GIV is an open source tool for creating high-resolution glacier velocity maps through feature tracking of optical satellite images. In particular, GIV is aimed at:

- Processing large temporal datasets (for example, all Sentinel-2 images of a particular glacier) into velocity timeseries
- Pre and post-processing imagery to improve velocity map quality, all in one workflow
- Being quick and easy to use (no coding needed, adjust all of the parameters through a user interface)
 
To find out more, we have a recent paper in The Cryosphere (http://doi.org/10.5194/tc-15-2115-2021) that discusses some examples. Links to download the source code and user interface, along with a user manual and video tutorial are available on my website.
 
In the first video of the tutorial, I go through how you generate your own velocity maps of any glacier in 10 minutes (https://youtu.be/mu15GX2jy20). For instance, you can use this to support fieldwork (track your ablation stakes!), quickly cross-validate any other technique, or to support teaching and undergraduate projects.
 
Cheers – and let me know if you have any questions about GIV,
