    Building and demographic development of Prague suburbs in the work of Alfred Hurtig, by Eva Novotná
    At the end of 19th century Prague was rapidly developing due to the process of industrialization. The demolition of the city walls enabled gradual connection of Prague and its suburbs. Redevelopment of Josefov, Old and New Town changed the character of poor quarters into luxurious districts with broad streets. A. Hurtig, as a head surveyor of Building Authority of the Capital City of Prague, published topographic plans of Prague and its outskirts on a large scale. These reflected not only new administrative arrangements and captured the current state of the city, but also contained building plots and planned or later realized constructions of streets and residential areas. The plans used to be supplemented with demographical data, which reflected dynamic growth of Prague’s suburbs. The city development is documented in Hurtig’s plans not only through the housing construction but also with the infrastructure and social amenities. The paper presents examples of this development using the case study of Královské Vinohrady district. The Greater Prague factually came to be in 1922.

    Vulnerability to extreme temperatures: shall we expect to live in hot cities? by Simeon Vaňo, Petr Bašta, Lenka Suchá, Jan Geletič, Martin Jančovič, Helena Duchková
    Climate change and especially extreme heat represent an unprecedented challenge for cities, threatening future prosperity, health and wellbeing of urban populations. Climate adaptation is therefore one of the central topics for sustainable cities and societies. This article introduces a methodological approach for assessment of urban population vulnerability to extreme heat until the year 2050, presented on the example of the city of Brno. The assessment, based on the variety of future climate and socioeconomic scenarios and on the extent of implementation of adaptation measures, led to identification of vulnerable localities across the city. Results suggest that global climate scenarios, extent of built up area and population density have major effects on overall vulnerability to extreme heat, although extensive implementation of adaptation measures can reduce vulnerability substantially. The introduced vulnerability assessment represents an important tool in support of urban planning, as it provides complex data on possible future developments including adequate adaptation options.

    The potential of development sites for efficient rainwater management in urbanized territories, by Jan Kopp, David Vogt, Tomáš Hejduk, Radek Roub and Filip Urban
    The aim of this article is to specify five basic types of urban development sites in terms of rainwater management and conditions for projects for rainwater management systems. In part, preconditions for an ideal rainwater management system have been taken from a statistical analysis of detailed site cover structure in a model territory in the city of Plzeň. The mean values of site cover representation have been used to calculate the environmental parameters characteristic of particular types of functional use. Knowledge of literature on functional urban areas in the context of climatic and hydrological conditions has also been taken into account in order to identify the rainwater management potential of various territories. The article includes a discussion on the property share of municipalities in various types of territories and its impact on advances in suitable systems of rainwater management. A summary of the results, enhanced by knowledge of available typologies, will inform the creation of software and methodology to support rainwater management measures and tools that the state administration will use to apply them.

    A system of documentation for conceptual rainwater management in municipalities, by David Stránský & Ivana Kabelková
    At the behest of the Ministry of the Environment, the Czech Water Association has produced the Analysis of Documents for Conceptual Rainwater Management in Municipalities, the main purpose of which was to analyse the documents necessary for rainwater management in the context of urban planning and provide groundwork for the operational programme Environment in terms of financial support for these documents. In describing this analysis the article is complemented by Standards of Rainwater Management in the Territory of Prague, a conceptual document focused on objectives, principles, priorities, obligatory parameters, proposal procedures and construction principles of rainwater management on Prague construction sites. The procedure for implementation of these standards in construction practice in Prague is also described.

    Monument preservation for the purpose of spatial analysis, by Alena Krusová & Zuzana Syrová-Anýžová
    The National Heritage Institution has been running the Geoportal of Monument Preservation, making available territorial data for the purpose of spatial analysis, since January 2016. The mapping services and applications of the Geoportal facilitate instantaneous awareness of the current state of data in any territory. These data are provided to registered and authorized users in the form of digital output in standard formats. Besides data provided by the National Heritage Institution in accordance with the Building Act (i.e. spatial data from the Central List of Cultural Monuments in the Czech Republic and the State Archaeological List of the Czech Republic), the Geoportal and other applications of the Integrated Information System of Monument Preservation are sources of information on architectural and urban planning values in territories. This article provides basic facts on monument information systems, their history, data structure, links within the key applications of the Integrated Information System, and spatial and non-spatial data applicable in spatial planning.
