NASA LANCE Customer Satisfaction Survey


NASA would like to hear from its customers about the services that provide near real-time (NRT) data and imagery through the Land, Atmosphere Near real-time Capability for EOS (LANCE), a service of the NASA Earth Observing System Data and Information System (EOSDIS).

Through LANCE, NASA EOSDIS provides data and imagery from 10 instruments*.
- NRT data are made available through HTTPS and the Earthdata Search
- NRT imagery are made available through GIBS, Worldview and Worldview Snapshots
- Active fire/hotspots are made available through FIRMS.

Here are some definitions for LANCE, Worldview, Worldview Snapshots, Rapid Response, GIBS and FIRMS.
  • LANCE is a virtual system that provides data and imagery within 3 hours of satellite overpass to meet the timely needs of applications such as numerical weather and climate prediction, forecasting and monitoring natural hazards, ecological/invasive species, agriculture, and air quality
  • GIBS, the Global Imagery Browse Services, receives NRT imagery from LANCE (and other NASA sources) and makes it available to Worldview and other clients
  • Worldview is a client that enables users to view NASA imagery - both NRT and standard quality imagery
  • Worldview Snapshots is the replacement for Rapid Response subsets. It is a low band-width client that enables users to download imagery of their area of interest
  • FIRMS, the Fire Information for Resource Management System - is a component part of LANCE that provides active fire/hotspot data in a dedicated map viewer, web services, email alerts and SHP, TXT and KML files
  • Rapid Response was the precursor to Worldview, Worldview Snapshots and GIBS. The Rapid Response (orbit) Swath images are still available for MODIS, VIIRS (S-NPP) and VIIRS (JPSS-1/NOAA-20). They are likely to be replaced in winter 2020
The survey should take approximately 10 to 15 minutes to complete. All submitted information is collected and processed by CFI Group, an independent research and consulting firm. When you finish the survey, your responses will be sent directly to a database located on CFI Group's server, which cannot be accessed through any NASA online system.

Your opinions are very important. Your responses will remain anonymous and will only be reported in aggregate. If at any time you do not feel comfortable answering a question, you may choose not to answer. This survey is authorized by Office of Management and Budget Control No. 1090-0007, which expires on September 30, 2021.
