A critical infrastructure (CI) is an array of assets and systems that, if disrupted, would threaten national security, economy, public health and safety, and way of life. Essential to the practice of critical infrastructure planning and drills are two pieces of knowledge. One concerns the...

Agent-based models offer a promising framework for analyzing interactions between agents and a heterogeneous landscape. Researchers have identified a complex of factors that influence exurban development, including demographic shifts and location attractiveness of natural amenities as a magnet...

People experience and memorize space primarily with the help of landmarks. These landmarks have structural salience, besides visual and semantic salience. When people move in urban space they perceive first the street network as structuring this space. Therefore, streets are a good candidate for...

Following half a century of breakneck urbanization, the capital of South Korea emerged in the late 1990s as the most digitally networked city in the world. With nearly 80% household broadband penetration in 2004, Seoul surpassed global cities and ‘technopoles’ in speed and comprehensiveness...

This paper focuses on problems and their causes and cures in policy and planning for large-infrastructure projects. First, it identifies as the main problem in major infrastructure developments pervasive misinformation about the costs, benefits, and risks involved. A consequence of...

Axial analysis is one of the fundamental components of space syntax. The space syntax community has suggested that it picks up qualities of configurational relationships between spaces not illuminated by other representations. However, critics have questioned the absolute necessity of axial...

Timber-harvesting operations, especially clearcutting (that is, harvesting operations where all of the trees in a given area are removed), have been criticized for many reasons, not least of which is their unsightly appearance. Forest managers have recognized this, and have attempted to place...

Agent-based modeling and simulation (ABMS) has been a part of geospatial sciences for over a decade. Most research activities so far have concentrated on either extending complexity theory to spatially explicit phenomena, or on designing computational models and software tools. Only a few of...

The recent development of web-based services that combine spatial coordinates and indexes of online material allows any web user to conduct geographically referenced Internet searches. In this paper we characterize the resulting hybrid space as DigiPlace—that is, the use of information ranked...
