Software

UNAVCO promotes research and learning in geodesy by providing a variety of software, including web applications, and desktop utilities for scientists, instructors, students, and others. Web-based data visualization and mapping tools provide users with the ability to view post–processed data while web-based geodetic utilities provide ancillary information. Downloadable stand-alone software utilities include applications for configuring instruments, managing data collection, download and transfer, and performing computations on the raw data, e.g., data pre-processing or processing. A prime example of data pre-processing software is TEQC (Translate Edit Quality Check).

Mapping Tools

Mapping tools and datasets are available through UNAVCO, to assist all levels of users. These tools allow users to display data for full or subsets of datasets in a variety of ways.

• Mapping clients and tools allow users to see and analyze data geographically.... →
  • UNAVCO GPS Velocity Viewer web tool.
  • GEON Integrated Data Viewer downloadable application.
  • Jules Verne Voyager web tools.
• Google Earth KMZ datasets. ... →
  • GPS/GNSS monuments with data in the UNAVCO Archive including both Permanent Stations and Campaign Sites.
  • Education-oriented Geophysics datasets compilation including tectonic plates, plate motion, earthquakes, and more.
  • PBO Network Velocity and Status.
  • EarthScope Airborne LiDAR Hillshades.
• Network Monitoring / State of Health Maps allow users to get a snap-shot of the operational status of multiple instruments in a network in a map view.
  • UNAVCO GPS Remote Polar Stations, Network Operations Map
  • PBO GPS Station Health and Locations Map
  • PBO Strainmeter Health and Locations Map
  • PBO Seismic Stations Health and Locations Map

GPS/GNSS Data Collection, Download, and Transfer

UNAVCO provides a variety of software to aid investigators in data collection, download, and transfer. This software manages data on an instrument, offloads data from the instrument’s internal memory, and ensures that data arrive to destinations other than the initial download computer.

• Allen Osborne Receivers
• Ashtech Receivers
• Trimble Receivers
• General Tools and Data Loggers

Visualization Tools

To assist all levels of users, visualization tools are available through UNAVCO. These applications allow users to display data for individual or small groups of data points in a variety of ways.

• Time series plotting tools allow users to see and analyze data geographically. ... →
  • Data Archive Plotter graphs North, East, and Vertical GPS/GNSS positions over time and provides station event information. It also allows the viewing of multiple time series with shared axes.
  • PBO GPS Interactive Plotting Tool graphs the North, East, or Vertical position, state of health, and quality control parameters of a PBO station over time.
  • Borehole Strainmeter and Pore Pressure Interactive Plotting Tool graphs strain, pore pressure and other parameters over time.
• SAFOD Core Viewer supports viewing rock core extracted from the seismogenic zone of the San Andreas Fault Observatory at Depth.

GPS/GNSS Data Processing

Investigators can access either raw or processed data. For data that can not be used in its raw state, processing, and in many cases preprocessing, is required.

• Data pre-processing may be required to reformat, translate, remove extraneous data, and/or perform quality checks prior to processing the data.
  • TEQC (Translation, Editing and Quality Checking)
  • Formatting and other pre-processing tools explained.
• Data processing software performs computations on raw data, resulting in numeric representation of the physical parameters measured by the instrument.
  • Gipsy - JPL’sprocessing package.
  • GAMIT - MIT’s processing package.
  • Bernese GPS processing software

Geodetic Utilities

Geodesy utilities provide relevant information to support studies using any of the geodetic data types.

• Plate motion calculator is an online tool that calculates rigid plate motions ... →at a specified location on Earth using one or more plate.
• Geoid height calculator is an online tool that calculates a geoid height correction at a specified location on Earth using one or more gravity model.
