Efficiently updating constrained delaunay triangulations
DNRGPS and its predecessor were built to transfer data between Garmin handheld GPS receivers and GIS software." "This page is about the german topographic data transfer standard EDBS/ATKIS and a reader for this format.Owing to the specific nature of this data format, the following information is exclusively available in German." This project, called E-FOTO, aims to develop and manage an educational photogrammetric softcopy kit. It supports a variety of popular platforms (Windows, Mac, Linux, etc.) and is developed by skilled volunteers from around the world." [ License: GNU General Public License (GPL) ]Is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats." [ License: Free Type or GNU ]FMaps is here to answer the lack of user friendly opensource GIS/RS (Geographic Information System/ Remote Sensing) application on the Linux and Gnome compatible platforms.As a library, it presents a single abstract data model to the calling application for all supported formats." [ License: MIT] "This is the submission that won the 2002 Google Programming Contest.It includes a geocoder (which uses TIGER/Line data to turn street addresses into latitude/longitude coordinates), a simple indexer that looks for addresses and keywords in documents, and a query engine to search for documents matching certain keywords that also contain addresses within a certain distance of a target location." "is a public service providing free geocoding of addresses and intersections in the United States.City Tracking is intended to be a public, open source project that takes data about cities and lays it open for examining from many angles so it can be optimized for use by city personnel, journalists, and the public (including businesses).Along the way well release server-side code bases, mapping algorithms, managed datasets, APIs and API specs, and new views on data." Software: https://github.com/Citytracking/ "Our mission is to empower communities to collaboratively build and share geographic data using standards-based, open source tools.We develop mapbuilder-lib, an open source library of browser based mapping widgets.
Demeter is designed for fast performance and good visual quality and makes use of advanced techniques such as dynamic tessellation (adaptive mesh) to render vast landscapes in real-time, without the need for high-end hardware.The application has the following features: 1) Display a map with streets, railways, rivers, parks, altitude and other features. The route-finder can be customized to match the cyclists preferences (fastest or nicest route, keep wind direction and hills into account etc.). 4) Automatically fetch current Berlin weather data." Buddy Space "Buddy Space is an instant messenger with four novel twists: (1) it allows optional maps for geographical & office-plan visualizations in addition to standard 'buddy lists'; (2) it is built on open source Jabber, which makes it interoperable with ICQ, MSN, Yahoo and others; (3) it is implemented in Java, so it is cross-platform; (4) it is built by a UK research lab, so it is 100% free with full sources readily available.
