Integração entre Python e QGIS: cálculo de sinuosidade

Abstract

Efficient water resource management, essential for human survival and ecosystem maintenance, is one of the United Nations' goals, with targets for international cooperation and capacity building by 2030. In the technological context, the use Qgis® can assist in analyzing river sinuosity coefficient, a variable that affects erosion, sedimentation, and water quality. However, the lack of specific tools for this analysis in GIS presents a challenge. Thus, creating a specific plugin to calculate river sinuosity coefficient in Python for the Qgis® platform aims to fill this gap, facilitating the monitoring and sustainable management of water resources. A plugin was developed on the PyCharm® platform using Python, with the code divided into eight steps, starting from a directory configured for metadata files and initialization and main logic files, with the support of libraries. The file responsible for calculating sinuosity coefficient equation, and icons can be added. The plugin was installed in Qgis® and activated in the software's complement. The plugin allows the user to select a hydrological segment for the sinuosity coefficient calculation through a vector layer in Qgis®.
