This thesis deals with the of problems of GIS-use in urban administrations. It describes the use of GIS and spatial reference systems in urban administrations. Apart from the GIS in Düsseldorf, the use of GIS in Stuttgart, Wuppertal, the Lower-Rhine Region, and Vienna are characterized.
The need for spatial data for administrative performances on the part of the urban administrations in Germany constantly increases. Therefore, it is not anymore about the question: GIS, yes or no? Using GIS in urban administrations is self-evident nowadays, almost every commune uses GIS.
Today, a huge amount of geo-data is available in many different departments of urban administrations. Concerning the programs used to maintain the data and work with it, the different datasets, their underlying data model, and the seldom available meta-data it is clear to see, that this field of applications is very diverse. This diversity is not only characterized by a multiplicity of programs, datasets, and data models, but also by differing geometrical quality. These differences in the data quality are either due to differing data coverage procedures, or due to a loss of information during converting data.
Several urban administrations tried to rectify the problems that derived from this diversity. In Vienna for example, a completely new system was established that integrates all other GIS used before.
Other cities started to renew their GIS and spatial reference systems for the same reason. Düsseldorf however, is a city that till now did not replace its current system.

Objectives & Core Topics
The primary objective of this work is to assess the complex GIS landscape within Düsseldorf's urban administration and to formulate recommendations for systemic improvements, specifically by leveraging successful models from other municipalities and insights from expert interviews.
- Analysis of existing GIS structures and inter-departmental workflows in Düsseldorf.
- Evaluation of the MERKIS recommendation as a standard for communal information systems.
- Benchmarking GIS implementations in Stuttgart, Wuppertal, the Lower-Rhine Region, and Vienna.
- Identification of core obstacles such as data heterogeneity, lack of interoperability, and maintenance challenges.
- Proposal of optimization strategies including shared network graphs and geo-data warehouse concepts.
Book Excerpt
3.2.2 Structure of Düsseldorf’s GIS
All departments of Düsseldorf’s administration are urged to use MapInfo as their GIS. But to match the needs of some departments, further programmes are necessary. As explained in chapter 2, the requirements of an exemplary department were examined in several interviews. The structures of the distinct GIS in use in this department differ and present themselves as follows.
Every department provides important data to a particular network drive. Thus, exchanging data between departments is assured. Listed here are some exemplary layers: Traffic lanes, main street network, street names, network classifications, diverse city maps, aero photos with varying scales, land development plan, realty maps, street and traffic cadastre, Rest homes, Waste containers, Statistical blocks, Industry data, data on buildings (Adapted from Fantasny 2009).
However, the data provided is meant to be used with MapInfo, which doesn’t meet the demands of all tasks in the departments. That means that all departments try to combine their data with other systems to complete the set of necessary applications essential to carry their tasks.
Summary of Chapters
1. Introduction: This chapter highlights the increasing necessity of GIS in German urban administrations and introduces the specific challenges regarding data diversity and quality in Düsseldorf.
2. Course of Investigation: The author details the research methods employed, including interviews with experts in Düsseldorf, Vienna, and the KRZN, and provides key definitions for GIS-related terminology.
3. Spatial Reference Systems in Urban Administration: An overview is given of the MERKIS recommendation and the diverse GIS implementation strategies observed in various German and Austrian municipalities.
4. Requirements in Düsseldorf: This section investigates the operational tasks of the traffic planning department and highlights critical functional requirements and existing limitations within the current GIS setup.
5. Possible System Improvements: The author evaluates potential enhancements, such as shared network graphs and geo-data warehouses, while addressing the significant obstacles to the realization process.
6. Conclusions and Recommendations: The final chapter summarizes findings and provides pragmatic recommendations for upgrading Düsseldorf’s GIS by focusing on incremental improvements rather than full-scale system replacements.

Frequently Asked Questions
What is the core focus of this research?
The research examines the implementation and usage of Geographic Information Systems (GIS) within the urban administration of Düsseldorf, identifying current structural issues and exploring improvement strategies based on external benchmarks.
Which thematic areas are covered?
The work covers GIS terminology, municipal spatial reference standards (MERKIS), comparative studies of GIS in other cities, user requirements, and technical challenges like system compatibility and data maintenance.
What is the primary research goal?
The primary goal is to provide actionable recommendations for improving Düsseldorf's fragmented GIS environment, specifically by addressing issues in inter-departmental data exchange and systemic integration.
Which scientific methodology is applied?
The author utilizes a qualitative approach, combining literature review with problem-oriented, semi-structured interviews conducted with employees involved in GIS management across several administrations.
What topics are discussed in the main body?
The main body focuses on the current state of GIS in Düsseldorf, detailed requirements from traffic management departments, and an analysis of how other cities solve similar integration problems.
How is the work characterized by keywords?
The work is defined by terms such as interoperability, spatial reference, municipal geo-data infrastructure, and administration-specific technical requirements.
What are the specific challenges of the system in Düsseldorf?
The system is described as extremely heterogenic and complex, suffering from imprecision in spatial reference, dated software, lack of common data standards, and difficult inter-departmental communication.
Why are meta-databases considered important for improvement?
Meta-databases are proposed as a crucial, low-cost solution to improve transparency and data usage across departments, helping users locate and understand the quality and purpose of available geo-data.
