Urban cartography enables us to trace the historical and spatial evolution of human settlements, but it also furnishes us with the opportunity to obtain and analyse urban data from the perspective of the present day. Urban plans drafted for the reform and expansion of a city can provide us with valuable urban information about the planned use of new public space. In Western Europe, the historical cartography of Barcelona (Spain) maps the city’s mid-nineteenth century urban expansion project designed to fulfil egalitarian, social and hygienist goals. Here, using geographic information system tools, we digitize Barcelona’s cartography so as to create an urban dataset based on the city’s urban plans – the Cerdà Plans (1859 and 1863) – and to estimate its public space typology. Social centres, hospitals, green spaces, residential areas and communication infrastructures are identified and metrised, and urban public open spaces are analysed using various urban indicators. The urban data thus obtained represent a notable advance on attempts to quantify Cerdà’s original project. The importance attached to public space (>75%) and to both communication infrastructure and urban public open spaces is indicative of the desire to create a new city and to break with the values of old Barcelona. In short, the data obtained serve to undertake a detailed comparison with the present-day reality of Barcelona.

城市制图使我们能够追踪人类住区的历史和空间演变，但同时也使我们有机会从当今的角度获取和分析城市数据。为城市的改革和扩张而起草的城市计划可以为我们提供有关计划使用新公共空间的宝贵城市信息。在西欧，巴塞罗那（西班牙）的历史制图绘制了该城市19世纪中叶的城市扩张项目，旨在实现平等，社会和卫生的目标。在这里，我们使用地理信息系统工具对巴塞罗那的制图进行数字化处理，从而根据该城市的城市规划（塞尔达规划（1859年和1863年））创建城市数据集，并估算其公共空间类型。社会中心，医院，绿地，确定并确定居住区和通信基础设施，并使用各种城市指标分析城市公共开放空间。这样获得的城市数据代表着对量化Cerdà原始项目的尝试的显着进步。公共空间（> 75％）以及通信基础设施和城市公共开放空间的重视程度表明了创建新城市并打破旧巴塞罗那价值观的渴望。简而言之，所获得的数据有助于与巴塞罗那的当今现实进行详细的比较。公共空间（> 75％）以及通信基础设施和城市公共开放空间的重视程度表明了创建新城市并打破旧巴塞罗那价值观的渴望。简而言之，所获得的数据有助于与巴塞罗那的当今现实进行详细的比较。公共空间（> 75％）以及通信基础设施和城市公共开放空间的重视程度表明了创建新城市并打破旧巴塞罗那价值观的渴望。简而言之，所获得的数据有助于与巴塞罗那的当今现实进行详细的比较。
