Data Access and Visualization Tools

General Requirements

  • Help / Reference materials, including Quick Start Guide
  • stable platform (e.g. toolset expected to be around and supported for awhile)
  • provides centralized access to MMS data products
  • capable of reading CDF files
  • displays line plots (1 variable vs. time, multiple variables vs time, 1 variable against 2 variables where color or contour plots are used to indicate the 3rd variable)
  • displays spectrograms
  • displays cross hair value indicator
  • coordinate transformations
  • flexible customization support to support additional capabilities as needed (e.g. plugins)
  • offline data storage in standard format
  • orbit annotations on data
  • panning (continuous panning is a nice-to-have)
  • data selection
  • save / load queries to facilitate common tasks
  • capable of displaying time periods of interest (e.g. highlight time periods that might have been selected for downlink)
  • user community should be free to modify the tool
  • Notes:
    • Access and visualization needs DO NOT need to be consolidated into a single tool.  Multiple tools OK.
    • There are NO restrictions on the language used (e.g. IDL is OK even though it may require users to purchase licenses, C++ is OK even though it would need to be compiled).

Requirements that are specific to Level-2/3;

  • supports drilling down to higher time resolution data to millisecond resolution
  • 3-d visualization (nice-to-have or requirement?)
  • standard outputs in publication quality
  • custom fonts and styles

Requirements that are specific to SITL:

  • displays Burst Quality Indicators (e.g. CDQ, MDQ, FOM)
  • displays TDNs
  • nice-to-have: capable of displaying multiple linked windows
  • will accept input regarding buffer selections (e.g. time periods, FOM, etc)
  • capable of displaying system responses (e.g. warnings, selection status, etc from the SOC)
  • capable of supporting authentication for accepting Designated SITL input (note that this could potentially be handled via an Internet form submission rather than integrated into the SITL access and visualization tool)
  • supports drilling down to higher time resolution data to 10-second resolution

Next Steps:

  • look into development and maintenance costs
  • look into stability of various options (e.g. expected future development/support of each option and its dependencies)
  • define specific requirements for on-the-fly flexibility
  • hands-on workshops for tool options
  • look into compression capabilities of realistic sample data in CDF file format
  • research and test server-based SITL options

Existing Options:

  • No labels
