Yet Another Time Series Model (YATSM): v0.4.0

Authors/Creators

  • 1. Boston University

Description

The Yet Another TimeSeries Model (YATSM) algorithm is designed to monitor land
surface phenomena, including land cover and land use change, using timeseries
of remote sensing observations. The algorithm seeks to find distinct time
periods, or time segments, within the timeseries by monitoring for disturbances. These time segments may be used to infer continuous periods of stable land cover, with breaks separating the segments representing ephemeral disturbances or permanent conversions in land cover or land use.

"The Yet Another..." part of the algorithm name is an acknowledgement of the influence a previously published timeseries algorithm - the Continuous Change Detection and Classification (CCDC) (Zhu and Woodcock, 2014) algorithm. While YATSM began as an extension from CCDC, it was never intended as a 1 to 1 port of CCDC and will continue to diverge in its own direction.

Notes

Model specification improvement and dataset caching improvements. Tasks include: - Updating cache files with new data - "cache_yatsm.py" cache dataset updater - Model design matrix specification using Patsy syntax - QA/QC for yatsm_map.py Move to Patsy style model specification (see #25) makes previous results incompatible with release.
