Improving Access to Geodetic Imaging Crustal Deformation Data Using GeoGateway

GeoGateway (http://geo-gateway.org) is a web-based interface for analysis and modeling of geodetic imaging data and to support response to related disasters. Geodetic imaging data product currently supported by GeoGateway include Global Navigation Satellite System (GNSS) daily position time series and derive velocities and displacements and airborne Interferometric Synthetic Aperture Radar (InSAR) from NASA’s UAVSAR platform. GeoGateway allows users to layer data products in a web map interface and extract information from various tools. Extracted products can be downloaded for further analysis. GeoGateway includes overlays of California fault traces, seismicity from user selected search parameters, and user supplied map files. GeoGateway also provides earthquake nowcasts and hazard maps as well as products created for related response to natural disasters. A user guide is present in the GeoGateway interface. The GeoGateway development team is also growing the user base through workshops, webinars, and video tutorials. GeoGateway is used in the classroom and for research by experts and non-experts including by students.

GeoGateway（网址：http://geo-gateway.org）是一款基于网页的交互界面，可用于大地测量成像数据的分析与建模，并为相关灾害响应工作提供支持。目前GeoGateway支持的大地测量成像数据产品包括全球导航卫星系统（Global Navigation Satellite System, GNSS）单日位置时间序列、衍生的速度与位移数据，以及来自美国国家航空航天局（National Aeronautics and Space Administration, NASA）UAVSAR平台的机载干涉合成孔径雷达（Interferometric Synthetic Aperture Radar, InSAR）数据。GeoGateway允许用户在网页地图界面中叠加各类数据产品，并通过多种工具提取信息，提取得到的产品可下载以供后续分析使用。GeoGateway内置了加利福尼亚州断层迹线叠加层、基于用户选定搜索参数生成的地震活动性数据，以及用户上传的地图文件。该平台还可提供地震即时预报、灾害风险图，以及为自然灾害应对工作定制的各类数据产品。GeoGateway界面中附带了用户指南。GeoGateway开发团队还通过举办研讨会、网络研讨会及视频教程来扩大用户群体。目前，GeoGateway已被应用于课堂教学与科研工作，使用者涵盖专业人士与非专业人士，包括在校学生。
