Open source tools

autoRIFT: A highly accurate and efficient algorithm for finding the pixel displacement between two radar or optical images

NSIDC notebook: A Jupyter notebook to search and download ITS_LIVE scene-pair velocity.

Chad Greene's Matlab collection: A set of Matlab functions for accessing, analyzing, and plotting ITS_LIVE velocity data. These functions are intended to streamline the process of loading ITS_LIVE mosaics, interpolating, generating flowlines, and creating maps of ice flow.

ITS_LIVE API: An API for searching ITS_LIVE scene-pair velocities.

Geogrid: A Python module for precise mapping between (pixel index, pixel displacement) in imaging coordinates and (geolocation, motion velocity) in geographic Cartesian (northing/easting) coordinates

Emma Marshall's ITS_LIVE tutorial: A Jupyterbook tutorial to demonstrate how to access and work with with multi-dimensional remote sensing data from ITS_LIVE using xarray.

Jacob Fahnestock's velocity webapp: A serverless React-Leaflet website to plot and share ITS_LIVE data
