GeoTools
================================================================================

GeoTools jest otwartą (LGPL) biblioteką Java, która dostarcza zgodnych ze sandardami metod do przetwarzania danych geoprzestrzennych. Używa ona struktur danych opartych o specyfikacje Open Geospatial Consortium (OGC).

GeoTools znajduje zastosowanie w wielu projektach, włączając usługi sieciowe, narzędzia wiersza poleceń i aplikacje desktopowe. Aplikacje OSGeo-Live, które używają GeoTools, to: 
:doc:`52nSOS_overview`, :doc:`52nWPS_overview`, :doc:`atlasstyler_overview`, :doc:`geomajas_overview`, :doc:`geopublisher_overview`, :doc:`geoserver_overview`, and :doc:`udig_overview`.

Główne funkcje
--------------------------------------------------------------------------------

* Definition of interfaces for key spatial concepts and data structures
  
  * Integrated Geometry support provided by `JTS Topology Suite (JTS) <http://tsusiatsoftware.net/jts/main.html>`_
  * Attribute and spatial filters using OGC Filter Encoding specification
  
* A clean data access API supporting feature access, transaction support and locking between threads
  
  * Access GIS data in many file formats and spatial databases
  * Coordinate reference system and transformation support
  * Work with an extensive range of map projections
  * filter and analyze data in terms of spatial and non-spatial attributes

* A stateless, low memory renderer, particularly useful in server-side environments.
  
  * compose and display maps with complex styling

* Powerful *schema assisted* parsing technology using XML Schema to bind to GML content
  
  * The parsing / encoding technology is provided with bindings for many OGC standards including GML, Filter, KML, SLD, and SE.
  
* GeoTools Plugins: open plug-in system allowing you to teach the library additional formats
  
  * Plug-ins for the ImageIO-EXT project allowing GeoTools to read additional raster formats from GDAL
 
* GeoTools Extensions

  * Provide additional capabilities built using the spatial facilites of the core library.

     :alt: Extensions built using the GeoTools library

  * Extensions provide graph and networking support (for finding the shortest path), validation, a web map server client, bindings for xml parsing and encoding and color brewer.

* GeoTools Unsupported
  
  * GeoTools also operates as part of a wider community with a staging area used to foster new talent and promote experimentation.
  
  * Some highlights are swing support (used in geotools tutorials), swt, local and web process support, additional symbology, additional data formats, generation of grids and a couple of implementations of ISO Geometry.

Obsługiwane formaty

* raster formats and data access:
  
  arcsde, arcgrid, geotiff, grassraster, gtopo30, image (JPEG, TIFF, GIF, PNG), imageio-ext-gdal, imagemoasaic, imagepyramid, JP2K, matlab.
  
* Database "jdbc-ng" support:
  
  db2, h2, mysql, oracle, postgis, spatialite, sqlserver.

* Vector formats and data access:
  
  app-schema, arcsde, csv, dxf, edigeo, excel, geojson, org, property, shapefile, wfs.

* XML Bindings:

  Java data structures and bindings provided for the following:
  xsd-core (xml simple types), fes, filter, gml2, gml3, kml, ows, sld, wcs, wfs, wms, wps, vpf.
  
  Additional Geometry, Filter and Style parser/encoders available for DOM and SAX applications.
  
Zaimplementowane standardy
