The Alaska Satellite Facility (ASF) has developed and deployed an Application Programming Interface (API) as an additional avenue to access the SAR Data Center’s (SDC) archive. The purpose of this API is to present users a flexible Web service that facilitates the search for and visualization of ASF datapool assets, as well as delivery of relevant metadata about those assets. The API facilitates the bulk delivery of ASF holdings to the SAR data user community in an efficient and accurate manner.
The API can be used in numerous ways to process queries as HTTP GET or HTTP POST data requests. Requests need to contain only one of the three required parameters to succeed: bbox, path, or granule list. Returns from the API are in either csv, kml, or Metalink file formats and are not limited to 1,000 granules, allowing for direct access to granules in the ASF datapool.
Additional detailed information about the API and how to use it in your research can be found at, http://www.asf.alaska.edu/program/sdc/asf_api. Development of additional parameters to refine queries to and returns from the ASF API is ongoing in response to user needs. Please contact ASF if there is a specific parameter that would be useful in your search and visualization of the SDC holdings.
