Thank you for downloading GeoTools 21.2. This release was created on June 27 2019.
This release contains only a subset of the current GeoTools code base. The full GeoTools code base contains additional unsupported modules covering experiments with a range of additional data formats. Only the modules which are considered to be stable have been included in this release.
For more information, and documentation on the GeoTools library please see the GeoTools User Guide.
The user guide includes the following tutorials:
Quickstart (Eclipse , Netbeans or Maven)
Geometry CRS Tutorial
Map Style Tutorial
- Additional tutorials cover topics such as making your own function, process or datastore.
Welcome to GeoTools development!
The following is provided as a quick reference only, please the GeoTools User Guide.
To use the GeoTools libraries you will need:
- Java 11: OpenJDK distribution tested
- Java 8: Oracle JDK implementations tested
Java 8 runtime extensions Java Advanced Imaging (JAI) and the Java Image IO (JIO) will be used if installed. GeoTools will use the pure java implementation of these libraries if the native extensions are not installed.
Additional spatial formats are provided by the ImageIO-Ext project including raster formats such as MRSID and ECW. Detailed instructions on configuring your JRE with these optional extensions can be found in our developers guide here.
Oracle JDBC Integration (Optional)
In order to use the gt-oracle or gt-jdbc-oracle modules, you need the Oracle JDBC driver from Oracle. Unlike most external libraries used in GeoTools, we cannot redistribute this jar.
However, you can obtain them from the Oracle website, free of charge, after registering:
Please see the users guide for detailed instructions.
In order to build GeoTools you will need a copy of Maven project management tool from the Apache Software foundation.
With maven installed, you can perform a full build from the GeoTools folder and typing:
Please read the User Guide for more information about maven.
Getting Involved (Recommended)
The gt2-users mailing list is provided for general inquiries, with additional support options are available in the user guide.
If you are interested in the future development of GeoTools join the geotools-devel mailing list. We welcome contributions of new modules as well as keen developers who want to work on the project as a whole. For background on how the project functions see the Developers' Guide.
