GeoServer

2008年3月11日 (二) 03:26的版本

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

Coverage Plugins

GeoServer 1.6.0 支持的Coverage

• ImageMosaic / 1.0 Image mosaicking plugin
• ArcGrid / 1.0 Arc Grid Coverage Format
• Gtopo30 / 1.0 Gtopo30 Coverage Format
• GeoTIFF / 1.1 Tagged Image File Format with Geographic information
• WorldImage / 1.0 A raster file accompanied by a spatial data file

File Type

如:

• cities.avl
• cities.dbf
• cities.fix
• cities.prj
• cities.qix
• cities.shp
• cities.shx

一些格式和源数据定义:

• http://www.esri.com/metadata

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.

GeoServer Architecture

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

DataStore

geoserver支持的数据源有：PostGIS、Shapefile、ArcSDE、Oracle、VPF、MySQL、MapInfo

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.

http://docs.codehaus.org/display/GEOSDOC/MySQL+DataStore

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');

more detail: http://docs.codehaus.org/display/GEOSDOC/PostGIS+DataStore

MapInfo

There's a new MIFDataStore available that let's you read and write in Mapinfo MIF/MID format.To get more information about it see, 将mif-2.2.x.jar拷贝到如下地址:

/glassfish-v2/domains/domain1/applications/j2ee-modules/geoserver/WEB-INF/lib 重启服务器
http://localhost:8080/geoserver/config/data/store.do

and click on the "New" link, you should see the MIFDataStore in the combo box of available DataStores.
