The repository stores code, land-use dataset, and reverse-viewshed maps to calculate capacity potential for Offshore Wind, Onshore Wind, and Open-field PV in Japan for the base scenario and under visibility restriction from important landscapes. The code use ETHOS.GLAES (https://github.com/FZJ-IEK3-VSA/glaes) for land eligibility analysis and capacity potential calculation under the open-source workflow ETHOS.REFLOW (https://github.com/FZJ-IEK3-VSA/ethos.REFLOW).
