1. Methodology for creating and modifying distributed topologically structured geographical datasets
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap; Lunds universitet/Lantmäteri (CI)Sammanfattning : Spatial relationships are a comprehensive and essential part of geographical information management and GIS. Topological relationships are a subgroup of the spatial relationships. They are defined by the fact that they do not break under topological transformations, meaning they remain when stretching, twisting or crumbling the underlying space. LÄS MER
2. Automatic creation of schematic maps : a case study of the railway network at the Swedish Transport Administration
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Idag vill man effektivisera användningen av geografiska informationssystem (GIS), vilket uppmuntrar järnvägsförvaltningarna att centralisera sina data. Därför hämtar de både geografiska och schematiska framställningar från samma databas. LÄS MER
3. Urban land-use planning using Geographical Information System and Analytical Hierarchy Process : case study Dhaka city
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Urban land-use planning, which is a useful tool for the sustainable development of a city, is a complex decision making process. However, the modern GIS technologies facilitate such complex jobs in two ways – (i) GIS allows to work with large numbr of datasets, (ii) a number of methods, techniques or models could be embeded in GIS for land-use suitability analysis.

4. A Topologically Aware Resource Management System
Master-uppsats, KTH/Radio Systems Laboratory (RS Lab)Sammanfattning : As companies fight for market share whoever is able to bring products to market faster has an advantage over their competitors. Therefore it is absolutely essential to constantly evaluate and optimize processes to achieve shorter time-to-market for products. These optimizations have to be carried out in all parts of a company. LÄS MER
5. Schematic representation of the geographical railway network used by the Swedish Transport Administration
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : Today, one of the needs of the railway information systems is sharing the precise and exact data among varieties of stakeholders. In addition, efficient use of Geographical Information Systems (GIS) encourages the railways administrations to centralize their data and prepare an information model whose purpose is to reduce the demands associated with the transformation of the data.
