GeoTools is an open source java GIS toolkit.

GeoTools is an open source (LGPL) Java code library which provides standards compliant methods for the manipulation of geospatial data, for example to implement Geographic Information Systems (GIS). The GeoTools library implements Open Geospatial Consortium (OGC) specifications as they are developed, in close collaboration with the GeoAPI and GeoWidgets projects. Includes two great SLD based renderers, raster access and reprojection. Plugns fo Shapefile, ArcGrid, ArcSDE, Postgis, OracleSpatial, MySQL and many more.

Using NetBeans with Geotools

GeoTools2 is developed using the same modular structure as Netbeans and we plan to integrate GeoTools into Netbeans.

uDig is also GeoTools application.

There are two system architecture patterns in use:

• layers for data abstraction
• plugins for extendability

[编辑] Getting Started

[编辑] Database

[编辑] PostGIS

JDBC DataStore

map = new HashMap();
map.put("dataSource", source);
map.put("dbType", "postgis");
DataStore store = DataStoreFinder.getDataStore(map);

connect PostGIS

java.util.Map params = new java.util.HashMap();
params.put(PostgisDataStoreFactory.DBTYPE.key, "postgis");
params.put(PostgisDataStoreFactory.HOST.key, "localhost");
params.put(PostgisDataStoreFactory.PORT.key, 5432);
params.put(PostgisDataStoreFactory.SCHEMA.key, "public");
params.put(PostgisDataStoreFactory.DATABASE.key, "database");
params.put(PostgisDataStoreFactory.USER.key, "postgres");
params.put(PostgisDataStoreFactory.PASSWD.key, "postgres");
DataStore dataStore=DataStoreFinder.getDataStore(params);
String typeName = dataStore.getTypeNames()[0];
FeatureSource featureSource = dataStore.getFeatureSource( typeName );
