CARST 2.2.0

CARST 2.2.0 updated the dh/dt module with the following major changes:

• Added more fitting methods other than the linear model.
• removed some of SingleRaster's methods since Rasterio provides better ways.
• Renaming methods to fit PEP8 [ongoing]
• Updated dh/dt visualization.
• We use this version to generate our EGU 2024 abstract: Significant subglacial and proglacial lake drainages in the Canadian Arctic identified by time-stamped ArcticDEM strips.

CARST 2.1.0

CARST 2.1.0 updated the dh/dt module with the following major changes:

• added DBSCAN as one way to do the outlier detection.
• added more methods for dh/dt, including parallel options, COG compatibility, and mosaic.
• removed some of SingleRaster's methods since Rasterio provides better ways.
• converting all tab indents to space. [ongoing]
• renaming methods to fit PEP8 [ongoing]
• updated visualization.

We use this version to generate preliminary results for the GlaMBIE project and the AGU 2023 abstract: ArcticDEM-derived elevation change of all Arctic glaciers during 2012–2021 in high spatial resolution.

CARST v2.0.0a1

Cryosphere And Remote Sensing Toolkit (CARST) v2.0 alpha is now available. Here are some major changes since v1.1:

• You can use pip to install CARST now: pip install carst
• The pixeltrack.py script has been renamed to featuretrack.py
• CARST now can be imported in Python as a whole: import carst or from carst import *

This package analyzes satellite images, particularly SAR and optical images, and monitors glaciers and ice caps changes through time. CARST toolkit provides two major workflows as scripts: elevation changes (dhdt.py) and feature tracking (featuretrack.py), as well as various Python modules. Please see the README file and the doc folder for more information.

CARST v1.1.0

CARST v1.1.0: minor bug fixes + some new functions to the dh/dt workflow.

CARST v1.0.1

Cryosphere And Remote Sensing Toolkit (CARST) v1.0.1 has been released. Few small bugs have been fixed from v1.0. Take a look at README for more information!

CARST v1.0

Cryosphere And Remote Sensing Toolkit (CARST) v1.0 has been released. It consists of two major and wide-used workflows: dh/dt (surface elevation change rate) and pixel tracking (surface feature horizontal moving rate), as well as many modules that work the best with geospatial (rasters, texts, vectors) data. Take a look at README for more information!

CARST v1.0-alpha (dhdt v1.0 + pixeltrack v0.2)

dhdt v1.0 is now released with some enhanced performance, such as the EVMD that reviews unreliable elevations.
pixeltrack v0.2 is now under a major rehaul - we will use the ampcor in ISCE (instead of that in ROI_PAC) pretty soon, which makes the whole tool executable using only python.
