Use === GeoTools provides an excellent series of tutorials to help you get started: * `Quickstart ` Adding GeoTools to your Application ----------------------------------- Maven (recommended): The quickstart is writen with the maven build system in mind. The maven build system is very good at sorting out dependencies between lots of little jars - and is the recommended way to start using GeoTools. Both Eclipse and NetBeans offer maven integration, for details please review the Eclipse Quickstart and NetBeans quickstart. Using maven in concert with your IDE, and looking over the pictures on this page is recommended. Download: Traditionally users just dump all the jars into their IDE and have a go, please be advised that some of the jars will be in conflict. 1. Dump everything from a binary distribution of GeoTools into your IDE 2. Remove all the jars that say epsg in them - except for the gt2-epsg jar. 3. Ensure your JRE has JAI and ImageIO if you are doing raster work 4. Ignore the rest of this page For detailed step-by-step instructions review the Eclipse quickstart and Netbeans quickstart. Instructions for downloading and selecting jars are provided at the end of the document as an alternative. Module Matrix ------------- The GeoTools library is live and online! So you can check up on modules, plugins and extensions you are about to use: * http://docs.codehaus.org/display/GEOTOOLS/Module+Matrix This page includes a description of how good each module is (more stars is better).
