GeoServer项目基于J2EE平台,实现OpenGIS联合会的WFS(Web Feature Server)和WCS(Web Coverage Server)标准,并提供集成的WMS(Web Map Server)。

  • WFS(Web Feature Server) 网络: Communicates real geographic data (roads, rivers etc.) to and from the user in the form og GML(Geography Markup Language).
  • WCS(Web Coverage Server) 网络覆盖服务:
  • WMS(Web Map Server) 网络地图服务: Displays geographic data as raster(栅格) images (maps).如 Google Map
GeoServer Architecture

目录

Features

  • Fully compliant to WMS, WFS (1.0 and 1.1) and WCS specifications, as tested by the CITE conformance tests.
  • Easy to use web-based configuration tool - no need to touch long, complicated config files.
  • Mature support for PostGIS, Shapefile, ArcSDE, DB2 and Oracle.
  • VPF, MySQL, MapInfo, and Cascading WFS are also supported formats.
  • On the fly reprojection, with an embedded EPSG database supporting hundreds of projections by default.
  • Web Map output as jpeg, gif, png, SVG, GeoJSON GeoRSS.
  • Excellent Google Earth Support
  • Raw vector data available as GML and zipped Shapefiles through the WFS.
  • WCS and WMS Raster support, including support for
  • Anti-aliased images.
  • Integrated OpenLayers as a default ajax viewer.
  • Standards compliant 'by default' - no need to figure out complex configuration options just to serve basic data.
  • Streaming data readers: no memory bound limit to the amount of data that can be returned.
  • Full SLD support, both user defined (POST and GET), as well as used in styling configuration.
  • Full Filter support on all data formats in WFS (but optimized for backend format where possible).
  • Support for atomic database transactions through the standard WFS-T protocol, available on all data formats.
  • Long Transactions through a full implementation of the Locking portion of the WFS specification.
  • Innovative Validation Engine that checks inserted features against a configured set of topological and attributed based rules, to maintain backend integrity.
  • Java (J2EE) servlet-based, can run in any servlet container.
  • Designed for extension, source code that's a pleasure to read.
  • Easy to write new data formats with GeoTools DataStore interfaces and helper classes, making GeoServer the standards based interface to legacy data.
  • No need to recompile to support more data formats, GeoTools DataStores instantly plug-in to GeoServer, even showing up as an option in the configuration gui.
  • True open source development style, built by a strong community, that you can join and become a part of, tailoring GeoServer for your needs.
  • Documentation that details everything in easy to understand language.
  • Active email lists for quick support.
  • Commercial grade installation, support, customization and improvements available from an eco-system of companies, non-profits, and consulting individuals.

Install

获得 geoserver-1.6.0-RC2.exe, 包含 Jetty Web Server
安装后启动服务
服务端: http://localhost:8080/geoserver
用户名是 'admin',密码是'geoserver'
客户端: http://localhost:8080/geoserver/mapPreview.do

Maven

svn checkout https://svn.codehaus.org/geoserver/trunk/geoserver geoserver
cd geoserver
mvn compile
mvn install
cd ..
mkdir configuration
cd configuration
svn checkout https://svn.codehaus.org/geoserver/trunk/configuration/release
mvn install -DconfigId=release -DconfigDirectory=../../configuration
mvn jetty:run
http://localhost:8080/geoserver/welcome.do
or
mvn -o jetty:run // Offline Mode
or 
mvn install // Alternate data_dir configuration
mvn run -DGEOSERVER_DATA_DIR=/Users/cholmes/gs-dir

Database

MySQL

MySQL DataStore Extensions

如: http://prdownloads.sourceforge.net/geoserver/geoserver-1.4.1-mysql-plugin.zip?download
  • 1. Copy included gt2-mysql and mysql-connector-java jars included to your GeoServer library directory. In a binary install this is at [GEOSERVER_HOME]/server/geoserver/WEB-INF/lib/ In a war install this is [container]/webapps/geoserver/WEB-INF/lib/
  • 2. Restart GeoServer.

MySQL should now show up as an option in the web admin tool at Config -> Data -> Stores -> New. Fill out the appropriate params.

from http://sourceforge.net/projects/opengeodb/

CREATE DATABASE opengeodb DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT ALL PRIVILEGES ON opengeodb.* TO opengeodb@localhost IDENTIFIED BY 'opengeodb';
flush privileges;
use opengeodb;
\. opengeodb-02513_2007-10-02.sql // 45.5 MB的数据,要导入比较长的时间
或使用 mysql opengeodb < opengeodb-02513_2007-10-02.sql -uroot -p // 不知是否要快些

PostGIS

PostGIS View as a FeatureType

Create the view, which must contain the oid field from the source table:

CREATE OR REPLACE  VIEW test AS SELECT oid, key, country, geom FROM countries;

insert a record into the geometry_columns table:

INSERT INTO "geometry_columns" VALUES (,'public','test','geom',2,4326,'MULTIPOLYGON');
