Barcelona in data, between 1867 and 2017. General Theory of urbanization, 1867
Councilor of Barcelona in 1854. The following year, in 1855, he was commissioned by the Ministry of Public Works to lift the topographic map of Barcelona, and this process would lead him to carry out the Ensanche project in 1859.
The theoretical body that accompanied the project would be published as "General theory of urbanization", when it was published in 1867. Being considered later as one of the first treaties on urbanism and the first scientific study in which the word "urbanism" appears "

Cerdá was politically engaged, he became a deputy for Barcelona in the Cortes, forming part of a progressive candidacy along with Estanislao Figueras, Pascual Madoz and Jacinto Félix Doménech.

He was aware of the problems of unhealthiness that had led to the epidemics of 1821 and 1834 (later were also those of 1854 and 1865), and he had proposed to move into practice the hygienist theories in the creation of new cities. He aware that those statistics, collected 150 years ago, were essential in the design of cities and they had a direct impact on the living conditions and mortality of their inhabitants.

Now 150 years later, from the IAAC (Institute of Advanced Architecture of Catalonia) supported by the platform have moved and updated those data to a digital version (comparing the data and situations of 1867 and 2017) presenting itself in open format all the data.

The work is accompanied by the realization of the English version of Cerdà's book, published by the Actar publishing house.

The data of then and the current ones acquire a new value when superimposing themselves three-dimensionally and in 2D on the topography of the city through an innovative process of interactive navigation, which can be personalized. The work of digitization and visualization of the data has been carried out with support at 300.000 km/s, and is available online to the whole society and as a tool of help and analysis for any researcher.

The data display shows the number of households, number of public and private buildings or even the number of floors. In addition, the study includes a complete interactive table with all the data analyzed by Ildefonso Cerdá. The table is divided mainly into content and continent, offering a huge amount of data and the existing relationships between both elements.

The work has been carried out in partnership with the Provincial Council of Barcelona, ​​the Generalitat de Catalunya and the Catalan Institute of Soil (Incasol), in addition with the collaboration of the Center for Contemporary Culture of Barcelona (CCCB) and the international foundation Bloomberg Philanthropies.

Among the next projects of is a classification of the different types of urban plot for its recognition by satellite, and the theorization of the universal stages of change of the cities to compare cities that are in different evolutionary stages.
