科学网关提供了对特定于领域的工具和数据的轻松访问。地理信息科学与系统（GIS）领域使用了大量的工具和数据集，这给设计科学门户以满足用户不同的研究和教学需求提出了挑战。我们描述了一个新的科学门户，称为GISandbox，旨在满足研究人员和教育工作者利用地理空间计算的需求，这是地理信息系统和计算科学的联系。GISandbox建立在Jupyter Notebooks上，为地理空间计算创建一个简单、开放和灵活的平台。Jupyter Notebooks是一个广泛使用的交互式计算环境，运行在浏览器中，集成了实时代码、叙述、方程和图像。我们扩展了Jupyter Notebook平台，使用户能够在云资源Jetstream上运行交互式笔记本，或者在位于匹兹堡超级计算中心的Bridges超级计算机上运行计算密集型笔记本。一个新颖的作业管理平台允许用户轻松地提交Jupyter Notebook，以便在bridge（最终是Comet）上批量执行、监视SLURM作业和检索输出文件。GISandbox虚拟机是在Jetstream的Atmosphere界面中创建的，然后使用一系列的Ansible脚本进行部署和配置，这使我们能够创建一个易于复制和可扩展的系统。本文概述了我们对GISandbox的愿景，当前的实现，并讨论了展望未来以及GISandbox如何在其他领域中使用。
Science gateways provide easy access to domain-specific tools and data. The field of Geographic Information Science and Systems (GIS) uses myriad tools and datasets, which raises challenges in designing a science gateway to meet users' diverse research and teaching needs. We describe a new science gateway called the GISandbox that is designed meet the needs of researchers and educators leveraging geospatial computing, which is situated at the nexus of GIS and computational science. The GISandbox is built on Jupyter Notebooks to create an easy, open, and flexible platform for geospatial computing. Jupyter Notebooks is a widely used interactive computing environment running in the browser that integrates live code, narrative, equations and images. We extend the Jupyter Notebook platform to enable users to run interactive notebooks on the cloud resource Jetstream or computationally-intensive notebooks on the Bridges supercomputer located at the Pittsburgh Supercomputing Center. A novel Job Management platform allows the user to easily submit a Jupyter Notebook for batch execution on Bridges (and eventually Comet), monitor the SLURM job, and retrieve output files. GISandbox Virtual Machines are created in Jetstream's Atmosphere interface and then deployed and configured using a series of Ansible scripts, which allow us to create an easily reproducible and scalable system. This paper outlines our vision for GISandbox, the current implementation, with a discussion looking toward the future and how the GISandbox could be used in other domains.
