PhenoVis – A tool for visual phenological analysis of digital camera images using chronological percentage maps

Phenology studies the periodic phenomena of plants and their relationship to environmental conditions, which is crucial for accessing the impact on vegetation and ecosystem processes. In this paper entitled “PhenoVis – A tool for visual phenological analysis of digital camera images using chronological percentage maps“, the authors introduce PhenoVis, a visual analytics tool that aims at providing insightful ways to analyze phenological data. The main idea behind PhenoVis is the creation of more expressive visual encodings for phenological data visualization. It contains the chronological percentage maps (CPM), a novel representation that is capable of discovering additional patterns by encoding percentage distributions of the data.

Selected screenshots of the PhenoVis interface: (A) CPM analysis mode, with interaction to inspect individual images and specify query windows; (B) multi-rank results with pairwise comparison of all years; (C) single-rank results using fixed and moving windows. In (D), we display additional windows for configuring search parameters
