FlightGear Download and Install Complete Scenery on Linux

FlightGear is a powerful open-source flight simulator that allows users to create their own custom scenery. However, compiling and installing the scenery can be a complex process. In this article, we will provide a step-by-step guide on how to download and install complete scenery on Linux using TerraGear.

Compiling Scenery

The first step in creating your own scenery is to compile it. This process takes longer than other methods but is more efficient overall. We recommend breaking down the process into smaller areas, such as 10x10 degrees sections, which will result in four files. To begin, select 'Temporary Places' and choose 'Elevation' and then either 5x5 degree tiles or 1x1 degree subtiles.

Using GPL Compliant Data

When using GPL compliant data for scenery creation, it's essential to download elevation data from the USGS (SRTM 3 version 2_1). However, please note that this license is not compatible with FlightGear's GPL license. As a result, any scenery created with SRTM 3 data cannot be released as official scenery.

Alternative Elevation Data

Fortunately, there is an alternative elevation dataset available from CGIAR (SRTM version 4), which is free and updated regularly. This data can be used for scenery creation, but keep in mind that it's not compatible with FlightGear's GPL license. As a result, any scenery created with SRTM 4 data cannot be released as official scenery.

Compiling Terragear

To compile Terragear, follow the instructions outlined in the 'Building terragear-cs in Ubuntu' guide. The first step after compiling Terragear is to go to the file BuildTiles/Main/main.cxx and ensure that the CPU rlimit is set to a large number. This will allow fgfs-construct to run for an extended period.

Important Notes

When creating scenery with SRTM 4 elevation data from CGIAR (for non-commercial use), it's essential to note that this data cannot be released under GPL terms and therefore cannot be included in official FlightGear releases.

Contributing to Official Scenery

If you're interested in contributing to official FlightGear scenery, please be aware that some of the data sources mentioned in this tutorial are not compatible with FlightGear's GPL license. Therefore, it's crucial to use only GPL compliant data for any submissions.

In conclusion, creating custom scenery for FlightGear on Linux using TerraGear requires careful attention to detail and an understanding of the licensing requirements. By following these steps and guidelines, you can create your own unique scenery and contribute to the FlightGear community.
