Exploring what's between ICESat-2 reference tracks
ICESat-2 has done an amazing job measuring elevations on its reference tracks, but what if you're interested in someplace that isn't covered? In this project, we'll use the tools developed to create the ICESat-2 gridded products to generate a custom gridded elevation-change product for your favorite location. We'll work on developing techniques to use data from the SlideRule online processing service to make elevation and elevation-change maps, and will work on tuning parameters in the algorithm to match conditions for the locations we're mapping.

ICESat-2 makes great measurements on its repeat tracks, but data can be sparse in between. In this project, we're going to work on gridding techniques to fill in the gaps between ICESat-2 tracks. We have participants interested in:
- Divide-scale elevation change in Greenland
- Ice-front-scale elevation change in Helheim glacier
- Permafrost change in Alaska
We'll try to find the best collection of techniques for each.
We'll get data from SlideRule, with the option to get additional DEM data from the Polar Geospatial Center's REMA and ArcticDEM arcives.
One of the goals of this project is to make the tools that generate ATL14/15 more that are more useful to the community. This includes the code in the main ATL14/15 repository, and the code in the more general-purpose LSsurf repository

- Document grid-fitting algorithms
- Adapt grid-fitting scripts to SlideRule processing output
- Tune grid-fitting parameters to selected field locations
