Vienna´s 1st municipal district is an area dense with built heritage. A public map created in Google Maps shows the location of heritage building protection. It combines open data provided by the City of Vienna and the Federal Monuments Authority. The map has two functions: first, the map holds information on the 669 individual buildings that are protected according to the Austrian Monuments Law, providing information on the individually protected buildings in five layers. Among these layers, one shows the location of these buildings without further discrimination, while another layer shows whether buildings are protected by legal presumption or by decree. Additional layers show building characteristics such as the number of storeys, original roofs and use. By clicking on a building in any layer, additional building information appears on the left-hand side of the browser window, including alternate addresses, year of construction and architect. The second function of the map is to show different legal protection areas, such as the UNESCO World Heritage site "Historic City Centre of Vienna" and the "Protected Zones" according to the Building Code for Vienna. Viewers can choose between three layers visualizing the core and buffer zones of the World Heritage site, protected zones and the ensemble "Vienna City Centre". By selecting multiple layers at once, viewers can see where areas overlap and buildings therefore enjoy triple legal protection, but can also instantly locate gaps where this is not the case. The map visualises the complex legal construct that protects the built heritage in Vienna. It allows viewers to easily identify areas with dense legal protection and in addition provides easily accessible information on listed buildings.
