glacierhack2017

Code and notes for the 2017 UW eScience geohackweek GlacierHack project.

See the wiki for results

Objectives

To learn new skills to work with large raster datasets, specifically high-resolution DEMs
Learn how to calcluate elevation change, volume change, and geodetic mass balance from DEM time series
Learn how to generate glacier surface flow velocity maps from feature tracking of images and DEMs
Explore options to integrate DEM time series and implement various processing steps into Google Earth Engine

Sub-projects (see wiki for more info)

Geodetic mass balance

Lead(s): @spectorp, @mattols

Feature-tracking and velocity map time series

Lead(s): @willkochtitzky @prajjwalpanday

Debris thickness and insolation modeling

Lead(s): @drounce, @tarynblack, @mattols

Lagrangian elevation change for mountain glaciers

Lead(s): @dshean

Candidate sites

Let's identify one or more sites with a good, dense time series of DEM/image data. See count maps and indices.

High-mountain Asia

Packages

Notes on ASP Install

Download the latest ASP binaries for your operating system (Linux or OS X). For bleeding edge, see the daily builds.
Extract: tar -xzvf StereoPipeline--x86_64-.tar.gz (filling in the appropriate filename)
Move the extracted folder to a location on your system where you store executables (e.g., bindir="~/sw" or bindir="/usr/local/bin"): mv StereoPipeline--x86_64-/ $bindir
Add the ASP bin subdirectory to your path. In bash: export PATH=${PATH}:$bindir/StereoPipeline--x86_64-/bin. To make this permanent, add that line to your ~/.bashrc or ~/.bash_profile.
