Network data structures were one of the earliest representations in geographic information systems (GIS), and network analysis remains one of the most significant and persistent research and application areas in geographic information science (GIScience). Network analysis has a strong theoretical basis in the mathematical disciplines of graph theory and topology, and it is the topological relat...

Introduction Geographic information systems (GIS) are not exactly new to the social sciences—the UK's Economic and Social Research Council funded a network of GIS-based laboratories at UK universities in the late 1980s and early 1990s, and the U.S. National Science Foundation's Directorate for Social, Behavioral, and Economic Sciences funded the National Center for Geographic Information and An...

Querying and analyzing large volumes of spatially oriented scientific data becomes increasingly important for many applications. For example, analyzing high-resolution digital pathology images through computer algorithms provides rich spatially derived information of micro-anatomic objects of human tissues. The spatial oriented information and queries at both cellular and sub-cellular scales sh...

The significant objective of this paper is to describe how Cellular Automata (CA) can be used to predict land use land change in the settlement growth and show the advantage of integrating the Neural Network with CA. Cellular automata have been utilized as a prediction technique in the study of an impressively wide range of dynamic phenomena. A spatial simulation model comprises an assortment o...

As a plant shoot matures, it transitions through a series of growth phases in which successive aerial organs undergo distinct developmental changes. This process of phase change is known to be influenced by gibberellins (GAs). We report the identification of a putative transcription factor, GLABROUS INFLORESCENCE STEMS (GIS), which regulates aspects of shoot maturation in Arabidopsis thaliana. ...

In this paper, a discussion of employing Global Positioning System (GPS) and geographic information system (GIS) technologies for packet routing strategies in ad hoc mobile wireless networks is presented. Mobile network architectures and existing packet routing schemes are briefly discussed to illustrate how GPS and GIS techniques can be beneficially employed. Telegeoinformatics, a new discipli...

We present a viable geometric solution for the detection of dynamic effects in complex networks. Building on Forman’s discretization of the classical notion of Ricci curvature, we introduce a novel geometric method to characterize different types of real-world networks with an emphasis on peerto-peer networks. We study the classical Ricci-flow in a network-theoretic setting and introduce an ana...
