This paper deals with optimization of splitable resources aimed to the detection of a moving target following a Markovian movement or a conditionally deterministic motion. Our work extends Brown’s spatial optimization method. By use of a generalized linear formalism, we developed a method for optimizing both spatially and temporally (modeling resource renew), with management of multiple resourc...

The development of spatial optimization and simulation techniques in GIS can greatly improve the quality and efficiency of maps generated to pursue spatial pattern objectives in landscape design and planning. This chapter describes how pattern optimization and simulation can be useful in visualizing alternative possible landscapes and for evaluating landscape planning and design scenarios, and ...

BACKGROUND Measurement of healthcare spatial access over a network involves accounting for demand, supply, and network structure. Popular approaches are based on floating catchment areas; however the methods can overestimate demand over the network and fail to capture cascading effects across the system. METHODS Optimization is presented as a framework to measure spatial access. Questions rel...

In this paper, some vital methodological issues of spatial microsimulation modelling for small area estimation have been addressed, with a particular emphasis given to the reweighting techniques. Most of the review articles in small area estimation have highlighted methodologies based on various statistical models and theories. However, spatial microsimulation modelling is emerging as a very us...

Web Feature Service (WFS) is a widely used spatial web service standard issued by the Open Geospatial Consortium (OGC). In a heterogeneous GIS application, a user can issue a query that relates two or more spatial datasets at different WFS servers. Multi-way spatial joins of WFSs are very expensive in terms of computation and transmission because of the time-consuming interactions between the s...
