Collaborative GIS Environment for Exploratory Spatial Data Analysis Based on Hybrid P2P Network

摘要

We propose a method of applying P2P network to collaborative GIS environment, particularly targeting exploratory spatial data analysis for small-group brainstorming. Under the hybrid P2P network, we implement and integrate two core components for collaborative GIS environment: P2P GIS super-node and client-node. Using these core components, we build a collaborative GIS application for the exploratory spatial data analysis to discover distribution patterns and spatial associations of geographical phenomena in cooperative way.
