Item Towards a 3D GIS for Underground Infrastructure(The Eurographics Association, 2016) Soria, Gregorio; Ortega, Lidia; Feito, Francisco R.; Alejandro Garcia-Alonso and Belen MasiaThe use of advanced software tools for groundwater management is essential to carry out the management of these underground infrastructure. Tools capable of accomplishing these processes are the so-called 3D GIS. However, these systems are not widely implemented, mainly because of their complexity. In this paper we present the data model of an underground infrastructure for city sanitation management. It discusses the design of the database, the acquisition and processing of such information, as well as the visualization and interaction with the resulting model.Item A 3DWeb Application for Weather Forecast Based on WebGL(The Eurographics Association, 2015) Graciano, Alejandro; Rueda, Antonio J.; Feito, Francisco R.; MartÃnez, Francisco; Mateu Sbert and Jorge Lopez-MorenoManagement, interpretation and visualization of geoscientific and atmospherical information is a major problem for the geoscientist and for a correct diffusion, due to its high volume, complexity, spatiotemporal dimension and three-dimensional nature. As a result, development of software tools for integration, exploration and graphical analysis of the growing amount of available geodata is of great importance. In the last decade a trend towards the implementation of these tools as web applications has consolidated because of its benefits: universal access, permanent availability and ease of collaborative use. However until recently Web development technologies have been ill-equipped for implementing interactive 2D and 3D applications dealing with large amounts of data as required by many geoscience applications. The support of WebGL by most modern browsers has changed this situation and promises to revolutionize the Web in the next few years with a new generation of visually appealing, high performance interactive applications. In this work we describe the technologies for 3D Web and their use in the context of atmospherical data using a 3D weather information application as case study.Item 3D GIS Based on WebGL for the Management of Underground Utilities(The Eurographics Association, 2017) Jurado, Juan Manuel; Ortega, Lidia; Feito, Francisco R.; Fco. Javier Melero and Nuria PelechanoThis work summarizes a web application related to a research project about underground infrastructures. The aim is to visualize, analyse and manage all underground layers inside 3D urban environments. This is possible using WebGL to develop a web application which may be used from mobile devices. The study of terrain relief to calculate the depth of these infrestructures, the conversion of 2D data to 3D models, the definition of a spatial database and the use of virtual reality to visualize the resulting 3D scene make of this application a useful tool for utility companies dealing with underground infrastructures.Item Industrial Facility Modeling Using Procedural Methods(The Eurographics Association, 2015) Bishop, M. Scott; Max, Nelson; Mateu Sbert and Jorge Lopez-MorenoWe present an end-to-end system for procedurally modeling an industrial facility. The system is a collection of utilities that work together to assemble, lay out, and model a typical industrial facility (e.g. a wastewater treatment plant). A plug-in to the CityEngine (R) procedural modeling application was built in Java (TM) using an open-source framework. The plug-in provides the interface to access the facility assembly and layout engines, the facility rule file and Python script generators, and the OBJ footprint exporter. The system provides functionality for placing the facility model into an existing 3D scene using an established facility location algorithm that maximizes the minimum distance from existing structures in the scene.
