Open Source Java Mathematics Software

The JTS Topology Suite is an API for modelling and manipulating 2-dimensional linear geometry. It provides numerous geometric predicates and functions. JTS conforms to the Simple Features Specification for SQL published by the Open GIS Consortium.

Narvik is a tool for conducting numerical and visual analysis in cartography.

Simple UI to test the effectiveness of a heuristic algorithm against the brute force method for path finding among an arbitrary number of arbitrarily placed points on a grid. This is an educational project, don't expect new and better methods.

This software is a time-aware geostatistical tool. Including time variability adds further issues to the already complicated field of geostatistical interpolation. On the other hand, most of the distributions of variables used in Earth and environmental sciences show patterns of change over time, not only in space. This tool is a free, open-source software, based on a generalization of the Inverse Distance Weighted algorithm. It outputs three-dimensional, layered discrete models from which time series and equal-time GIS Grid layers can be extracted.
