1. 16. Remote Sensing and GIS : Applications for Groundwater Potential Assessment in Eritrea

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

   Sammanfattning : 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. LÄS MER

3. 17. Analytical tools and information-sharing methods supporting road safety organizations

   Författare :Imad Abugessaisa; Erland Jungert; Kenneth Asp; Åke Sivertun; Josef Mikulik; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Visual data mining; STRADA; GLOBESAFE; Conceptual model; System thinking; Internet GIS; Computer science; Datavetenskap;

   Sammanfattning : A prerequisite for improving road safety are reliable and consistent sources of information about traffic and accidents, which will help assess the prevailing situation and give a good indication of their severity. In many countries there is under-reporting of road accidents, deaths and injuries, no collection of data at all, or low quality of information. LÄS MER

4. 18. Integration of BIM and 3D GIS for sustainable cadastre

   Författare :Jing Sun; Kent Eriksson; Lars Harrie; Jenny Paulsson; Milan Horemuz; Peter van Oosterom; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; BIM; 3D GIS; 3D cadastre; LADM; business ecosystem; cadastre ecosystem; sustainability; Geodesi; Geodesy;

   Sammanfattning : Building Information Modelling (BIM) has prominently innovated and digitalized buildingenvironment through digital representation of buildings, lifecycle process and managementfor involved actors. Rapidly developed from Geographical Information System (GIS) domain,three-dimensionally (3D) GIS provides powerful and comprehensive functions of planning,modelling, visualizing and analyzing 3D geodata in large scale.

5. 19. Spatially Distributed Hydrological Modelling : Wetness Derived from Digital Elevation Models to Estimate Peatland Carbon

   Författare :Abdulghani Hasan; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; modelling hydrology; Digital elevation models; LiDAR data; topographic wetness index; GIS; permafrost; Stordalen; peatland;

   Sammanfattning : To study the hydrology of peatlands and explore wetness distribution is difficultmainly due to the complexity of the surface of peatlands, and also due to the presence of permafrost underlain peatlands in the arctic regions. I have chosen the area called Stordalen mire in the arctic region in northern Sweden for my study. LÄS MER

7. 20. Topological and Scaling Analysis of Geospatial Big Data

   Författare :Ding Ma; Bin Jiang; Shaowen Wang; Högskolan i Gävle; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Third definition of fractal; scaling; topology; power law; head tail breaks; ht-index; complex network; geospatial big data; natural cities; natural streets; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Geographic information science and systems face challenges related to understanding the instinctive heterogeneity of geographic space, since conventional geospatial analysis is mainly founded on Euclidean geometry and Gaussian statistics. This thesis adopts a new paradigm, based on fractal geometry and Paretian statistics for geospatial analysis. LÄS MER
