GeoTools学习笔记

To use Referencing you need gt-opengis , gt-referencing and gt-metadata

To use Data you need gt-main , jts , gt-opengis , gt-referencing , gt-opengis , gt-metadata

The maven tool can calculate the jars you need, please see the Eclipse or Netbeans quickstart for an example use.

Usually at least one plug-in is needed for each layer for GeoTools to do something. As an example every time you use the referencing module please make sure you have an EPSG plugin around (or the referencing module will not know that “EPSG:4326” is the world as we know it).

GeoTools Extensions

We have gone a bit further and implemented some interesting “extensions” on top of the GeoTools library. These extensions provide additional capabilities that are built on top of GeoTools using the spatial facilities of the library.

The extensions are independent of each other offering and may be of use in your application. Here is a brief listing of the extensions at the time of writing.

These facilities are used by the XSD parser by way of a series of XSD plugins. These plugins indicating how to parse and encode additional content using Eclipse XSD library to parse XML schema documents and offer “bindings” showing how to parse and encode to Java classes such as String, Date, URL and Geometry.
