Exploring spatial growth pattern of informal settlements through
Agent-based simulation
This research has explored the use of agent-based model for studying the spatial growth pattern of informal settlements in Mbagala, Ukonga and Kawa wards of Dar es Salaam, Tanzania from 1992 to 1998. A spatially explicit agent-based model is developed by adjusting an existing model (Economic disparity model) to incorporate the spatial physical structures of an urban area. The ABM is developed based on the locational decision making of people that develops into three major growth pattern of informal settlements: spontaneous growth, linear (road influenced) development and Infilling & outward spread. Emphasis is made on how to include the urban spatial physical structure into the model, and how the behavior of different income group of people translates into specific growth pattern.

Definition of future Commercial Land Use Patterns based on an
Analytical
This thesis examines the subjects of locational decisions and land use patterns
evolution. Statistical methods, distance based techniques and GIS spatial analysis
used in order to develop a methodology for proposing the future commercial use of a
retail store placed within the commercial business district of a city. Spatial
interactions explored between the different types of retail stores and estimations
made for the future commercial land uses of stores given their locations. The
research ends with the description of the spatial structure of the commercial business
district of Volos city in a future time as through the processes of the methodology all
the empty stores of the area assigned to one of the existing commercial uses.

Developing an Environmental Fog Potential Map using a GIS
The Environmental Fog Potential Map (EFPM) is the spatial representation of the EFP Index (EFPI), an index that expresses the potential occurrence of radiation fog at a location. The main objective of the thesis was to develop and validate the EFPI.
This was done by the following steps:
1. Determination and selection of the factors that contribute to radiation fog.
2. Development of a conceptual model for the EFPI.
3. Implementation of the EFPI in ArcGIS.
4. Calibration and consecutive validation of the index.
Due to limited availability of calibration data the EFPI was validated for limited conditions only.
Recommendations on further development and improvement of the EFPI have been made. The
conditionally validated EFPI was used for the production of the EFPM for an area around Amsterdam airport.
