low-cost VR (Virtual Reality) headsets, with a focus on cartographic visualization. Low-cost devices were compared and classified into three categories (low-end, mid-range and high-end). We also created a pilot virtual environment, called “Carthoreality”, and conducted simple pilot user testing using this virtual environment and the three low-end headsets. Our pilot test shows a few drawbacks to these devices, including weight of the headset and penetrating light. Some problems in terms of user aspects were also identified, such as nausea while wearing headsets or disorientation after removing them, which occurred for all users.</p>

“…3D tiles represent 3D spatial content including buildings, trees, point clouds, and vector data with built‐in models, which can provide efficient 3D visualization (Chen, Shooraj, Rajabifard, & Sabri, 2018; Gan, Li, & Jing, 2017; Haje, Jessel, Gaildrat, & Sanza, 2016; Kulawiak, 2016; Kulawiak & Kulawiak, 2017). With the success of 3D tile applications, recent studies started to modify and extend the built‐in data models based on its open specifications in different fields, for example, the visual display of flood data (Herman, Russnák, & Řezník, 2017) and the optimization of the 3D tiles data format (Song & Li, 2018). Although there are many studies on 3D tiles, to the best of our knowledge, no researchers have attempted to use 3D tiles to visualize large‐scale weather radar data in a real‐time manner.…”

Weather radar data play an important role in meteorological analysis and forecasting. In particular, web‐based real‐time 3D visualization will enable and enhance various meteorological applications by avoiding the dissemination of a large amount of data over the internet. Despite that, most existing studies are either limited to 2D or small‐scale data analytics due to methodological limitations. This article proposes a new framework to enable web‐based real‐time 3D visualization of large‐scale weather radar data using 3D tiles and WebGIS technology. The 3D tiles technology is an open specification for online streaming massive heterogeneous 3D geospatial datasets, which is designed to improve rendering performance and reduce memory consumption. First, the weather radar data from multiple single‐radar sites across a large coverage area are organized into a spliced grid data (i.e., weather radar composing data, WRCD). Next, the WRCD is converted into a widely used 3D tile data structure in four steps: data preprocessing, data indexing, data transformation, and 3D tile generation. Last, to validate the feasibility of the proposed strategy, a prototype, namely Meteo3D at https://202.195.237.252:82, is implemented to accommodate the WRCD collected from all the weather radar sites over the whole of China. The results show that near real‐time and accurate visualization for the monitoring and early warning of strong convective weather can be achieved.
