Python Search Module

The Python Search Module (asf_search) greatly simplifies the search and download processes, allowing users to find and download SAR data in just a few lines of Python. Available through PyPi and Conda, this module is targeted at Python users writing new tools, and users looking for an easier alternative to ASF’s SearchAPI.

Direct S3 Access

Scientists, researchers and students working in the cloud can utilize direct S3 access to work with NISAR data without having to download it. Through these capabilities a user requests temporary AWS credentials that leverage the many existing tools for working with S3 data including Boto3 and GDAL.

Image Services

Users can explore a global mosaic of analysis-ready data through time in a browser-based web map or directly in their GIS software platform. Access and analyze NISAR data without having to download the data first. Check out the image service functionality with this interactive map displaying services generated from ASF’s On- Demand RTC products.

Work in the Cloud

Services such as ASF’s OpenScienceLab (OSL) provide researchers, scientists, and developers access to a powerful set of open-source tools and resources for satellite data processing and analysis through a JupyterLab environment. OSL is designed to simplify the use of SAR data.

The NASA ASF DAAC will serve as the primary hub for archiving and distributing NISAR’s L-band SAR data.
Planned Launch Date: 2024.
