JTS Topology Suite

Fork of original project from: svn://svn.code.sf.net/p/jts-topo-suite/code

Welcome to the repository for the JTS Topology Suite. JTS essentially consists of several Java modules, each one corresponding to a separate JAR file. Only jts-core is necessary to use the library in an application. The others are external tools or optional extensions. To read more about specific modules check pom.xml description.

Project site

Develope JTS

Java IDEs support Maven projects out of the box. Just import them, the rest should be automatically configured. Some jts-io-* projects require additional jars which are not easily obtainable. Check poms for more information.

Build JTS

The JTS library is intended to be Java 1.6 compatible (to permit deployment on Android 2.3+). The tools are not subject to this limitation, so you can target higher Java versions.

• In the root directory execute

  mvn install

Test JTS

• Java unit tests can be executed using

  mvn test

• XML tests run during integration-test phase of jts-test-library project:

  mvn integration-test

• Some XML tests are executed separately since they should fail. Until test runner doesn't support such case use:

  mvn exec:exec

Deploy JTS

JTS snapshot build will be deployed to GitHub pages based, Maven repository.

Maven Snapshots

Maven Releases

*Currently coverage is calculated only for jts-core (which is most relevant)

jts's Issues

Improve jts-webapp

-rename to jts-webapp (from *-gwt-example)
-provide favicon

license maven plugin

could be used to keep license in java files up to date

Maybe support other proprietary formats like MS geometry binary format

• ms support is already available in hibernate spatial.

jts-core has dependency on a snapshot version not publicly available.

The jrs-core pom file uses a snapshot version (5.3.4-SNAPSHOT) of the com.igormaznitsa:jcp plugin. Since 5.3.4 has now been released presumably the final version can now be used? At least I was able to successfully build after modifying the pom...

Execute preprocessed junit tests from Core on JTS GWT

Currently this is problematic because usage of some JVM specific classes is replaced with GWT counterparts. Because of that some tests have runtime errors (GWT.create() used behind the scenes).

copy() methods should have assertions that they are called from their own class

First line of every copy():
assert getClass() == < LiteralOfImplementingClass >.class

Mainly to limit cases where copy is used and only partial copy would be provided. This is not needed in case of clone() because it makes shallow copy automatically.

Something else than assert is also feasible.

Thread-safety support

Hi,
Is this library thread safe?

I have a MULTILINESTRING and I am trying to find its intersection with other LineString. As the number of LineString is hugh, I am thinking of processing it parallelly.
Can I use this lib in multiprocessing environment?

Remove excessive logging in unit tests

Use logging library instead of System.out so it's possible to limit log output (instead of totally redirecting it to files).

Support jdk14 using retro tool.

http://retrotranslator.sourceforge.net/
http://retroweaver.sourceforge.net/
http://jbossretro.jboss.org/

So there would be 3 editions of jts:
jts-< version >
jts-< version >-jdk14
jts-< version >-gwt

Update performance tests so it's possible to detect degradation after making changes.

Add thresholds which will warn about minor degradation, fail the build in case of major performance issues?

Create xml, GWT compatible test runner and execute it in the browser

Update scripts for running TestBuilder and TestRunner

They are in jts-test-library/src/main/scripts.

Run test coverage tool to detect untested pieces of code

Sonar? Maybe coveralls.

Create maven project site and publish it on GitHub pages

Include subpages which will replace pdfs in jts/src/site.
Useful: https://help.github.com/categories/20/articles

Do scheduled builds and deploy SNAPSHOT to GitHub pages

Useful info: http://blog2.vorburger.ch/2013/08/deploying-github-hosted-maven-incl.html

Split TestBuilder and TestRunner into separate projects

They may share common things (in form of 3rd project)

Run xml tests on Travis using TestRunner

Using test runner app in jts-app. It may require modifications since Travis doesn't support GUI apps.
