GeoTools

GeoTools jest otwart? (LGPL) bibliotek? Java, kt?ra dostarcza zgodnych ze sandardami metod do przetwarzania danych geoprzestrzennych. U?ywa ona struktur danych opartych o specyfikacje Open Geospatial Consortium (OGC).

GeoTools znajduje zastosowanie w wielu projektach, w??czaj?c us?ugi sieciowe, narz?dzia wiersza polece? i aplikacje desktopowe. Aplikacje OSGeo-Live, kt?re u?ywaj? GeoTools, to: 52°North SOS, 52°North WPS, AtlasStyler, Geomajas, Geopublisher, GeoServer, and User-friendly Desktop Internet GIS (uDig).

G??wne funkcje

• Definition of interfaces for key spatial concepts and data structures

  • Integrated Geometry support provided by JTS Topology Suite (JTS)
  • 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.
  
  • 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.

Obs?ugiwane 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

Support of numerous Open Geospatial Consortium (OGC) standards:

• OGC Style Layer Descriptor / Symbology Encoding data structures and rendering engine

• OGC Filter and Common Constraint Language (CQL)
• Clients for Web Feature Service (WFS), Web Map Service (WMS) and experimental support for Web Process Service (WPS)
• ISO 19107 Geometry
