Satellite Needs Working Group (SNWG)

The Interagency Implementation and Advanced Concepts Team (IMPACT) Satellite Needs Working Group (SNWG) works in coordination with the larger SNWG initiative of the U.S. Group on Earth Observations. The SNWG team serves as a data liaison for NASA’s Earth Science Data and Information Systems (ESDIS) project.

The primary point of interface for the SNWG team is the biennial agency survey. The biennial agency survey is issued to identify potential data gaps in the current NASA program of record and/or data sets that meet agency needs. Currently, the IMPACT SNWG project team is supporting NASA headquarters to complete the 2018 survey assessment by identifying data sets and providing analysis relevant to agency needs.

Interagency Support

One of the primary tasks for the SNWG team is to serve as a single point of contact between external federal agencies and NASA. Agency support is provided through the development of two platforms. The first is an archive of agency survey responses and NASA assessments which supports future biennial surveys, identifies agency data continuity concerns, and uncovers potential data gaps in the NASA program of record. The second is a web platform that allows end users to query existing databases for datasets relevant to their particular agency need. Both platforms are developed with the intention of providing external agencies with resources to address their needs between biennial surveys.

Uncovering Data Gaps

The SNWG gathers and analyzes the Earth observation data needs of various U.S. government agencies. Through uncovering and communicating existing and future data gaps to NASA, the SNWG project team works to better inform current and future mission decisions. Data continuity is a primary concern for participating SNWG agencies; thus, the platforms developed to support participating agencies discussed above address these needs. The inclusion of data continuity information not only allows users to analyze temporal trends within similar data sources, it also allows potential future data gaps to be identified for mission planning. Such planning is critically important to the operational needs of participating agencies.
