2. 1. Making 21st Century Maps Legible - Methods for Measuring and Improving the Legibility and Usability of Real-Time Maps

   Author : Hanna Stigmar; Fastighetsvetenskap; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The research presented in this thesis has focused on methods for improving the legibility and usability of maps in real-time map services. The aim has been threefold: to create methods to increase the cartographic quality of maps in map services, to develop methods to measure the legibility, as perceived by the user, and to evaluate the quality of maps.

4. 2. Modelling, mapping and visualisation of flood inundation uncertainties

   Author : Nancy Joy Lim; Stefan Seipel; S. Anders Brandt; Eva A. U. Sahlin; Matthew Wilson; Högskolan i Gävle; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cartography; flood; hydraulic modelling; GIS; map; uncertainty; visualisation; GIS; hydraulisk modellering; karta; kartografi; osäkerhet; visualisering; översvämning; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Flood maps showing extents of predicted flooding for a given extreme event have wide usage in all types of spatial planning tasks, as well as serving as information material for the public. However, the production processes that these maps undergo (including the different data, methods, models and decisions from the persons generating them), which include both Geographic Information Systems (GIS) and hydraulic modelling, affect the map’s content, and will be reflected in the final map.

6. 4. Discrete-Time Cellular Neural Networks Implemented on Field-Programmable Gate-Arrays to Build a Virtual Sensor System

   Author : Suleyman Malki; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellular Neural Networks; Image processing; Discrete-Time Cellular Neural Networks; Packet switching; FPGA; Velocity measurement; Autowaves; Robot navigation;

   Abstract : Image processing is one of the popular applications of Cellular Neural Networks. Macro enriched field-programmable gate-arrays can be used to realize such systems on silicon. At first glance a pipelined approach, based on circuit switching, seems promising. READ MORE

7. 5. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea

   Author : Semere Solomon; KTH; []
   Keywords : Remote sensing; Geographic Information Systems; groundwater; geomorphology; Digital elevation model; lithology; hard rock; lineament; structures; hydrogeology; Eritrea;

   Abstract : An integrated approach with remote sensing, GeographicInformation Systems (GIS) and more traditional fieldworktechniques was adopted to assess the groundwater potential inthe central highlands of Eritrea. Digitally enhanced colorcomposites and panchromatic images of Landsat TM and Spot wereinterpreted to produce thematic maps such as lithology andlineaments. READ MORE
