1. Modeling and improving Spatial Data Infrastructure (SDI)
Sammanfattning : Spatial Data Infrastructure (SDI) development is widely known to be a challenging process owing to its complex and dynamic nature. Although great effort has been made to conceptually explain the complexity and dynamics of SDIs, few studies thus far have actually modeled these complexities. LÄS MER
2. Data-driven models for railway track geometry maintenance
Sammanfattning : Railways are currently experiencing higher demands on safety, infrastructure performance, network capacity and service quality, etc. As a result, a high level of track availability, service quality and infrastructure robustness against unexpected events is required, at reduced cost, to meet the demands.

3. Methods to Improve and Evaluate Spatial Data Infrastructures
Sammanfattning : This thesis mainly focuses on methods for improving and evaluating Spatial Data Infrastructures (SDIs). The aim has been threefold: to develop a framework for the management and evaluation of an SDI, to improve the accessibility of spatial data in an SDI, and to improve the cartography in view services in an SDI.

4. Investigating Spatial Data Infrastructure Planning in Tanzania using System Modelling and Social Concepts
Sammanfattning : Spatial Data Infrastructure is one of the requirements for sustainable development and many countries worldwide are at different stages of implementation. Several researchers have shown that SDI has helped governments to recover funds due to reduction in duplication of efforts and also has increased efficiency in resource management and planning.

5. Geographical Information Technologies – Decision Support for Road Maintenance in Uganda
Sammanfattning : This study set out to develop a framework within which the use of Geographical Information Technologies (GITs) can be enhanced in Road Infrastructure Maintenance (RIM) in Uganda. Specifically it was guided by 3 objectives; 1. To assess the gaps in the use of GITs for RIM in Uganda and the limitations to accessing these technologies, 2. LÄS MER
