What Maps Tell Us: Introduction to Cartographic Thinking
第一章:地图告诉我们什么:制图思维的入门
地图:人类理解世界的方式
Every time we unfold a map, spread a napkin to sketch a meeting point, or tap our phone to see our location on a digital display, we participate in one of humanity's oldest and most universal activities. Mapmaking—cartography, to use the formal term—has been with us for thousands of years, appearing independently in every culture humans have ever inhabited. It is not merely a technical skill or a professional practice confined to navigators and geographers; it is, I will argue throughout this book, a fundamental way that our species makes sense of the world.
每当我们展开一幅地图、在餐巾纸上勾勒一个会面地点,或者点击手机查看自己在数字屏幕上的位置时,我们都在参与人类最古老、最普遍的活动之一。制图——使用更正式的术语来说是cartography(地图学)——已经伴随我们数千年,独立出现在人类曾经居住过的每一种文化中。它不仅仅是一门技术技能或仅限于航海家和地理学家的专业实践;我认为,正如本书将要论证的那样,它是人类这个物种理解世界的一种基本方式。
Consider what happens when you look at a map. Your eyes travel across a flat surface, yet your mind constructs a three-dimensional world. You recognize symbols—blue lines for rivers, brown curves for elevation, dots for cities—and instantly translate them into landscape features you may have never seen. You orient yourself, finding "here" and "there," and begin to imagine the paths and distances between them. In this simple act, something remarkable occurs: the vast, complex, continuous reality of the world gets translated into a bounded, simplified, symbolic representation that your brain can comprehend, manipulate, and share with others.
想想看,当你注视一幅地图时会发生什么。你的目光在一张平面上游走,而你的大脑却构建出一个三维世界。你识别出符号——蓝色线条代表河流,棕色曲线代表海拔,圆点代表城市——并立即将它们转化为你可能从未见过的景观特征。你定位自己,找到“这里”和“那里”,然后开始想象它们之间的路径和距离。在这个简单的动作中,某种非凡的事情发生了:世界那广阔、复杂、连续的真实面貌,被转化为你大脑能够理解、操作和与他人分享的有界限的、简化的、符号化的表达。
This translation from reality to representation is what cartography is all about. And it is far more than a neutral technical exercise. Every map is a Choices about what to include and what to omit, what to emphasize and what to subordinate, what projection to use and what symbols to deploy. These choices reveal what its maker considered important, what questions they wanted to answer, and what worldview they inhabited. Maps, in other words, are never simply copies of the world—they are arguments about it.
这种从现实到表征的转化正是制图的核心所在。而且这远非中性的技术活动。每一幅地图都是一系列选择的结果——选择包含什么、忽略什么,强调什么、弱化什么,使用什么投影和什么符号。这些选择揭示了制作者认为重要的东西,他们想要回答的问题,以及他们所处的人文环境。换言之,地图从来不是世界的简单复制品——它们是关于世界的论证。
This insight—that maps are arguments—will be one of the central themes of this book. But before we can understand maps as arguments, we must first understand them as representations. We need to grasp the fundamental concepts that underlie all mapmaking: scale, projection, and symbolization. We need to see how these concepts manifest in actual maps from different times and places. And we need to develop what I will call "cartographic thinking"—a set of habits and skills for reading maps critically and creatively. That is the task of this opening chapter.
这一洞见——地图是论证——将成为本书的核心主题之一。但在我们能够理解地图作为论证之前,我们必须首先理解它们作为表征的本质。我们需要掌握制图学的基本概念:比例尺、投影和符号化。我们需要看到这些概念如何在不同时代和地区的实际地图中呈现。我们还需要培养我所说的“制图思维”——一套用于批判性和创造性阅读地图的习惯和技能。这就是本章的任务。
地图的普遍性:人类共同的语言
One of the most striking facts about cartography is its universality. From the Inuit of the Arctic to the Aboriginal Australians, from ancient Babylon to modern Japan, every human society we know of has created maps. This is not merely a historical curiosity; it suggests something profound about human cognition. When a practice appears independently across such diverse cultures, separated by vast distances and millennia of time, we can reasonably suspect that it taps into something basic about how our minds work.
关于制图学最引人注目的事实之一是它的普遍性。从北极的因纽特人到澳大利亚的原住民,从古巴比伦到现代日本,我们所知的每个人类社会都曾创造地图。这不仅仅是一个历史奇闻;它暗示了关于人类认知的深刻含义。当一种实践在如此多元的文化中独立出现,被巨大的距离和数千年的时间分隔开来时,我们可以合理地推测,它触及了我们思维运作方式的某些基本层面。
The evidence for this universality is remarkable. The Mbuti people of the Congo rainforest in Central Africa navigate their forest home using mental maps so precise that outsiders find them almost incomprehensible. When asked to draw their territory on paper, they create maps that prioritize relationships—paths, connections, places of significance—over literal geographic accuracy. The Polynesian navigators of the Pacific Ocean, who settled islands thousands of miles apart across the open sea, developed entirely different mapping traditions. Rather than drawing pictures, they used physical devices: sticks and shells arranged to represent islands, ocean swells, and wind patterns. These "stick charts" encoded vast amounts of navigational knowledge in a portable form.
