Coast Lines: How Mapmakers Frame the World and Chart Environmental Change

Coast Lines examines the history, science, and politics of coastal mapping from the 1800s to the present day. The book tracks how cartographers have attempted to define and document the ever-shifting boundary between land and sea. Monmonier explores key technical and practical challenges in coastal mapping, from early challenges with tide measurement to modern satellite and GPS technologies. The text covers both the evolution of mapping methods and the real-world implications of how coastlines are officially defined and recorded. Through historical examples and case studies, the book demonstrates how coastal maps impact property rights, national boundaries, and environmental policy. The legal and political consequences of various mapping approaches are examined across different contexts and time periods. This work highlights the intersection of scientific methodology with human systems of law and governance, revealing how technical choices in cartography can have far-reaching societal effects. The book raises questions about objectivity and authority in how humans document and define natural features.

Readers say this book succeeds as an academic study of coastal mapping but falls short as an engaging read for general audiences. Positives: - Clear explanations of technical mapping concepts - Strong coverage of climate change impacts on coastlines - Useful illustrations and examples - Good historical context about map development Negatives: - Dense academic writing style - Too much technical detail for casual readers - Repetitive sections - Limited discussion of environmental policy implications One reviewer noted it "reads like a textbook rather than popular science book." Another said it "contains valuable information but requires real dedication to get through." Ratings: Goodreads: 3.0/5 (8 ratings) Amazon: 3.5/5 (4 ratings) LibraryThing: 3.0/5 (3 ratings) The low number of online reviews suggests this book reached a niche academic audience rather than general readers interested in maps or environmental topics.

🌊 Prior to the standardization of coastal mapping in the mid-1800s, mariners often relied on local knowledge and hand-drawn charts, leading to numerous shipwrecks and navigation disasters. 🗺️ Mark Monmonier has authored twenty books on cartography and mapping, and is a Distinguished Professor Emeritus of Geography at Syracuse University's Maxwell School. 📐 The seemingly simple task of drawing a coastline is actually incredibly complex, as the measured length changes dramatically depending on the scale used - a phenomenon known as the "coastline paradox." 🌎 The book reveals how modern satellite mapping has shown that global coastlines are far more dynamic than previously thought, with some changing significantly within a single human lifetime due to erosion and sea-level rise. ⚓ The first systematic coastal mapping project in the United States began in 1807 with the establishment of the Survey of the Coast (later becoming the U.S. Coast and Geodetic Survey, and now part of NOAA).
