The development community in building GIS solutions is sustaining an enormous level of effort. The GeoAPI project aims to reduce duplication and increase interoperability by providing neutral, interface-only APIs derived from OGC/ISO Standards.

Siafu simulates individual agents and their context, from home to city-wide scenarios. As a developer, you use the API to write your simulation for the purposes of data-set generation, test or visualization, optionally hooking it to your own application.

GPSylon is a Java moving map application that is able to display maps like in an atlas and show your position by the use of a gps device. It may track your path, load overlays (e.g. shape files), download maps from expedia servers. - The source code was moved to github!

Tool for testing Web Map Services. It allows to run general random tests of WMS and test based on user-like behaviour.

BizGEO is an open source platform developed to provide a simple interface for geographical data collection and data storage. BizGEO is integrated with a standard open source map server (GeoServer) to form an integrated GIS data collection suite. BizGEO is made up of three main components; BizGEOServer which is a facility for managing data by organising them in projects; BizGEOApp, a mobile app which is being used by the field users to collect data through set of defined forms, and GeoServer which manages and publishes the data using open standards.

This SourceForge.net project serves as repository and distribution point for Carbon Five Open Source software and documentation.

Generic Mobility Simulation Framework (GMSF)

NOTE: this project has been renamed as GeoGig. Use this URL to get to the GeoGig downloads: https://sourceforge.net/p/geogig Welcome to the GeoGit project, exploring the use of distributed management of spatial data. GeoGit draws inspiration from Git, but adapts its core concepts to handle versioning of geospatial data. Users are able to import raw geospatial data (currently from Shapefiles, PostGIS or SpatiaLite) in to a repository where every change to the data is tracked. These changes can be viewed in a history, reverted to older versions, branched in to sandboxed areas, merged back in, and pushed to remote repositories.

Geoclipse is a collection of Eclipse plugins, that allow you to add mapping capabilities to your Eclipse Rich Client applications. Current development happens on github! http://michaelkanis.github.com/geoclipse

Geomajas is a web mapping GIS software with full vectorial editing capabilities, and support for custom attribute relation models in the browser. It has built-in support for any type of query, selection, filtering, snapping, printing, ...

Integrate the power of the fully AJAX enabled technology of ICEfaces into the framework of the ESRI WebADF. No need to code in Javascript or to handle XML communication to build AJAX functionalities. OnlineDemo: http://www2.pch.etat.lu/pchViewer

JOSAST ( Java Open Source Amateur Satellite Toolkit) is a set of java source code used for amateur satellite, hamradio and also astronomia activities ... Reusable package and complete software should be available.

Java Marine API is an NMEA 0183 library for Java. For furher info and latest source code, see project's Github pages. https://github.com/ktuukkan/marine-api/

KalypsoBASE is a Desktop-GIS built on Eclipse. It's focus lies on modelling gis data using GML Application-Schemata. Features contain generic dialogs based on GML, maps based on OGC's SLD, and other tools like a charting framework or API for timeseries

KartoMNT is a free software of height model digitalization. This software allows you to create your own Digital Height Models (DHM) with a simple map. Then you'll be able to visualize DHMs with the KartoMNT 3D viewer.

LGML is a GML parser under the LGPL license. The aim is to parse a GML document or fragment in order to get a WKT output. 2D and 3D inputs are both handled, but it is not permitted to have mixed geometries. The caller can choose if the input coordinates are parsed as X, Y, Z (if present) order, or Y, X, Z (if present) order. The willing of the project is to be a starting point useful for developers that need to parse GML objects in order to use them, for example, in the context of OGC catalogue projects. The library is compiled using Java 1.5 or 1.6. For now, supported inputs are: LineString, MultiLineString, MultiPoint, MultiPolygon, Point, Polygon, MultiSurface (in an experimental way: the only child object handled is Polygon). At the following URL: http://95.110.227.201:8080/lgml is exposed a minimal web interface in order to test it.

An attempt to design minimum cost broadband networks with the use of a modified version of the Particle Swarm Optimization method. A GIS subsystem is used for the visualization of data and results.

Nomin is a mapping engine for the Java platform. It provides abilities to transform object trees using declarative mapping rules. Main features are no XML configuration, intuitively looking mapping, using arbitrary expressions/method invocations.

OSIOSS (Open Source Integrated Observing System Software) is a collection of code which can be used for geospatial observing systems merging data collection, management and products solutions with ocean observing systems (OOS) as an initial focus.

A very simple command line tool to convert OSM files to Shapefiles. Written in Java. Think of it as a self-study project.

Plus Codes are like street addresses for people or places that don’t have one. Instead of addresses with street names and numbers, Plus Codes are based on latitude and longitude and displayed as numbers and letters. With a Plus Code, people can receive deliveries, access emergency and social services, or just help other people find them. Plus Codes technology is open source and free to create and use. They are much shorter than traditional global coordinates, so they’re easy to share. Plus Codes work whether you’re online or offline, you don’t need an internet connection. Plus Codes are based on a set of 20 alphanumeric characters. They do not include easily confused characters, are not case-sensitive, and exclude vowels. Plus Codes represent an area. The resolution of the area can be changed by adding or removing characters after the “+” sign. Simple, free to use, open-source digital addressing, for the entire world.
