NISAR Data Access and Tools

Download NISAR datasets and access tools to help you find, analyze, and visualize the data.  

Tools like Vertex, the ASF API, asf_search, and Earthdata Search help users search for data, download it, and use it in their own projects. These tools support different workflows, from simple web searches to advanced, automated access.

NISAR data are stored in an AWS cloud bucket, which allows users to work directly with the data without downloading large files. For advanced users, direct S3 access makes it possible to process data in the cloud, saving time and computing resources.

See below the datasets table for a list of tools for working with NISAR data.
