pyDendron

Dendrochronology: Wikipedia

``Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the exact year they were formed in a tree. As well as dating them, this can give data for dendroclimatology, the study of climate and atmospheric conditions during different periods in history from the wood of old trees. Dendrochronology derives from the Ancient Greek dendron (δένδρον), meaning "tree", khronos (χρόνος), meaning "time", and -logia (-λογία), "the study of".''

pyDendron

pyDendron is an open-source python package dedicated to dendrochronology. It provides a web GUI to manage, trace, interdate data. pyDendron is developed by members of the GROUping Research On Tree-rings Database ([GROOT] (https://bioarcheodat.hypotheses.org/6241)), one of the three workshops of the [BioArcheoDat] (https:// bioarcheodat. hypotheses.org/) CNRS interdisciplinary research network.

Development is in its early stages. Bugs are provided free of charge like the source code.
