Visualizing Multidimensional Climate Data on the Web with Zarr and @carbonplan/maps Kata Martin & Shane Loeffler, CarbonPlan Climate data (and many other scientific datasets) are often massive, multidimensional, and challenging to get into desktop GIS and cartography tools, let alone a web map. @carbonplan/maps is an open-source tool for efficiently visualizing this complex data on the web by leveraging the emerging Zarr format and WebGL. Here we showcase its use in a recent project exploring a new dataset simulating the efficiency of ocean alkalinity enhancement (OAE), a carbon removal technique. The OAE Efficiency Map allows exploration of nearly 700 global ocean simulations, allowing scientists and system actors to get a better sense of where and when the most effective carbon removal is possible.
Felt in Action Mamata Akella, Felt Felt is a powerful tool for data exploration, spatial analysis, cartography, and collaboration. It enables more people in your organization to work with maps and collaborate in real time through its modern, easy-to-use interface packed with powerful features. Join this talk to learn how to work with a variety of data formats, advanced filtering and search capabilities, robust spatial analysis tools, and intuitive cartographic controls that together, simplify the data exploration and mapmaking process and are uniquely Felt. Whether you are a beginner or an experienced professional, see how Felt improves workflows, enhances team communication, and enables informed decision-making through practical examples and a live demo.
Integrating Use-Specific Styles into a Generalized Map Hierarchy Lauren James, Apple Apple’s Maps app is constantly evolving as we create new offerings for our users. Our latest undertaking necessitated integrating new data into an existing hierarchical structure, with emphasis on a considered and balanced redesign of layers. This challenging puzzle included needed technical advancements across several codebases and a cross-functional effort. Maps’ Cartography team will present the design and data decisions behind this undertaking.
Visualizing Change: How Map Design Shapes Our Views on Glacier Retreat Fangsheng (Jasper) Zhou, University of Oregon This presentation explores the emotional and perceptual impacts of 2D versus 3D map designs on viewers' understanding of glacier retreat due to climate change. Utilizing the South Cascade Glacier as a case study, this research examines how different visual representations can influence public perceptions and emotional responses to environmental changes. Through a user study involving a diverse group of participants, the study aims to highlight the effectiveness of map design in communicating complex geographic information and raising awareness about the pressing issue of climate change.
Introducing Tiled Texture Shading Leland Brown, Instituto Superior Técnico (IST), Lisbon, Portugal Texture shading is an algorithm to enhance visual detail in canyons, ridges, and structural features of a terrain. But suppose you want a seamless map of a very large area. If you divide the map into tiles and texture shade each one separately, the tiles won't match properly at the edges. Until now, the only solution was to process the entire dataset as a unit, potentially needing more time or memory space than you have available. Now the algorithm has been extended to process tiles individually while taking into account their context in the surrounding map. The result is texture-shaded tiles that fit together seamlessly into a single image. This makes texture shading practical even on datasets of 100,000 x 100,000 pixels or larger.
My interest in cartography stems from my love of hiking and of mathematics. I'm especially interested in mountain terrain representation and raster images.
