1. 1. Ontology as Conceptual Schema when Modelling Historical Maps for Database Storage

   Författare :Gustaf Svedjemo; Erland Jungert; Wollter Arnberg; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; HUMANIORA; HUMANITIES; ontology; historical maps; database modelling; GIS; Geographical Information Systems; archaeology; history; ontologi; historiska kartor; databasmodellering; GIS; geografiska informationssystem; arkeologi; historia; Computer science; Datavetenskap; History subjects; Historieämnen;

   Sammanfattning : Sweden has an enormous treasure in its vast number of large-scale historical maps from a period of 400 years made for different purposes, that we call map series. The maps are also very time and regional dependent with respect to their concepts. A large scanning project by Lantmäteriverket will make most of these maps available as raster images. LÄS MER

3. 2. The Use of GIS in Assessing Exposure to Airborne Pollutants

   Författare :Emilie Stroh; Avdelningen för arbets- och miljömedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NOx; air pollution; GIS; Exposure assessment; Lead; NO2;

   Sammanfattning : GIS (Geographical Information System) has become a valuable tool in air pollution exposure assessment studies due to its abilities to accurately model and estimate exposure for large populations and areas. The general aim of the work presented in this thesis was to investigate the factors that affect the validity and precision in the assessment of human exposure to airborne pollution using GIS.

4. 3. A GIS-based landscape analysis of dissolved organic carbon in boreal headwater streams

   Författare :Jan-Olov Andersson; Lars Nyberg; Hjalmar Laudon; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boreal forests; wetlands; vegetation types; headwater streams; catchment hydrology; streamwater chemistry; DOC; GIS; terrain analysis; DEM; slope; wetness index; TWI; Freshwater ecology; Limnisk ekologi; Biology; Biologi;

   Sammanfattning : In boreal catchments, stream water chemistry is influenced and controlled by several landscape factors. The influence of spatially distributed variables is in turn dependent on the hydrological scale. LÄS MER

5. 4. On development of information systems with GIS functionality in public health informatics : a requirements engineering approach

   Författare :Christina Ölvingson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

   Sammanfattning : Public health informatics has in recent years emerged as a field of its own from medical informatics. Since public health informatics is newly established and also new to public health professionals, previous research in the field is relatively scarce. LÄS MER

7. 5. Nature and Culture in Prehistoric Amazonia : Using G.I.S. to reconstruct ancient ethnogenetic processes from archaeology, linguistics, geography, and ethnohistory

   Författare :Love Eriksen; Humanekologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Amazonia; archaeology; linguistics; anthropology; geography; ethnohistory; Arawak; GIS; ethnogenesis; terra preta; pre-Columbian; ethnicity; regional exchange system; material culture;

   Sammanfattning : This thesis investigates the socio-cultural and linguistic development of pre-Columbian Amazonia, with a particular focus on the period between 500 BC and AD 1500. In assembling and analyzing data from archaeology, linguistics, ethnohistory, ethnography, and geography in a Geographical Information System (G.I.S. LÄS MER
