ASF DAAC Data Access and Tools

Data at the Alaska Satellite Facility can be accessed through Earthdata Search. ASF also offers both browser and programmatic services for accessing and downloading data. 

Access to ASF data requires an Earthdata Login account, and the ASF End User License Agreement (EULA) must be completed when logging in to Vertex for the first time.

ASF Data Discovery Services

VertexA powerful yet easy-to-use graphical interface for creating searches, refining results, and downloading SAR data from the ASF archive.
asf_searchSearch and download SAR data with just a few lines of Python. Available via PyPi and Conda, this module is ideal for Python users developing new tools.
Search APIA REST API that provides access to the ASF data archive. It supports Wget, cURL, and most programming languages.

ASF Data Processing Services

HyP3A free, on-demand cloud processing service that offers analysis-ready RTC and InSAR products from Sentinel-1 SAR data. The HyP3 service is integrated into Vertex for a seamless data discovery and processing experience. HyP3 is also available through a REST API and  Python SDK.
HyP3+This option lets you purchase processing credits as needed, avoiding the credit limit and shared processing queue of the basic HyP3 service. HyP3+ is built into the Vertex+ interface, offering a seamless search and processing experience, and is also available through an API and Python SDK.
