HedgeTools : un outil d’analyse spatiale dédié à l’évaluation de la multifonctionnalité des haies

Abstract

Hedgerows plays key roles in agricultural landscapes but their automatic characterization by spatial analysis is complex. In this article, we describe the main functionalities of an open source tool – HedgeTools – which makes it possible to calculate a variety of indicators helping to assess the multifunctionality of hedges. It allows for creating the geometry of objects, cutting them according to various criterias, and extracting their characteristics at different levels of aggregation. HedgeTools aims to facilitate the management and preservation of hedges by making it possible to evaluate their condition and their functions in landscapes, with prospects for improving and extending its functionalities.
