Abstract
Abstract. This paper reports on Intertidal – a collaborative project to demonstrate integrated workflows to 3D spatial data infrastructure (SDI), simulations and geovisual interfaces - as integrated approaches to support the 3D characterization of coastal morphology, intertidal dynamics, potential sea level rise, and mitigation responses to them. Specifically, this project emphasized the potential of emerging 3D data, new analytical visualization methods, and emerging 3D interface technologies as ingredients of emerging and future environmental data science and visualization practice of coastal/intertidal environments.

Environmental change driven by climate change has the potential to manifest in multiple ways
In addition to producing new high resolution datasets, this project produced a set of 3D interface prototypes, each of which helped us explore the potential of datadriven 3D spatial interfaces, as new mediums through which to transform the way we connect with intertidal phenomena through data, and fundamentally new ways to conduct spatial information science
These prototypes included: 3D fluid simulations in and across intertidal spaces, revealing exactly how beach armoring practices modify ocean velocity (Figure 3); immersive virtual reality (VR) environments allowing users walk around a ~1cm-resolution virtual reconstruction of a marine park and interactively manipulate the ocean, to understand future sea levels and their intersection with high fidelity intertidal spaces (Figure 4); and a tabletop augmented reality (AR) sea level visualization tool intertidal zone at different future sea levels (Figure 5)
Summary
Environmental change driven by climate change has the potential to manifest in multiple ways. While geographical information systems have evolved considerably over the past decades, their primary purpose, as working spatial analytical tools, means that they are often too abstract for comfortable use by policymakers in engagements with society and citizens This is perhaps why the more recent groundswell of 3D environmental visualization work has adopted and integrated novel 3D visualization platforms, such as 3D game engines, as the foundation for spatially rigorous, but visually compelling, and engaging climate change visualization systems. Less overwhelming abstract information, enhanced geographical realism (resulting from rendering engines derived in AAA game technology), sophisticated 3D topological representation, 3D physics engines, artificial intelligence algorithms, and streamlined interactivity – have attracted geographic visualization experts as an incredibly rich environment with which to create distinctive and spatially rigorous visualizations f environmental change This watershed has not gone unnoticed by the commercial GIS community, and has resulted in increasing interplay between the spatial analytical industry (such as Bentley, ESRI, QGIS, the game-building community (such as Unity, Unreal), and a wide range of developers and users. Derived from them, are contributing to a groundswell of effort to produce completely 3D geographical information systems, analyses, visualizations and visualization interfaces
