“…However, the projection of the input polyline may not always be the same as the one adopted in the original data source. For example, the polyline retrieved using the API was provided by Cesium is WGS (World Geodetic System) 84 [55], while the data used for our study is an azimuthal equidistant projection [56]. In this case, a re-projection process is required before rasterization.…”

Abstract:The world is undergoing rapid changes in its climate, environment, and ecosystems due to increasing population growth, urbanization, and industrialization. Numerical simulation is becoming an important vehicle to enhance the understanding of these changes and their impacts, with regional and global simulation models producing vast amounts of data. Comprehending these multidimensional data and fostering collaborative scientific discovery requires the development of new visualization techniques. In this paper, we present a cyberinfrastructure solution-PolarGlobe-that enables comprehensive analysis and collaboration. PolarGlobe is implemented upon an emerging web graphics library, WebGL, and an open source virtual globe system Cesium, which has the ability to map spatial data onto a virtual Earth. We have also integrated volume rendering techniques, value and spatial filters, and vertical profile visualization to improve rendered images and support a comprehensive exploration of multi-dimensional spatial data. In this study, the climate simulation dataset produced by the extended polar version of the well-known Weather Research and Forecasting Model (WRF) is used to test the proposed techniques. PolarGlobe is also easily extendable to enable data visualization for other Earth Science domains, such as oceanography, weather, or geology.

“…For these maps it is also possible to choose different the distances to the center. One use was to let British colonials know in which direction to point their radio antennas to receive a signal sent from Rugby in the U.K (Hinks, 1929;Reeves, 1929). These unusual projections generally contain a hole inside of the map and a portion of the area overlaps itself (Tobler, 2002).…”
