扩展
除此之外,GeoTools
团队在GeoTools
的基础上实现了一些扩展,当然了,这些扩展是为了提供一些额外的功能。这些扩展是相互独立的,我们可以直接在项目中使用。
JAR | Extension |
---|---|
gt-graph | Work with graph and network traversals |
gt-validation | Quality assurance for spatial data |
gt-wms | Web Map Server client |
gt-xsd | Parsing/Encoding for common OGC schemas |
gt-brewer | Generation of styles using color brewer |
GeoTools
团队为了支持GeoTools
中的XML模块,将几个XML模式打包成JAR形式,方便开发者进行调用。
JAR | Schema |
---|---|
net.opengis.ows | open web services schema |
net.opengis.wfs | web feature service |
net.opengis.wps | web processing service schema |
net.opengis.wcs | web coverage service schema |
net.opengis.wfs | web feature service schema |
org.w3.xlink | XLink schema |
XSD解析器通过一系列XSD插件使用这些工具。这些插件指示如何使用Eclipse XSD库解析和编码额外的内容来解析XML模式文档,并提供“绑定”,显示如何解析和编码Java类,如String、Date、URL和Geometry。
JAR | Bindings |
---|---|
gt-xsd-core | Basic types defined by XML schema |
gt-xsd-fes | filter 2.0 |
gt-xsd-filter | filter (used by OGC CAT and WFS) |
gt-xsd-kml | keyhole markup language |
gt-xsd-wfs | web feature service |
gt-xsd-wps | web processing service |
gt-xsd-gml3 | geographic markup language 3 |
gt-xsd-gml2 | geographic markup language 2 |
gt-xsd-ows | open web services |
gt-xsd-wcs | web coverage service |
gt-xsd-wms | web map service |
gt-xsd-sld | style layer descriptor |
以下是GeoTools
不支持的扩展,你也可以使用Maven下载它们来使用。
