OverviewOverview

GeoServer is an open source server for sharing geospatial data.

Designed for interoperability, it publishes data from any major spatial data sourceusing open standards.

Server

Status: provides a summary of server configuration parameters and run-timestatus.

Contact Information:

Global Settings: configures messaging, logging, character, and proxysettings for the entire server.

Web Administration InterfaceWeb Administration Interface

Server (Cont.)

Coverage Access Settings: provides configuration options to customize threadpool executors and ImageIO caching memory.

JAI: provides reader, writer, and stream plug-ins for the standard Java Image I/OFramework, and configures JAI parameters for WMS and WCS operations

•Java Advanced Imaging (JAI) is an image manipulation library built by SunMicrosystems and distributed with an open source license.

REST (Representational State Transfer) Configuration: allows to create newstores and append new granules to mosaics via file uploads.

Web Administration InterfaceWeb Administration Interface

Layer Preview

provides layer views in various output formats.

Web Administration InterfaceWeb Administration Interface

Data

Workspaces: describes how to view and configure workspaces.

Store: connects to a data source that contains raster or vector data.

Layers: refers to raster or vector data that contains a collection of geographicfeatures.

Layer Groups: a container in which layers and other groups can be organized in ahierarchical structure.

•Single: the layer group is exposed as a single layer with a name.

•Named tree: the layer group can be referred to by one name, but also exposesits nested layers and groups in the capabilities document.

•Container tree: the layer group is exposed in the capabilities document, but doesnot have a name, making it impossible to render it on its own.

•Earth Observation tree: a special type of group created to manage the WMSEarth Observation requirements.

Tile Caching

Tile Layers: shows a listing of all of the layers known to the integratedGeoWebCache. It is similar to the Layer Preview for GeoWebCache, with manyof the same options.

Demo page: enables viewing configured layers, reloading the configuration, andseeding or refreshing the existing cache on a per-layer basis.

Caching defaults: shows the global configuration options for the tile cachingfunctionality in GeoServer, an embedded GeoWebCache.

Gridsets: defines a spatial reference system, bounding box (extent), a list of zoomlevels (resolutions or scale denominators), and tile dimensions.

Disk Quotas: manages the disk usage for cached tiles and allows you to set theglobal disk quota.

Web Administration InterfaceWeb Administration Interface

Security

Settings: controls the global GeoServer security settings.

Authentication: manages the authentication options, including authenticationproviders and the authentication chain.

Passwords: configures the various options related to Passwords, the Masterpassword, and Password policies.

Users, Groups, Roles: provides the configuration options for User/group servicesand Role services.

Data: provides access to security settings related to data management and Layersecurity.

Web Administration InterfaceWeb Administration Interface

Security

Services: provides access to the settings for Service Security.

File Browsing: exposes locations of the file system other than the GeoServerdirectory.

Web Administration InterfaceWeb Administration Interface

Demos

Demo Requests: provides example WMS, WCS and WFS requests for GeoServerthat you can use, examine, and change.

SRS (Spatial Referencing Systems): supports almost 4,000 SRS, also known asprojections, and more can be added.

WorldImage

a plain text file used to georeference raster map images. This file (often with anextension of .jgw or .tfw) accompanies an associated image file (.jpg or .tif).Together, the world file and the corresponding image file is known as aWorldImage in GeoServer.
