2. 1. An Optimisation Approach to Cartographic Generalisation

   Author : Lars Harrie; Centrum för geografiska informationssystem (GIS-centrum); []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; incremental generalisation; multiple representation; least-squares method; optimisation; cartographic constraints; displacement; cartographic generalisation; graphic generalisation; map production; object-oriented spatial databases; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik;

   Abstract : Cartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. READ MORE

4. 2. Generalisation Methods for Propagating Updates between Cartographic Data Sets

   Author : Lars Harrie; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiple representation database; automated cartographic generalisation; incremental generalisation; displacement; cartographic constraints; object-oriented database;

   Abstract : Automation is increasingly important in producing and maintaining cartographic data sets. This thesis deals with automatic methods to propagate updates between cartographic data sets. READ MORE

   Abstract : Geographic information is one of the most important and the most common types of information in human society. It is estimated that more than 70% of all information in the world has some kind of geographic features. READ MORE

6. 4. Visualisation and Generalisation of 3D City Models

   Author : Bo Mao; Yifang Ban; Lars Harrie; Monika Sester; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D city models; visualisation; generalisation; multiple representation structure; similarity evaluation; aggregation; typification; shell model; street index; texture compression; texture segmentation; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Abstract : 3D city models have been widely used in various applications such as urban planning, traffic control, disaster management etc. Efficient visualisation of 3D city models in different levels of detail (LODs) is one of the pivotal technologies to support these applications. READ MORE
