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，该软件模拟地球及其数据，称为WorldView。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的整合、管理、可视化和处理的参考模型。这样的框架有助于有效获取地理综合信息，帮助广大公众了解地球及其影响地球的问题并做出决策。 然而，地理空间数据集往往体积庞大，具有许多不同程度的保真度。这对数字地球框架产生了重大影响，当我们希望在这些数据上运行查询或在互联网上流式传输时，会产生许多挑战。此外，这些查询只有在其结果通过一组自然的交互以可理解和吸引人的方式可视化时才有意义。 在NSERC CRD的支持下，我们的研究团队将探索先进的计算和数学方法，以有效地处理和流式传输不同分辨率的大量地理空间数据。这些方法对于提高数字地球软件的性能至关重要。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，以创造性地可视化和与地理空间数据交互，并将联合收割机结合这些技术来解决几个实际用例。 作为一个拥有大量自然资源的大国，加拿大将从改进的地理空间数据处理和可视化方法中受益匪浅。特别是PYXIS创新的WorldView将有助于将加拿大推向图形和GIS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.
