GeoTools
GeoTools is a free software (LGPL) GIS toolkit for developing standards compliant solutions. It provides an implementation of Open Geospatial Consortium (OGC) specifications as they are developed. GeoTools is a contributor to the GeoAPI project - a vendor-neutral set of Java interfaces derived from OGC specifications - and implements a subset of those. It is written in Java and currently is under active development. It is used by GeoServer, uDig, Geopublisher, 52N, Geomajas and many proprietary projects. Core features GeoTools library supports the following core features: * Interfaces for spatial concepts and data structures; * JTS Topology Suite Geometry; * Attribute, Spatial and Temporal filters matching the OGC Filter specification; * Decoding technology (with bindings for manyGML, Filter, KML, SLD, and SE and other OGC standards). The GeoTools library forms a stack for the core modules; with additional plugins available to support additional formats, extensions and i ...

GeoServer
In computing, GeoServer is an open-source server written in Java that allows users to share, process and edit geospatial data. Designed for interoperability, it publishes data from any major spatial data source using open standards. GeoServer has evolved to become an easy method of connecting existing information to virtual globes such as Google Earth and NASA World Wind as well as to web-based maps such as OpenLayers, Leaflet, Google Maps and Bing Maps. GeoServer functions as the reference implementation of the Open Geospatial Consortium Web Feature Service standard, and also implements the Web Map Service, Web Coverage Service and Web Processing Service specifications. Goals GeoServer aims to operate as a node within a free and open Spatial Data Infrastructure. Just as the Apache HTTP Server has offered a free and open web server to publish HTML, GeoServer aims to do the same for geospatial data. Features GeoServer reads a variety of data formats, including: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Open Source Geospatial Foundation
The Open Source Geospatial Foundation (OSGeo), is a non-profit non-governmental organization whose mission is to support and promote the collaborative development of open geospatial technologies and data. The foundation was formed in February 2006 to provide financial, organizational and legal support to the broader Free and open-source geospatial community. It also serves as an independent legal entity to which community members can contribute code, funding and other resources. OSGeo draws governance inspiration from several aspects of the Apache Foundation, including a membership composed of individuals drawn from foundation projects who are selected for membership status based on their active contribution to foundation projects and governance. The foundation pursues goals beyond software development, such as promoting more open access to government produced geospatial data and completely free geodata, such as that created and maintained by the OpenStreetMap project.

Open Geospatial Consortium
The Open Geospatial Consortium (OGC), an international voluntary consensus standards organization for geospatial content and location-based services, sensor web and Internet of Things, GIS data processing and data sharing. It originated in 1994 and involves more than 500 commercial, governmental, nonprofit and research organizations in a consensus process encouraging development and implementation of open standards. History A predecessor organization, OGF, the Open GRASS Foundation, started in 1992. From 1994 to 2004 the organization also used the name Open GIS Consortium. The OGC website gives a detailed history of the OGC. Standards Most of the OGC standards depend on a generalized architecture captured in a set of documents collectively called the ''Abstract Specification'', which describes a basic data model for representing geographic features. Atop the Abstract Specification members have developed and continue to develop a growing number of specifications, or ''stan ...

JTS Topology Suite
JTS Topology Suite (Java Topology Suite) is an open-source Java software library that provides an object model for Euclidean planar linear geometry together with a set of fundamental geometric functions. JTS is primarily intended to be used as a core component of vector-based geomatics software such as geographical information systems."The 2012 Free and Open Source GIS Software Map – A Guide to facilitate Research, Development and Adoption" S. Steiniger and A.J.S. Hunter It can also be used as a general-purpose library providing s in |
Rewrite (programming)
A rewrite in computer programming is the act or result of re-implementing a large portion of existing functionality without re-use of its source code. When the rewrite is not using existing code at all, it is common to speak of a rewrite from scratch. Motivations A piece of software is typically rewritten when one or more of the following apply: *its source code is not available or is only available under an incompatible license *its code cannot be adapted to a new target platform *its existing code has become too difficult to handle and extend *the task of debugging it seems too complicated *the programmer finds it difficult to understand its source code *developers learn new techniques or wish to do a big feature overhaul which requires much change *developers learn that new codes written may extend content options that can fix or overwrite previous problems *the programming language of the source code has to be changed Risks Several software engineers, such as Joel Spolsky h ...

GeoAPI
GeoAPI is free software providing a set of Java interfaces for GIS applications. GeoAPI interfaces are derived from the abstract model and concrete specifications published collaboratively by the International Organization for Standardization ( ISO) in its 19100 series of documents and the Open Geospatial Consortium ( OGC) in its abstract and implementation specifications. GeoAPI provides an interpretation and adaptation of these standards to match the constraints and usages of the target programming language. The international standards translated to Java interfaces are: * ISO/TS 19103:2005 — Conceptual schema language * ISO 19115:2003 — Metadata * ISO 19115-2:2009 — Metadata — Part 2: Extensions for imagery and gridded data * ISO 19111:2007 — Spatial referencing by coordinates GeoAPI 3.0 has been approved as an OGC standard and is published as an OGC implementation specification. The Java Archive Files are available from the Apache Maven central repository. See also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free Software
Free software or libre software is computer software distributed under terms that allow users to run the software for any purpose as well as to study, change, and distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program.Selling Free Software (gnu.org) Computer programs are deemed "free" if they give end-users (not just the developer) ultimate control over the software and, subsequently, over their devices. The right to study and modify a computer program entails that |

LGPL
The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. The LGPL was developed as a compromise between the strong copyleft of the GNU General Public License (GPL) and more permissive licenses such as the BSD licenses and the ...

Java (programming Language)
Java is a high-level, class-based, object-oriented programming language that is designed to have as few implementation dependencies as possible. It is a general-purpose programming language intended to let programmers ''write once, run anywhere'' ( WORA), meaning that compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax of Java is similar to C and C++, but has fewer low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as reflection and runtime code modification) that are typically not available in traditional compiled languages. , Java was one of the most popular programming languages in use according to GitHub, particularly for client–server web applications, with a reported 9 million developers. Java was originally develo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
