Quick Start Guide

Overview

  • Download and install JSAGA.
  • As a start, you can try the command line interfaces provided with JSAGA (see examples below). Please note that these commands are intended to check your configuration and are provided as examples only. We do not recommend to use them in production.
  • If you install and use several adaptors, default configurations may overlap and you will have to configure adaptors (see configuration examples of plug-ins).
  • Use the SAGA API in your Java code (see code examples).