这种普遍性的证据令人瞩目。中非刚果雨林中的姆布蒂人使用心理地图在其森林家园中导航,这些地图精确到让外人几乎无法理解。当被要求在纸上绘制他们的领地时,他们创造的地图优先考虑关系——路径、连接、有意义的地方——而非字面上的地理准确性。太平洋上的波利尼西亚航海家——在公海上定居于相隔数千英里的岛屿——发展出完全不同的制图传统。他们不是画画,而是使用物理工具:用棍子和贝壳排列来代表岛屿、洋流和风模式。这些“棍棒图”以便携形式编码了大量的导航知识。
Even more revealing are the maps created by children who have never been formally taught cartography. Studies by developmental psychologists have shown that young children, given paper and crayons, spontaneously create territorial maps. They draw their homes, their schools, their favorite places, and the paths between them. These spontaneous maps share key features with the maps of adult cartographers: they simplify complex reality, emphasize what is important to the mapmaker, and use symbols to represent features of the world. This suggests that the impulse to map—to translate space into symbolic representation—is not learned from culture but emerges naturally from the human mind.
更具启示意义的是那些由从未接受过正规制图教育的儿童创造的地图。发展心理学家的研究表明,给予幼儿纸和蜡笔,他们会自发地创造领地地图。他们画出他们的家、学校、最喜欢的地方,以及它们之间的路径。这些自发的地图与成年制图师的地图共享关键特征:它们简化复杂的现实,强调对制图者重要的东西,并使用符号来表示世界的特征。这表明,制图的冲动——将空间转化为符号表征——不是从文化中学来的,而是从人类头脑中自然产生的。
What, then, are we to make of this universal human impulse? The cognitive scientist and geographer Mark H. B. M. has argued that humans possess an innate "spatial cognition" faculty—a set of mental abilities that evolved to help our ancestors navigate complex environments, remember the locations of resources and dangers, and communicate about space with others. Maps, in this view, are externalizations of our internal spatial representations. When we make a map, we take the mental images, spatial relationships, and geographic knowledge that exist in our heads and make them visible and shareable.
那么,我们该如何理解这种普遍的人类冲动?认知科学家兼地理学家马克·H·B·M认为,人类拥有先天的“空间认知”能力——一套心理能力,进化来帮助我们的祖先在复杂环境中导航、记住资源和危险的位置、并与他人交流空间信息。在这种观点中,地图是我们内部空间表征的外化。当我们制作地图时,我们将存在于头脑中的心理图像、空间关系和地理知识变得可见和可分享。
This does not mean that all maps are the same, or that cartography is simply a mirror of nature. Far from it. The specific forms that maps take vary enormously across cultures and through time, reflecting different technologies, different purposes, and different ways of understanding the relationship between humans and the world. But underlying this diversity is a common cognitive infrastructure—the universal human capacity to represent space symbolically. It is this capacity that makes cartography possible, and it is the elaboration of this capacity that makes the history of maps so rich and fascinating.
这并不意味着所有地图都是相同的,或者制图学只是自然的镜像。远非如此。地图所采取的具体形式在文化和时间上差异巨大,反映了不同的技术、不同的目的,以及理解人与世界之间关系的不同方式。但在这个多样性之下是一个共同的认知基础设施——人类用符号表征空间的普遍能力。正是这种能力使制图学成为可能,正是这种能力的精细化发展使得地图的历史如此丰富和迷人。
地图的要素:理解制图的语言
To read maps critically and creatively—to understand what they tell us and what they hide—we must master the basic vocabulary of cartography. Three concepts are fundamental: scale, projection, and symbolization. These are the tools that cartographers use to translate the three-dimensional, curved, infinitely complex world into a two-dimensional, flat, manageable representation. Understanding these concepts is the first step toward cartographic literacy.
要批判性和创造性地阅读地图——理解它们告诉我们什么以及隐藏什么——我们必须掌握制图学的基本词汇。三个概念是根本性的:比例尺、投影和符号化。这些是制图者用来将三维、弯曲、无限复杂的世界转化为二维、平面、可管理的表征的工具。理解这些概念是迈向地图素养的第一步。
Scale: The Art of Reduction
Scale is the ratio between the distance on a map and the corresponding distance on the ground. When we say a map has a scale of 1:50
