RESEARCH ARTICLE 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 derived 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 classroomand for research by experts and
non-experts including by students.
