You can either build the GUI [http://gitorious.org/fgscenery/terrageargui/ from source], or download a pre-compiled build:
* [http://liveries.flightgear.org/terrageargui/ Windows builds]
Please note that you need to download/compile a recent version of [[TerraGear]] as well.
==== For GNU/Linux users ====
# Set your FlightGear's root ([[$FG_ROOT]]). This is used to retrieve the list of available terrain materials.
==== Downloading data =Download ===Specify boundaries in the boxes on the left and , or select an area on the map. Next select a source to download shapefiles for that area. Note that OpenStreetMap only includes line date (roads, rivers), so you'll need some polygon data for the actual terrain. Both [[World Custom Scenery Project|Custom Scenery]] and [[CORINE]] (only Europe) provide that. The GUI downloads and unpacks the package to your <tt>{project's directory}/data/</tt>.
Alternatively you can download shapefiles from [http://mapserver.flightgear.org/download.psp the mapserver by hand]. Unpack the downloaded file(s) to your <tt>{project's directory}/data/</tt>.
===== Elevation data =====[[File:HGT tiles example.png|thumb|An example of HGT file tiles.]]
Elevation files are optional, but of course required to generate scenery with elevation offsets (even flat countries like the Netherlands need elevation data, since no country is completely at sealevel. Simply select a data source and then click the button to download the HGT files that span your specified area. The original source is usgs.gov, but a cleaned variant of the same data is available from fgx.ch (see [http://downloads.fgx.ch/geodata/data/srtm/README.txt the readme] for more information). The data will be saved in in <tt>{project's directory}/data/SRTM-3</tt>.
===== By hand =====
[[File:HGT tiles example.png|thumb|An example of HGT file tiles.]]
Downloading tiles by hand is somewhat tricky. If your scenery has a boundary of:
{| class="wikitable"
# Click on the bottom left boundary wanted and report the displayed value in TerraGear GUI. (i.e: if Google Earth value is "W9_N42", report Minimum Latitude value "42" and Minimum Longitude value "-9")
# Click on the top right boundary wanted and report the displayed value in TerraGear GUI. (i.e: if Google Earth value is "E6_N45", report Maximum Latitude value "45" and Maximum Longitude value "6")
 
{{note|You need to use a reasonable boundaries because mapserver.flightgear.org contains a limit.}}

'''Note: with recent TerraGear builds, it is required to add the used material-names to the default_priorities.txt file.'''
The fgfstg-construct tool brings all your gathered data together, throws it in a washing machine and spits it out the otherside in a format ready for use with FlightGear. Click the "Update list" button to populate the field with all decoded shapefiles. In the list you select all types that you'd like to include in your scenery.
After clicking the "Generate scenery" button, it may take a long time for TerraGear to finish. Depending on the size of the area you are creating the scenery for and the level of detail in your shapefiles. Simple and small sceneries will take a couple of minutes, where larger, more detailed areas can take over an hour! So trying new things on small areas first will save you a lot of time.
=== Requested features ===
* Visual map for boundary selection.
* Multi-threading, so the GUI doesn't freeze when running a process.
