Worldview, developed by NASA, is an interactive open source online tool that allows users to explore the Earth's surface as it appears in near real-time, as well as through historical satellite imagery. It provides access to satellite data and imagery collected from various NASA Earth observing missions, offering users the ability to view and analyze environmental events, changes, and phenomena on a global scale. The tool is designed to cater to both scientific and educational purposes, making it a valuable resource for researchers who are interested in observing Earth's dynamic systems. Users can customize their view by selecting different layers such as air quality, temperature, precipitation, and more, making it a versatile platform for environmental monitoring and analysis.
Worldview has many pre-made animated Stories for inspiration. These include:

NASA Worldview has several limitations users should be aware of:
Learning Curve: New users may find the interface and array of datasets overwhelming, requiring time to learn how to effectively navigate and utilize the tool.
Analysis Capabilities: While Worldview allows for visualization, it does not offer extensive built-in tools for data analysis. Users might need to use other software for detailed analysis.
Data for download: Data will not be available on dates outside of each layer's respective coverage date range. In addition, some layers in Worldview do not have corresponding source data products available for download, including Geostationary, Reference, Orbit Tracks, Earth at Night, and MODIS Corrected Reflectance products.

Platform updates and changes
Data Availability: Not all satellite data are available in near real-time or with a high temporal resolution. Some datasets may have a lag of several days or are updated less frequently. There are a number of imagery products available in Near Real Time. Both MODIS (Moderate Resolution Imaging Spectroradiometer) and VIIRS (Visible Infrared Imaging Radiometer Suite) have data sets that are available daily like the VIIRS . Use the Base Layers menu to filter for Period: Daily to find more datasets.
Resolution: The spatial resolution of images and data can vary significantly between datasets. Some regions or types of data might not be available at the desired resolution for detailed analysis. The highest resolution imagery is 10 meters per pixel for RGB and near-infrared bands, 20 meters per pixel for shortwave infrared bands and can be added as a base layer from the Base Layers menu.
