Java Tools for Spatial Analysis
This project was part of an effort to develop a collection of open source Java applets (for use with a web browser) and applications (for freestanding use) to implement exploratory spatial data analysis and spatial regression. A spatial regression Java application (under development) will implement diagnostics for spatial correlation in linear regression models, as well as the estimation of both spatial lag and spatial error models by means of a variety of approaches (maximum likelihood, instrumental variables).
The Java applets implement spatial data analysis in a web environment. They are developed by extending the Geotools open source mapping toolkit. Functionality includes specialized mapping of outliers (box maps), rate map smoothing, and spatial correlation analysis by means of a Moran scatterplot. Development of new tools is ongoing and in part carried out in cooperation with the GeoVISTA Studio project at the Pennsylvania State University.
