Fahim Imaduddin Dalvi f46f25dbaf Updated Dockerfile for more efficient builds. 
We now use multi-stage builds so that the build-time dependencies and
code are not included in the final image. Also updated the README with
information about Docker hub, and added a LICENSE file.

VirtualPlanetBuilder Terrain Generation for FlightGear

This repository provides a DockerFile that can generate an image to build VPB terrain. It is currently based on the following versions:

  • Ubuntu 20.04 (LTS)
  • GDAL 2.4
  • OpenSceneGraph 3.6.5
  • VirtualPlanetBuilder 1.0

The image is available on Docker Hub, so docker will download it automatically when it is requested for the first time.

Building terrain

The provided run_image.sh will launch a container and present a bash prompt with the environment for building all set up:

  • GDAL and VPB executables will be available to run
  • The data directory will be mounted at /home/flightgear/data/ inside the container (readonly)
  • The output directory will be mounted at /home/flightgear/output inside the container with write access

A sample script in data/run.sh is provided to automatically build a small area around Edinburgh. To build the terrain:

  1. First download SRTM heightmap and CORINE landclass data (see the wiki for details: https://wiki.flightgear.org/Virtual_Planet_Builder and data/run.sh for links)
  2. Extract the files to ./data
  3. Launch the container with ./run_image.sh
  4. Run ./data/run.sh at the prompt. The script will saves all output to the mounted ./output folder, so its accessible outside the container.

A shorthand for steps 3-4 is also available:

./run_image.sh ./data/run.sh

Building Image locally

To build the image locally for debugging or contributing, run build_image.sh. This will build and tag the image with the name flightgear/ws30-vbp-generator:v1.
