Visual topology in SDI: a data structure for modelling landscape perception
Visual Topology is a used here to describe the spatial relations between objects as they appear in the 2D viewing plane. This thesis sets out the concept, explains why it is needed in Geographic Information Science and suggests how it may be computed through development of prototype …

A new trajectory for spatial data infrastructure evolution in the developing world
… available for use. Spatial Data Infrastructures (SDIs) have served this primary purpose; to make data accessible through the use of web based technologies. However, SDIs have not had their anticipated impact at local levels of governance. They have traditionally served as platforms that facilitate …

An exposition of the nature of volunteered geographical information and its suitability for integration into spatial data infrastructures
… for use in a spatial data infrastructure (SDI) to supplement official and commercial sources, particularly given the ease with which ordinary people can document their environment, experiences, perspectives and prejudices, share them widely and rapidly, and even query anyone else?s content. …

Structural Performance of Fiber-Reinforced and Welded Wire Fabric-Reinforced Concrete Composite Slabs
… Engineers (ASCE) and the Steel Deck Institute (SDI). The flexural strength tests showed that composite slabs reinforced with synthetic macro fibers and WWF exhibited strength and behavior that was almost identical. The observed values of strength were also within the range that was predicted by …

The Ladle and the Knife: Power Projection and Force Deployment under Reagan
… Reagan’s defense spending surge, “Star Wars” (SDI) missile shield policy, and 1983 invasion of Grenada gave the president confidence and political cover that allowed him to withdraw U.S. Marines from Beirut in early 1984. Analysts and commentators focus on his muscular power projection like …

Development of Planning Support Systems in the European context
… the development of Spatial Data Infrastructures. SDI offer new opportunities to planners for supporting decision-making in sustainable spatial planning, through a wealth of interoperable spatial data and services which are for the first time, given public access. Although with the SDI the role of …
