A graph G is called a pairwise compatibility graph (PCG) if there exists an edge weighted tree T and two non-negative real numbers dmin and dmax such that each leaf lu of T corresponds to a vertex u ∈ V and there is an edge (u, v) ∈ E if and only if dmin ≤ dT (lu, lv) ≤ dmax where dT (lu, lv) is the sum of the weights of the edges on the unique path from lu to lv in T . In this paper we analyze...

Strain is an important parameter for assessing the potential impacts resulting from mine subsidence movements. However, strain resulting from mine subsidence is also one of the most difficult parameters to predict accurately. A number of methods can be used to predict strain, from simple empirical relationships, to more complex statistical approaches. This paper looks at some of these predictio...

A graph G = (V, E) is called a pairwise compatibility graph (PCG) if there exists a tree T , a positive edge-weight function w on T , and two non-negative real numbers dmin and dmax, dmin ≤ dmax, such that V coincides with the set of leaves of T , and there is an edge (u, v) ∈ E if and only if dmin ≤ dT,w(u, v) ≤ dmax where dT,w(u, v) is the sum of the weights of the edges on the unique path fr...

This paper describes a Web-based query system for semantically heterogeneous geospatial data. Our goal is to provide DBMS type query capabilities to a proposed statewide land information system. One of the main problems in querying distributed local data sources is the difference in semantics describing the characteristics (attributes) of spatial objects between various jurisdictions. To addres...

In this paper, we explore the interaction between taxation and local public good (LPG) and how it impacts the spatial pattern in the framework of new economic geography (NEG). In the benchmark case of a pure LPG, the system displays a similar location pattern to the existing NEG taxation model, although the tax reduces the market size of manufactured goods. However, when we consider the inheren...

This paper shows how standardization activities are progressing and contributing to the fact that Land Administration (LA) is considered more and more the cornerstone of the spatial information infrastructure. This is equally valid for regional, national, continental, and global levels, as will be illustrated in this paper. The paper describes the involved organizations and the current status o...

Future directions for spatial information management in Australia, from a land administration perspective, are discussed. Sustainable development, micro-economic reform, globalisation and technology are highlighted as the drivers for change. The changing spatial information environment with emphasis on land administration and cadastral issues is examined by drawing on research being undertaken ...
