    Advanced Procedure for the Monitoring of Settlement and Open Space Development on Basis of Topographical Geodata Sets in the IOER-Monitor
    (Innovations in Sharing Environmental Observations and Information, 2011) Meinel, Gotthard
    A concept and the first results of the Monitor of settlement and open space development are presented. The monitoring system will describe the state and the development of land use especially in regard to its sustainability for the entire Federal Republic of Germany. To this end, for the first time ever it makes use of topographical geobasis data (digital landscape model of the Authoritative Topographic-Cartographic Information System. These data allow for a more precise spatial and content-wise description of land use than that of the land register data, which serve as the basis for the official land use statistics. On the basis of the geobasis data an automatic calculation of indicators from the fields of settlement, open space, nature reserves, population and traffic occurs. The indicators are depicted in thematic maps, thus allowing for spatial and chronological comparisons. In addition to administrative spatial units (federal state, district, municipality), the indicator values are also presented in scales of various cell widths. For calculating building-based settlement indicators, the patented program SEMENTA© is used, which is based on an automated evaluation of analogue maps.

    Analyse und Visualisierung von Verstädterungsprozessen mit Hilfe von Geoinformationssystemen am Beispiel der Flächenentwicklung Dresdens
    (Umweltinformatik ’00 Umweltinformation für Planung, Politik und Öffentlichkeit, 2000) Meinel, Gotthard; Gössel, Jörg; Heber, Bernd; Hennersdorf, Jörg; Siedentop, Stefan
    Objective of the project MURBANDY (Monitoring Urban Dynamics) was to establish a long-term monitoring of land use development. For four time slots a polygon and a line dataset has been derived representing land use units and linear infrastructure features. The compilation of the land use and transport coverages was based on computer assisted visual interpretation of the image data. The resulting data-bases will be primary used to identify spatial patterns of urban growth, but they also help understanding temporal pathways of urbanization.

    Full Automatic Calculation of Settlement Structure on Base of Topographic Raster Maps
    (Environmental Informatics and Industrial Ecology, 2008) Meinel, Gotthard
    The paper describes a method for full automatic calculation of settlement structure on base of simple topographic raster maps. In a first step extracted all buildings, they are mixed with streets, scripts and signatures in the maps. After vectorization we calculated building variables such as area, length, width, shape complexity and distance to next building. On base of this description we classified all buildings and realized a statistical analysis on building block level. We estimated 16 indicators (e. g. building and inhabitant density), visualized indicators in a GIS in optimized pre-defined legends and calculated a statistical report for the study area in different spatial resolution. The full automatic procedures called SettlementAnalyzer (SEMENTA®) have been implemented in ArcGIS under additional using of the image processing software HALCON.

    Provision of Recreational Areas in Urban Spaces— An International Long-Term Comparison of the Development s of Selected European Cities
    (The Information Society and Enlargement of the European Union, 2003) Meinel, Gotthard; Winkler, Michael
    Open spaces and in particular recreational areas are for many reasons a very important factor for the quality of life of the urban population. Based on GIS data sets for the cities of Bilbao, Bratislava, Lyon, Dresden and Palermo from the EC-projects MURBANDY/ MOLAND 2 analyses were carried out to show the development of the provision of recreational areas and the quality of their reachability within these cities during the past 50 years. The presented paper aims at measuring possible deficits and comparing trends within the analysed cities. Freiräume und insbesondere Erholungsflächen sind hinsichtlich vieler Gründe sehr wichtig für die Lebensqualität der städtischen Bevölkerung. Basierend auf GIS-Datensätzen für die Städte Bilbao, Bratislava, Lyon, Dresden und Palermo aus den EU-Projekten MURBANDY/MOLAND wurden Analysen, die die Entwicklung der Untersuchungsstädte bezüglich ihrer Ausstattung mit Erholungsflächen und deren Erreichbarkeit innerhalb der vergangenen 50 Jahre aufzeigen, durchgeführt. Der vorliegende Artikel beleuchtet mögliche Defizite und vergleicht die Entwicklungen innerhalb der analysierten Städte.

    Spatial Data Infrastructures and Data Mining – An Introduction
    (Environmental Informatics and Industrial Ecology, 2008) Thinh, Nguyen Xuan; Meinel, Gotthard
    Spatial data infrastructures (SDIs) and data mining have been a key challenge of a modern society. SDIs as well as spatial data mining should become a topic of the annual conference EnviroInfo. The main objectives of our paper are: (1) To provide a short overview about spatial data infrastructures (definitions, goals, hierarchy of SDIs, and relations to other initiatives). (2) To describe the three main data mining techniques which have been often used for spatial datasets. (3) To report on the development of a spatial database at the Leibniz Institute of Ecological and Regional Development (IOER) for the key research area “Settlement and Open Space Development Monitor” and to illustrate some applications of the spatial data mining in selected IOER projects such as “Research to Ecological and Economic Performance Potentials of 116 German Regional Cities.
