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 .
Versions 2.0.0, 2.0.1 and 2.0.2 are subtly different, and different vendors implement them with variations. [5] Typically a CSW server will accept requests in one CSW version only, and it is up to the client to be flexible. e.g. ESRI Geoportal can be configured to harvest documents from CSW servers of a variety of versions and vendor variants [6] such as "GeoNetwork CSW 2.0.2 APISO".
For example, from a 7-band Landsat satellite image a range subsetting request may extract the near-infrared, red, and green range components ("bands", "channels"). The geospatial extent is unchanged, that is: "pixels" from all the coverage's locations get delivered.

The OGC membership defined and maintains the WFS specification. Numerous commercial and open-source implementations of the WFS interface standard exist, including the open-source reference implementations GeoServer and deegree. The OGC Implementing Products page [2] provides a comprehensive list of WFS implementations.
GeoJSON [1] is an open standard format designed for representing simple geographical features, along with their non-spatial attributes.It is based on the JSON format.. The features include points (therefore addresses and locations), line strings (therefore streets, highways and boundaries), polygons (countries, provinces, tracts of land), and multi-part collections of these types.
GeoServer – Written in Java and relies on GeoTools. Allows users to share and edit geospatial data. MapGuide Open Source – Runs on Linux or Windows, supports Apache and IIS web servers, and has APIs (PHP, .NET, Java, and JavaScript) for application development. Mapnik – C++/Python library for rendering - used by OpenStreetMap.
MapServer is an open-source development environment for building spatially enabled internet applications, built in the C language, and is widely known as one of the fastest Web mapping engines available.
