The Prediction Of Worldwide Energy Resources (POWER) is a geographic information system (GIS)-enabled interactive web portal that provides data products customized to three primary user communities: Renewable Energy, Sustainable Buildings, and Agroclimatology. These products are available from daily up to multiple-year averages.
R is a software language and environment for statistical computing and graphics. R is designed around a true computer language, and it allows users to add additional functionality by defining new functions. R is available as Free Software in source code form. It compiles and runs on a wide variety of UNIX platforms and similar systems (including FreeBSD and Linux), Windows, and MacOS.
The SeaWiFS Bio-optical Archive and Storage System (SeaBASS) Search application enables users to discover data in the publicly shared archive of in situ oceanographic and atmospheric data maintained by NASA’s Ocean Biology Processing Group (OBPG).
NASA's Sea-viewing Wide Field-of-view Sensor (SeaWiFS) Data Analysis System (SeaDAS) is a comprehensive software package for the processing, display, analysis, and quality control of ocean color data. While the primary focus of SeaDAS is ocean color data, it is applicable to many satellite-based earth science data analyses.
SEDAC's POPGRID Viewer enables direct comparison of different population datasets based on different data sources and methodologies. The tool incorporates a four-panel display of six different data sets, including Gridded Population of the World, Landscan, WorldPop, and Human Settlements Population Grid.
SEDAC's Population Estimation Service is a web-based service that lets users of a wide variety of map clients and tools quickly obtain estimates of the number of people residing in a user-defined geographic region, without having to download and analyze large amounts of spatial data.
The Soil Moisture Visualizer, developed by NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC), is a tool that integrates a variety of different soil moisture datasets over North America. The visualization tool incorporates in-situ, airborne, and remote sensing data into one easy-to-use platform.
The Spatial Data Access Tool (SDAT), developed by NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC), is an Open Geospatial Consortium (OGC) standards-based web application to visualize and download spatial data in various user-selected spatial/temporal extents, file formats, and projections. Datasets including land cover, biophysical properties, elevation, and selected ORNL DAAC archived data are available through SDAT.
A protocol defines a set of rules used by two or more parties to interact between themselves. A standard is a formalized protocol accepted by most of the parties that implement it. Not all protocols are standards (some are proprietary). Not all standards are protocols (some govern other layers than communication).
State of the Ocean (SOTO), developed by NASA's Pysical Oceanography Distributed Active Archive Center (PO.DAAC), is an interactive web-based tool that generates informative maps, animations, and plots that communicate and prove the discovery and analysis of the state of the oceans.
The Surface Water and Ocean Topography (SWOT) Swath Visualizer provides a visualization of two instruments’ coverage of Earth's surface: the Ka-band Radar Interferometer (KaRIn) and altimeter. Users can search for places of interest to obtain swath information.
Synthetic aperture radar, or SAR, uses the microwave region of the electromagnetic spectrum. SAR can penetrate cloud cover and “see through” darkness and weather, allowing a unique view of flood inundation, land cover changes, and modifications of Earth’s surface from landslides, earthquakes, and background tectonic motion. NASA’s home for SAR data and imagery is the Alaska Satellite Facility Distributed Active Archive Center (ASF DAAC).
