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.

该合作团队正在开发一套功能强大的交互式、基于网络的测绘工具，用于研究和教育。 这些工具使人们能够接近实时地获取地球观测数据和产品。该项目建立在多年来开发的制图工具的基础上，包括儒勒·凡尔纳航海家号、全球应变率地图（www.world-strain-map.org）和EarthScope Voyager工具。这些工具使广大受众能够访问地质、地球物理和地球动力学数据和模型。全球应变率图模型和档案正在根据提供的每一套新的全球定位系统观测数据进行更新。目前正在为北美西部绘制一幅具体的高分辨率应变率和速度场图。研究团队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EarthScope和其他GPS测量定义的瞬时应变率解的约束。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。使用小的时间步长通过时间跟踪地形点。多个时间步长相结合，以提供动画，是优秀的显示如何板块边界的演变，并可能演变，随着时间的推移。还正在开发课程资源，为K-12和大学提供背景，使教育工作者能够利用地图工具和所提供的内容进行教学。该小组正在探索以地球观测科学成果和技术资源为基础的新的以调查为基础的互动课程模块。
