Natural Capital Ecosystem Assessment: NE1.6 Change Detection - Scoping object-based change detection for Living England.
Abstract
The purpose of this review is to highlight key issues in existing object-based change detection (OBCD) and identify potential solutions and recommendations for performing OBCD to the Living England team. The review concludes by providing a set of recommendations including to maintain the spatial framework from one of the input maps to analyse imagery from both time points to avoid production of sliver polygons and to further investigate approaches to detect changes along habitat boundaries when maintaining the spatial framework. In addition, a reduction to the number of transition classes being detected is suggested to reduce the amount of reference data needed to assess the accuracy of the change detection product.
