JTS User Guide

Project Structure

JTS consists of several Java modules. Each one corresponds to a separate JAR file.

The core modules are:

• jts-core - The JTS core: geometry model, operations, algorithms, and spatial data structures
• jts-io-common - I/O classes for open spatial formats

The following modules depend on proprietary libraries, and are not built by default:

• jts-io-ora - Oracle reader and writer
• jts-io-sde - SDE reader and writer

The following modules are applications and data for testing and working with JTS

• jts-tests - The JTS XML test suite and the Test Runner application
• jts-app -The TestBuilder GUI, for working with JTS geometry interactively

Using JTS with Maven

To include JTS in a Maven project, add a dependency block like the following:

<dependency>
    <groupId>org.locationtech.jts</groupId>
    <artifactId>jts-core</artifactId>
    <version>${jts.version}</version>
</dependency>

JTS snapshot artifacts are published to the LocationTech Maven repository. To include JTS in a project, add the following repositories to the pom.

<repositories>
  <repository>
    <id>locationtech-releases</id>
    <url>https://repo.locationtech.org/content/groups/releases</url>
    <snapshots>
      <enabled>false</enabled>
    </snapshots>
  </repository>
  <repository>
    <id>jts-snapshots</id>
    <url>https://repo.locationtech.org/content/repositories/jts-snapshots</url>
    <releases>
      <enabled>false</enabled>
    </releases>
    <snapshots>
      <enabled>true</enabled>
    </snapshots>
   </repository>
