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.opensciencemap:vtm:'
	}
	dependencies {
		implementation("com.github.opensciencemap:vtm:")
	}
	<dependency>
	    <groupId>com.github.opensciencemap</groupId>
	    <artifactId>vtm</artifactId>
	    <version></version>
	</dependency>

                            
    libraryDependencies += "com.github.opensciencemap" % "vtm" % ""
        
        

                            
    :dependencies [[com.github.opensciencemap/vtm ""]]

Readme

Vā„¢

<br/>

Development continues at https://github.com/mapsforge/vtm #<br/> VTM is developed within the OpenScienceMap project.

Features

  • Java map library
  • OpenGL vector-tile rendering
  • Themeable vector layers
  • Support for multiple tile sources:
    • primary opensciencemap (.vtm)
    • mapsforge files
    • GeoJSON tiles
    • bitmap: any quadtree-scheme tiles as texture
  • Backends:
    • Android
    • Desktop (using libgdx/LwjGL)
    • HTML5/WebGL (using libgdx/GWT)
    • iOS (using libgdx/robovm)

Projects

  • vtm contains the core library
  • vtm-android Android backend (no libgdx required)
  • vtm-android-example provides examples using vtm-android
  • vtm-gdx common libgdx backend code
  • vtm-android-gdx Android application
  • vtm-desktop Desktop application
  • vtm-web HTML5/GWT backend
  • vtm-web-app HTML5/GWT application
  • vtm-ios iOS application

The libgdx backends for GWT and iOS are very experimental.

Getting started

git clone --recursive https://github.com/opensciencemap/vtm

Install Android SDK and build-tools 20.0. From extras add 'Android Support Library/Repository' and 'Google Repository'. The commands below should set things up correctly when Android SDK is already installed.

export ANDROID_HOME=/path/to/your/android-sdk
./android-stuff.sh

Eclipse

./gradlew eclipse<br/> Import all 'vtm' sub-projects into Eclipse.

Android-Studio

Just import build.gradle

Gradle

You can run gradle tasks directly (see also ./gradlew -q tasks):<br/> ./gradlew clean install <br/> to build the libraries and add them to the local maven repository.<br/> ./gradlew :vtm-android-example:run <br/> to run the android example<br/> ./gradlew :vtm-desktop:run <br/>to run the desktop demo (only Linux64 and Win64 native libs are provided atm)<br/> ./gradlew :vtm-web-app:jettyDraftWar <br/>to run the webgl demo<br/>
