GeoTools is popular Java library used by web services, cloud solutions, command line tools and desktop applications.

Core features

  • Definition of interfaces for key spatial concepts and data structures

    • Integrated Geometry support provided by Java 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
    • Vendor extensions for fine control of text labels and color blending
  • 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

    • rovide additional capabilities built using the spatial facilities 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.
    • Highlights include swing support (used in our tutorials!), swt, local and web process support, additional symbology, additional data formats, generation of grids and a couple of implementations of ISO Geometry.
  • Supported Formats

    • Raster formats and data access including arcsde, arcgrid, geotiff, grassraster, gtopo30, image (JPEG, TIFF, GIF, PNG), imageio-ext-gdal, imagemosaic, imagepyramid, JP2K, matlab
    • Database support for db2, h2, mysql, oracle, postgis, spatialite, sqlserver
    • Vector formats and data access including arcsde, csv, dxf, edigeo, excel, geojson, org, property, shapefile, a wfs client
    • Advanced vector formats including application schema support allowing mapping of information to a predefined data product.
    • XML Bindings for 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.

Implemented Standards

  • Geographic JSON (GeoJSON)
  • Georeferenced Tagged Image File Format (GeoTIFF)
  • Geography Markup Language (GML)
  • Keyhole Markup Language (KML)
  • Styled Layer Descriptor (SLD)
  • Web Coverage Service (WCS)
  • Web Feature Service (WFS)
  • Web Feature Service - Transactional (WFS-T)
  • Web Map Service (WMS)
  • Web Map Tile Service (WMTS)
  • Web Processing Service (WPS)
