Multiresolution reference model for digital earth

我们的工业合作伙伴，PYXIS创新公司，是数字地球软件的开发商，该软件可以模拟地球及其数据，称为世界观。数字地球是一个框架，它使用地球的数字表示作为地理空间数据集成、管理、可视化和处理的参考模型。这样一个框架有助于有效地获取地理综合信息，帮助广大公众了解地球和影响地球的问题并作出决定。**然而，地理空间数据集往往体积很大，并且具有许多不同级别的保真度。这对数字地球框架产生了重大影响，当我们希望对这些数据进行查询或在互联网上流式传输时，会产生许多挑战。此外，这些查询只有在通过一组自然的交互以一种可理解和引人入胜的方式可视化时才有意义。**在国家科学研究委员会研究中心的支持下，我们的研究团队将探索先进的计算和数学方法，以有效地处理和传输大量不同分辨率的地理空间数据。这些方法对于提高数字地球软件的性能是必不可少的。此外，研究团队将采用、定制和/或修改最近提出的交互式图形和可视化方法，以便创造性地可视化和与地理空间数据交互，并将这些技术结合起来解决几个实际用例。**加拿大幅员辽阔，自然资源丰富，地理空间数据处理和可视化方法的改进将使加拿大受益匪浅。特别是PYXIS创新公司的世界观，将有助于加拿大走向图形和地理信息系统软件开发的前沿。* * * * * *

Our industrial partner, PYXIS innovation, Inc., is a developer of Digital Earth software that models the Earth and its data, called WorldView. Digital Earth is a framework that uses a digital representation of Earth as a reference model for the integration, management, visualization and processing of geospatial data. Such a framework facilitates efficient access to geo-integrated information, helping the public at large to learn and make decisions about the Earth and the issues affecting it.** Geospatial data sets, however, tend to be large in volume and feature many different levels of fidelity. This has a significant impact on the Digital Earth framework, creating many challenges when we wish run queries on these data or stream them over the internet. Furthermore, these queries are only meaningful if their results are visualized in an understandable and engaging way through a natural set of interactions.** With the support of an NSERC CRD, our research team will explore advanced computational and mathematical methods to efficiently process and stream massive amounts of geospatial data at different resolutions. Such methods are essential for improving the performance of Digital Earth software. Additionally, the research team will employ, customize, and/or modify recently proposed methods from interactive graphics and visualization in order to creatively visualize and interact with geospatial data, and will combine these techniques to solve several practical use cases.**As a vast country with a substantial amount of natural resources, Canada stands to benefit greatly from improved geospatial data processing and visualization methods. PYXIS innovation's WorldView, in particular, will contribute to bringing Canada towards the forefront of graphics and GIS software development. ******
