It’s all about the map!\r\nFlood hazards and standard land values available in the new map manager<\/h2>\r\nTo kick off the new year, we already have a number of new services to announce on IZ Research. In the January release, it’s all about the map. With the live launch of the flood hazard map and the standard land value map, we are further expanding the map scope on IZ Research. We are also introducing the new map manager as an intuitive tool for searching and displaying theme and background maps.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Standard Land Value Map<\/h3>\r\nThe new standard land value map provides easily accessible standard land values for all federal states and city states in Germany in which the real estate valuation committees have joined the OpenData Initiative of the Federal Government (https:\/\/www.govdata.de\/dl-de\/by-2-0<\/a>). First, we are starting with all municipalities in North Rhine-Westphalia and Thuringia. Lower Saxony has been live since 1st March 2023, Hesse since 24th Mai 2023. The standard land value maps for Brandenburg, Bremen, Berlin, Hamburg, Hesse and Lower Saxony will be added in the next few weeks. You can then view the standard land values determined by the regional valuation committees (in accordance with \u00a7193 para. 5 BauGB) centrally on one map.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Flood hazard map shows the extent of flooded areas for the whole of Germany<\/h3>\r\nRiver floods or floods originating from the sea are natural events. River floods occur regularly and with fluctuating intensity and are typical of the discharge behaviour of rivers. The intensity of floods depends on the intensity and duration of precipitation, the characteristics of the catchment area and the special features of the river. With increasing building development near rivers and the straightening of river landscapes, the floodplain landscapes have disappeared in many places and the rivers have been deprived of their natural floodplains.\r\n\r\nDue to climate change, flooding frequency in Germany is already increasing and will continue to do so in the future. In particular, heavy rain is causing rivers and streams to repeatedly burst their banks, and extreme weather in coastal regions is also becoming more frequent.\r\n\r\nAccordingly, it is important that cities and municipalities, property owners and project developers are aware of these hazards and take appropriate precautions against environmental risks. With the implementation of the flood hazard map in IZ Research, we would like to provide our clients with an important source of information for risk assessment.\r\n\r\nThe flood hazard map<\/strong> shows the extent of the inundation areas during floods depending on the frequency of a flood event. The extent of flooding and the frequency of flooding in the affected areas are used to calculate the probability of flooding.\r\n\r\nThe data on flood-prone areas are based on nationally homogenised data sets provided by the Federal Institute of Hydrology and defined by Directive 2007\/60\/EC of the European Parliament and of the Council of 23 October 2007 on the assessment and management of flood risks.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
