Collaborative Research: Map Tools for EarthScope Science and Education

合作团队正在开发一套强大的交互式网络地图工具，用于研究和教育。这些工具可以近乎实时地访问EarthScope的数据和产品。该项目建立在几年来测绘工具的发展基础上，包括儒勒·凡尔纳旅行者，全球应变率图（www.world-strain-map.org）和地球范围旅行者工具。这些工具使地质、地球物理和地球动力学数据和模型为广大受众所访问。全球应变率图模型和档案正在根据每一组新的全球定位系统观测资料进行更新。目前正在为北美西部开发一个具体的高分辨率应变率和速度场图。研究小组还致力于开发用于教学和研究的有限应变动画。这些有限应变模拟主要受限于目前由EarthScope和其他GPS测量定义的瞬时应变率解。模拟考虑了侵蚀速率、地形均衡调整以及地壳增厚和变薄速率。利用小时间步长跟踪地形点。多个时间步骤结合在一起，提供了动画，可以很好地显示板块边界如何随着时间的推移而演变和可能演变。课程资源也正在开发中，为K-12和大学水平提供背景，使教育工作者能够利用地图工具和所呈现的内容进行教学。这个团队正在探索新的基于探究的互动课程模块，这些模块建立在地球观测的科学成果和技术资源之上。

The collaborative team is developing a powerful suite of interactive, web-based mapping tools for both research and education. These tools allow near-real-time access to EarthScope data and products. The project builds on several years of development of mapping tools, including the Jules Verne Voyager, Global Strain Rate Map (www.world-strain-map.org), and the EarthScope Voyager tool. These tools make geologic, geophysical, and geodynamic data and models accessible to a broad audience. The global strain rate map model and archive is being updated with each new set of Global Positioning System (GPS) observations that are made available. A specific high-resolution strain rate and velocity field map is being developed for western North America. The research team is also working to develop finite strain animations for both teaching and research. These finite strain simulations are constrained primarily by the instantaneous strain rate solutions now defined by EarthScope and other GPS measurements. Simulations take into account erosion rates, isostatic adjustment of topography, and crustal thickening and thinning rates. Topography points are tracked through time using small time steps. Multiple time steps are combined to provide animations that are excellent for displaying how the plate boundary has evolved, and might evolve, over time. Curricular resources are also being developed that provide the background for K-12 and university levels that will enable educators to utilize the map tools, and the content presented, for instruction. The team is exploring new inquiry-based, interactive curricular modules that build on EarthScope scientific results and technical resources.
