## Welcome to osgEarth!

osgEarth adds geospatially accurate 3D maps to your C++ application.

osgEarth builds on trusted open source technologies like OpenSceneGraph and GDAL to give you high-performance, accurate terrain and map rendering. It supports a myriad of geospatial data formats and map projections.

## Install the SDK

Windows users can install the latest version of osgEarth through `vcpkg`:
```bat
git clone https://github.com/microsoft/vcpkg.git
cd vcpkg && bootstrap-vcpkg.bat
vcpkg install osgearth:x64-windows
```
This will take a while the first time as vcpkg builds osgEarth and its dependencies.

## Check out some examples

`osgearth_imgui` is the main command-line viewer. `osgearth_viewer` is a stripped-down viewer without any GUI.
Both of these read "earth files", XML files that describe the contents of a map.

You can find example earth files in the `tests` folder of the repo.

```bat
:: Online imagery and elevation:
osgearth_imgui tests\readymap.earth

:: OpenStreetMap:
osgearth_imgui tests\osm.earth

:: Local GeoTIFFs:
osgearth_imgui tests\simple.earth 
```

## Integrate it into your project

CMakeLists.txt
```cmake
cmake_minimum_required(VERSION 3.20)
project(myApp)
find_package(osgEarth CONFIG REQUIRED)
add_executable(myApp main.cpp)
target_link_libraries(myApp PRIVATE osgEarth::osgEarth)
install(TARGETS myApp RUNTIME DESTINATION bin)
```
main.cpp
```c++
#include <osgEarth/MapNode>
#include <osgEarth/TMS>
#include <osgEarth/EarthManipulator>
#include <osg/ArgumentParser>
#include <osgViewer/Viewer>

int main(int argc, char** argv)
{
    osgEarth::initialize();
    
    osg::ArgumentParser args(&argc, argv);
    osgViewer::Viewer viewer(args);
    
    auto imagery = new osgEarth::TMSImageLayer();
    imagery->setURL("https://readymap.org/readymap/tiles/1.0.0/7/");
    
    auto mapNode = new osgEarth::MapNode();
    mapNode->getMap()->addLayer(imagery);
    
    viewer.setSceneData(mapNode);
    viewer.setCameraManipulator(new osgEarth::EarthManipulator(args));
    
    return viewer.run();
}
```
