...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.

A geolocation code for Ireland and elsewhere. Fully extensible. Encoding coordinates into single base-25 characters.

A new algorithm for extracting roof tops was developed. Using the assumption that roof tops are planar in construction, a new approach was developed using volume of point clouds to determine whether a cluster contains planar points. This approach yields very promising results and with attention applied to its weaknesses, should provide another algorithm which can rival currently available roof top detection methods.

The Java RTree project aims to maintain an Java version of the RTree spatial indexing algorithm. See http://jsi.sourceforge.net for more information, and http://github.com/aled/jsi for latest development code.

The C# RTree project aims to maintain a C# version of the RTree spatial indexing algorithm. Ported from https://sourceforge.net/projects/jsi

MCC-LIDAR is a C++ application for processing LiDAR data in forested environments. It classifies data points as ground or non-ground using the Multiscale Curvature Classification algorithm.

GISpatialNet is a Java-based tool for mapping network data (nodes and edges between them) to spatial coordinates; reformatting network and spatial data together; and calculating spatial network measures. Install by saving to c:\ drive and typing the following in a command line: java -jar c:\GISpatialNet-0.9b.jar

A disk based production quality RTree based upon Guttman’s quadratic split algorithm having following features: Buffering with dirty write, Index joins, Tree Seeding, Window and NN queries, Runtime STR Packing capability, Completely Thread safe.

Mseg is a generic region-based multi-scale image segmentation algorithm designed with some optimizations for remote sensing imagery. The algorithm can be used as a low level processing part of an object-oriented image analysis system.

Military Survelliance open source GPS with Filters(like night vision,Sharpening location,Contrast) with optimal route finding algorithm embedded in the application developed in java.

This library is an implementation of the Anisotropic Morphological Leveling algorithm for Remote Sensing Imagery using the OpenCV library.
