Development of Qgis Plugin to Monitor the Health Condition of a Lake

Abstract

Monitoring the quality of surface water is an important step towards sustainability of water resources. Quantum Geographic Information System (QGIS) is an opensource desktop application which is used for editing and analysing geospatial data. This study aims to develop a QGIS plugin named Lake Ecosystem Tool to monitor the health condition of a lake in terms of water quality index, trophic state index, hazard quotient, aerial water spread and volumetric change and the same can be used as a planning tool for the sustainable management of existing water bodies.
