### Overview
Tundra Capillary Networks (TCNs) are emerging drainage systems formed through the coalescence and degradation of ice-wedge polygon troughs and represent a key mechanism of hydrological reorganization in permafrost landscapes. This dataset consists of computer vision–derived semantic segmentation outputs and associated graph-theoretic analyses represented in vectorized formats. The data capture the spatial structure, connectivity, and topology of TCNs across heterogeneous Arctic tundra environments.

The purpose of this dataset is to support analyses of Arctic hydrology, permafrost landscape evolution, and geomorphological processes. By providing a standardized, scalable representation of TCN structure and dynamics, this dataset enables comparative studies across space and time and facilitates integration with network-based, statistical, and geospatial modeling frameworks.
