“…We also recommend the continuation of research on the harmonization of the structure of the hybrid model, which should affect the clarity of the visual message and the final aesthetics of the model. Taking into account the possibility of using different geovisualization techniques of terrain surfaces [86], this is an important aspect of end-use data. Assuming that the ideal data development process usually involves full automation, further research should address the problem of bathymetric surface modeling in close proximity to the coastline.…”

This paper presents a method for integrating data acquired by unmanned surface vehicles and unmanned aerial vehicles. The aim of this work was to create a uniform bathymetric surface extending to the shoreline. Such a body of water is usually characterized by ultra-shallow depths, which makes measurement impossible even with hydrographic autonomous vessels. Bathymetric data acquired by the photogrammetric method are, however, characterized by large errors with increasing depth. The presented method is based on processing of two data sets using a bathymetric reference surface and selection of points on the basis of generated masks. Numerical bathymetric models created by interpolation methods confirmed the usefulness of the concept adopted.

Virtual globes render planetary-scale terrain and have limited support for 3D applications development. Game engines provide development environment for interactive 3D applications development and have limited support for world-scale terrain rendering. The game engine based terrain rendering methods lacks hardware based tessellation for high-performance. This work presents a novel method for a high-performance large-scale terrain rendering for high-fidelity display systems using game engine. The proposed method performs patch-based hierarchical culling of a multi-resolution terrain model to reduce rendering load. A view-based algorithm simplifies the patches with error control on GPU. Simplified patches are efficiently submitted for drawing using indirect mesh instancing feature of game engine. The proposed method utilizes hardware tessellation feature for high-performance model tessellation and accurate earth's surface construction using displacement mapping. The proposed method is evaluated by rendering scenes for high-quality output on consumer-level hardware. Flights are performed with various settings and results are compared with clipmap-based and state-of-the-art hardware tessellation based adaptive methods. The proposed method achieved 750, 575, and 540 frames-per-second for HD, full-HD, and ultra-HD display resolutions.

“…Ruzinoor et al [9] had done an intensive review on online 3D terrain visualization. There are many type of experiments and testing that being done to test the effectiveness of this information such as using different type of web servers [10], GIS software [11], contour intervals [12], rendering techniques [13], and satellite imageries [14]. Besides that, by utilizing Virtual Reality Markup Language (VRML) technology, [15] also has been developed online 3D terrain visualization for oil palm plantation.…”

Oil palm industry has been the backbone for the growth of Malaysia economy. The exports of this commodity increasing almost every year. Therefore, there are many studies focusing on how to help this industry increased its productivity. In order to increase the productivity, the management of oil palm plantation need to be improved and strengthen. One of the solution in helping the oil palm manager is by implementing online 3D visualization technique for oil palm plantation using game engine technology. The potential of this application is that it can helps in fertilizer and irrigation management. For this reason, the aim of this paper is to investigate the issues in managing oil palm plantation from the view of oil palm manager by interview. The results from this interview will helps in identifying the suitable issues could be highlight in implementing online 3D visualization technique for oil palm plantation management.
