If you are not sure how to download and get started with GRASS using its graphical user interface or using Python, checkout the tutorials [Get started with GRASS GUI](../get_started/fast_track.qmd) and [Get started with GRASS & Python in Jupyter Notebooks](../get_started/fast_track_grass_and_python.qmd).

To create a raster surface from LiDAR point cloud data, GRASS must be compiled with the [PDAL libraries](https://pdal.io/en/stable/). This capability is currently only available on Linux and OSX platforms and will be available on Windows when GRASS switches to the cmake-based build system (in development). In the meantime, the mean ground raster surface needed for the hydroflattening portion of the tutorial can be created on Windows using the [QGIS point cloud tools](https://docs.qgis.org/3.40/en/docs/user_manual/processing_algs/qgis/pointcloudconversion.html) (selecting classes 2,10,13 and setting the output resolution to 3.2808 ft).
