Geographic Information Systems

Geographic information science (GIS) research focuses on the analysis of spatial relationships, defining uncertainty, and using GIS for decision-making.

Total global ecosystem services from Watson (2017).

Mapping global ecosystem services 

This ongoing research builds on the work pioneered by Costanza (Nature, 1997) and aims to further update and present terrestrial and marine ecosystem services on a global scale. Further work will assess the uncertainty of the input data sets in order to better assist decision-making from the analysis.

Fuzzy logic multi-criteria evaluation 

A fuzzy logic multi-criteria evaluation and error propagation analysis methodology has been proposed for petroleum exploration. Further work will assess the applicability to a variety of geographic regions as well as improving the uncertainty of input data sets.

Conjugated Basins, Tectonics, and Hydrocarbons (CBTH)

 A regional basin study focusing on the Gulf of Mexico, Caribbean, northern South America, and western Africa that provides a GIS database of original and digitized geologic and petroleum data. The database consists of seismic, well, cross section, stratigraphic column, and outcrop data as well as a geologic database combined for consistent attribute classification and sourceability. Key personnel: Paul Mann (UH) and Alejandro Escalona (UiS)

Lower Cretaceous Basin Studies in the Arctic (LoCrA)

 A regional basin study that focuses on the Lower Cretaceous in the Norwegian and western Russian Arctic that provides a GIS database of original and digitized geologic and petroleum data. The database consists of seismic, well, cross section, stratigraphic column, outcrop, palynology, and provenance data as well as a geologic database combined for consistent attribute classification and sourceability. This project was concluded in 2018. Key personnel: Snorre Olaussen (UNIS) and Alejandro Escalona (UiS)
