Data Pathfinders

Data Pathfinders guide users through the process of selecting application-specific datasets and learning how to use them through intuitive tools, facilitating equal and open access to the breadth of NASA Earth science data. The pathfinders are intended to familiarize users with and provide direct links to the applicable, commonly-used datasets across NASA’s Earth science data collections. After getting started here, there are numerous NASA resources that can help develop one’s skills further.

Directed toward agricultural and water resource managers, decision makers, and anyone interested in using NASA data to monitor crop production and water availability, this pathfinder directs users to NASA’s land-based data, surface and groundwater data, and vegetation health data.
For ecologists, conservation managers, decision makers, and others interested in using NASA data to monitor biodiversity and forecast changes to ecological communities, this pathfinder provides access to NASA’s vegetation health, spectroscopy, and species distribution modeling data, as well as data for monitoring human-induced changes.
For emergency managers, decision makers, and anyone interested in using NASA data to understand the vulnerability and exposure of a community to a disaster, this pathfinder series (cyclones, floods, and more) directs users to NASA datasets that can aid in monitoring contributing factors, measuring and mitigating risk, and assessing post-event impacts.
While sensors aboard Earth observing satellites cannot detect the spread of diseases from space, they provide long-term data records that help address, inform, and monitor many environmental variables that contribute to habitat suitability for vectors, seasonality, and transmission. This pathfinder provides links to relevant datasets and examples of tools that can be helpful in working with these data.
A Geographic Information System (GIS) is a computer system that analyzes and displays geographically referenced information from a variety of data sources to map and examine changes on Earth. This Data Pathfinder provides a general overview of GIS with links to specific NASA resources, including using NASA data in a GIS.
This pathfinder provides access to commonly-used data on greenhouse gases and is geared toward researchers in need of satellite, airborne, or ground-based data on climate-warming gases. The pathfinder highlights data on carbon dioxide, methane, nitrous oxide, ozone, chlorofluorocarbons, and water vapor.
Geared to air quality managers and public/environmental health managers, as well as citizens interested in using NASA data to monitor air quality and correlate it to health conditions, the NASA data available via this pathfinder provides a means to visualize trends, aid in forecasting events or the movement of pollutants, and respond to events.
For city planners, decision makers, and others interested in using data to monitor changes and assess impacts, and risks associated with changing sea level. This pathfinder directs users to NASA datasets that can aid in tracking changes in glaciers and ice sheets, ocean processes, land water storage, and other factors contributing to a changing sea level.
This series of pathfinders provide NASA observations or high-level products that are useful to produce SDG indicators, support SDG monitoring and implementation, and evaluate progress toward achieving sustainable development. The data have been grouped by SDG. These will be released as they are completed.
This pathfinder is geared to water quality managers and researchers who have a critical need to monitor bodies of water locally, regionally, and globally. It also helps those who are trying to determine the impacts of changes in water quality to ecosystems, humans, and the environment and to restore and protect coastal and surface waters.
