Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.mmeany:proj4j:0.1.0'
	}
	dependencies {
		implementation("com.github.mmeany:proj4j:0.1.0")
	}
	<dependency>
	    <groupId>com.github.mmeany</groupId>
	    <artifactId>proj4j</artifactId>
	    <version>0.1.0</version>
	</dependency>

                            
    libraryDependencies += "com.github.mmeany" % "proj4j" % "0.1.0"
        
        

                            
    :dependencies [[com.github.mmeany/proj4j "0.1.0"]]

Readme

Why I forked this ...

Proj4J does not appear to be in Maven Central. I wanted it to be accessible from Maven without having to go through hoops.

Now it can be using JitPack and using the following repository and dependency to your POM:

<repositories>
	<repository>
		<id>jitpack.io</id>
		<url>https://jitpack.io</url>
	</repository>
</repositories>

<dependency>
	<groupId>com.github.mmeany</groupId>
	<artifactId>proj4j</artifactId>
	<version>0.1.0</version>
</dependency>

Welcome to Proj4J

Proj4J is a Java library to transform point coordinates from one geographic coordinate system to another, including datum transformations.

The core of this library is a port of the PROJ.4 C library. The projection algorithms, concepts and coordinate system definitions are all taken directly from PROJ.4. These are wrapped in a Java class model which follows standard Java conventions and OO best practices.

Proj4J is a part of the MetaCRS group of projects, hosted by OSGeo.

Documentation

  • The PROJ.4 documentation is the best reference for details of the coordinate system specification language, projection algorithms and supported parameters.

  • the [Version History](doc/Proj4J Version History.html) lists the evolution of features of the library

  • the Javadoc describes the API

Mailing List

A mailing list is available for users and developers of Proj4J.

History

The Proj4J codebase is based on a partial port of PROJ.4 carried out by JHLabs circa 2006. The JHLabs port provided a large number of the PROJ.4 projections, but did not support some PROJ.4 features such as datum transformation.
