GeoServer

2008年2月29日 (五) 04:29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

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');

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

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.
