ASF User Services
Fine Beam Dual-Pol ascending coverage of the blue regions is the plan from the basic observation strategy for Cycle 20 this summer
ASF User Tools

Freely available software (BSD license).
Developed with an intention to increase the usability of SAR data.
Intuitive user interface enables those with little or no SAR experience to readily process it for use with other data layers.
Ingests ASF, CEOS, and GeoTIFF data formats.
Can export the data to JPEG, GeoTIFF, PNG, and some other formats.
Geocodes data to any of five popular map projections
UTM, Polar Stereographic, Lambert Azimuthal Equal Area, Lambert Conformal Conic, Albers Equal Area
Terrain corrects (orthorectifies) to remove artifacts commonly seen in SAR data such as layover and shadow.
Includes support for multiband data such as polarimetric data.
Batch processing ability allows users to process large volumes of data at once.
Preview images are visible for each item in the batch list (input and output).
Includes a metadata viewing tool.
Input and output images can be viewed in full resolution with the integrated ASF View tool.
Image footprint can be viewed in Google Earth™.
Goals for the near future:
Support for Single Look Complex data.
Improved support for polarimetric data.
Ability to ingest and process AirSAR data.
Ability to ingest and process data written by the Gamma software.
This simple tool allows users to create a shape or kml file based on images that may not be viewable but have metadata.
The area’s footprint can then be viewed using Google Earth™ or ArcMap™.
Non-lat/lon metadata is passed along as attributes.
Windows release planned for May 1st.
Pending testing & validation.
