Description

LakeDetect is a Python library for mapping open water from satellite imagery. It computes the Normalized Difference Water Index (NDWI) from the green and near-infrared bands, turns it into a water mask with a configurable threshold, optionally cleans the mask with morphological filters, and calculates the resulting water-surface area. Helper functions for reading imagery, writing georeferenced results and plotting are included.
