PolSAR Data Documents
UAVSAR produces one kind of Polarimetric synthetic aperture (PolSAR) data for each acquisition.
InSAR Data Documents
UAVSAR produces three kinds of repeat pass interferometric synthetic aperture (InSAR) data described below.
InSAR Browse Products
Repeat pass InSAR browse products are low-resolution products intended to give users an idea of the quality of data collected for repeat pass interferometry and a rough indication of whether an interferogram contains useful signals. They contain kml, kmz and metadata files, as well as data quality metrics such as absolute and relative motion information. They are automatically generated for sequential pairs.

InSAR Pair Products
Repeat pass InSAR pair products are high-resolution interferometric products for in-depth scientific analysis. They contain slant range and ground range interferogram, unwrapped phase, coherence, amplitude, as well as ground range digital elevation map (DEM) and metadata files. InSAR pair data are processed based on PI request using the UAVSAR web tool. They can have residual motion corrected or uncorrected based on PI choice.

SLC Stack Products
Repeat pass SLC stack products are co-registered time series data. They contain slant range single look complex (SLC), latitude/longitude/height, look vector, doppler, and metadata files. SLC stack data are processed based on PI request using the UAVSAR web tool. They can have residual motion corrected or uncorrected based on PI choice.
InSAR Stack SLC Data Format
Currently, InSAR pair and SLC stack processing requests are limited to principal investigators (PIs). Here are instructions for PIs to review and select those products for release.
