Steps in Developing Standards for SAR Data

by Siri Jodha Khalsa, June 22, 2017

Developing Requirements

  1. Assemble an inventory of current and planned SAR missions, including both space and
    airborne instruments
  2. Determine what formats are currently in use
  3. Develop a data model for SAR data, i.e. what are the typical elements of a SAR data file
    and what essential metadata needs to accompany it to make it interpretable
  4. Create a list of features that a SAR file format should have, such as lossless internal
    compression, chunking, and perhaps the ability to stream the data when transferring it
    over the internet.

Vet requirements with community

  1. Determine best method of getting producer and user community input on requirements
    for SAR data. For example, an Open Geospatial Community Domain Working Group or
    a NASA Earth Science Data Systems Working Group. I’m looking for other suggestions
  2. Develop prototype files for testing and review

Begin formal development

  1. Do a trade study to determine the most suitable Standards Development Organization
    (IEEE-SA, OGC, ISO, etc.) to work with. Considerations include – organizational support,
    name recognition, cost to use the final standard, etc.
  2. Seek sponsorship of the effort (we have some seed funding from GRSS in 2017, but
    development typically takes more than 1 year)
  3. Initiate project
