SDAT	The Spatial Data Access Tool (SDAT) is a web-based tool that enables users to visualize biogeochemical data sets in Google Earth, explore metadata, or customize and download data by specifying projection, resolution, format, spatial extent, time period, band(s), and interpolation method.	ORNL DAAC
SOTO	State of the Ocean (SOTO) provides near real-time data that are displayed in a Google Earth environment and annotated to give context descriptions of the ocean's features and events using KML overlays (ice extent, hurricane tracks, clouds). It provides data layers for satellite derived sea surface temperature and anomalies, sea surface height anomalies, wind vectors, and ocean color.	PO.DAAC
TES Search and Subset Tool	This tool enables a more sophisticated approach to selecting and ordering Tropospheric Emission Spectrometer (TES) global survey standard data by date, time and geolocation. Data products can be subset by parameter and geolocation. Output can be requested in HDF-EOS or netCDF.	ASDC
Worldview	NASA's Worldview data visualization application provides the capability to interactively browse more than 1,000 global, full-resolution satellite imagery layers and then download the underlying data. Many of the available imagery layers are updated within three hours of observation, which supports time-critical application areas such as wildfire management, air quality measurements, and flood monitoring. Imagery in Worldview is provided through NASA's Global Imagery Browse Services (GIBS). Worldview also includes nine geostationary imagery layers from the GOES-East, GOES-West, and Himawari-8 geostationary satellites that is available at 10-minute increments for the last 30 days. These layers include Red Visible, which can be used for analyzing daytime clouds, fog, insolation, and winds; Clean Infrared, which provides cloud top temperature and information about precipitation; and Air Mass RGB, which enables visualization of specific air mass types (e.g., dry air, moist air, etc.). These full disk hemispheric views allow for almost real-time viewing of changes occurring around most of the world.	Cross DAAC
WPT	The Waypoint Planning Tool (WPT) is a Java application used to specify aircraft flight tracks through an interactive point-and-click interface. Individual flight legs are automatically calculated for altitude, latitude, longitude, leg distance, cumulative distance, leg time, cumulative time, etc. The resultant flight plan can then be posted to the Google Earth-based RTMM for all interested scientists to view and track actual flight progress compared to the planned flight track.
