Welcome to GPS Explorer
NOTICE CONCERNING DISPLAY OF TIME SERIES PLOTS:
PC Users: Mozilla Firefox browser (starting with version 52) no longer supports plugins, including the GPS Explorer time series Java applet. One option is to install 32-bit Mozilla Firefox version 51.0.1 or lower and 32-bit Oracle Java on a PC. You'll need to turn off automatic Firefox updates. A better option is to use Internet Explorer browser version 11. In any case, you need to add the GPS Explorer url in your Java Control Panel's Exception Site List under the Security tab: http://geoapp03.ucsd.edu/gridsphere/gridsphere?cid=Time+Series+Plots Mac Users: You can use Chrome, Safari and Firefox 52.2.0 (ESR). Note: There is a problem accessing the Model Terms for MAC users. We are trying to fix this.
Introduction The GPS Explorer data portal provides tools to access and explore GPS data, positions, time series, velocities, and strain from continuous GPS stations covering Western North America and around the globe. These data products are generated as part of a NASA MEaSUREs project (see background below), and are updated weekly. GPS Explorer contains interactive utilities for selecting sites, displaying time series, and mapping velocities. Products such as velocities can be viewed at user-specified scales, with complementary data sets such as recent seismic activity. Options for map layers (e.g., terrain/satellite base layers, toggling fault lines) are also available.
Getting Started Please log in or create an account via the "Login" window to the right. An account enables user settings such as map state, site groups, and modeling jobs to be saved for subsequent visits.
About GPS Explorer Data Products SOPAC GLOBK and JPL GIPSY data are combined to create the MEaSUREs combination using the JPL analyze_tserist_filter software package. Products are available via individual applications under the "Data Products" tab once logged in, or from the lists below. Official products are listed in the ESDR table below. Products are produced in the ITRF2014 reference frame.
Data Product Table Solid Earth Science ESDR System - Algorithm Theoretical Basis Document ![]() Project Background This project is funded through the NASA MEaSUREs program. Building on NASA's investment in the measurement of crustal deformation from continuous GPS (CGPS) networks, GPS Explorer is part of our Science Data System (SDS) to provide mature, long-term Earth Science Data Records (ESDRs) that support NASA's Earth Surface and Interiors (ESI) focus area. GPS Explorer represents the web interface of the project's cyberinfrastructure. We have built upon open GIS standards, particularly those of the Open GIS Consortium (OGC), and have used the principles of Web Service-based Service Oriented Architectures to provide scalability and extensibility for new services and capabilities.
If your use of these data products results in a publication, please cite "Bock, Y. and F.H. Webb 2012. MEaSUREs Solid Earth Science ESDR System. La Jolla, California and Pasadena, California USA: [list archive from which data were obtained], [list dates of data used]. Digital media." and notify us of your publication.
