Issues faced when developing an atlas for both paper and online

Two years ago we started an atlas project: The atlas of the world of ITC -the impact of capacity development It narrates the activities of ITC, the Faculty of Geo-Information Sciences and Earth Observation of the University of Twente, the Netherlands.It resulted in a hybrid atlas, an atlas published on multiple mediums: digitally as an online edition and analog as a printed edition.This is not necessarily new.Often an online interactive version is derived or based on a printed atlas or the other way around.The hybrid atlas production considers both a digital and analog edition from the beginning.Both editions are considered not complementary but combined.Earlier we (Kraak et al, 2023) noted that two major challenges originate from the atlas' hybrid nature: the visual coherence between both editions, and an efficient single-source-publishing workflow.The objective of this contribution is to elaborate on the challenges faced in this process.
