![]() ![]() I then opened up World Editor, made a new project "heathrow-flightgear", and imported each of these airports using the "Import from Scenery Gateway button". Next, I looked up using TerraMaster by hovering over the zone to see which airports were in the zone. This completes pre-processing of landmass data. zip in data sources, so for another later project I can just go back to data sources and re-extract the shapefile! Note that this overwrites the 530MB shapefile. (I set the transparency of the HGT data to 50% by right clicking it in the layer menu and hitting properties and changing transparency.)įinally, I disabled editing mode by clicking "Toggle Editing" again, making sure to save the data. Then, I re-enabled "render" and saw this: I then inverted selection using this tool:Īnd hit Delete (SUPR or DELETE on most keyboards - alternatively use the red trashcan icon on the toolbar) to delete the data, hitting "Yes". I selected the land_polyons in the layer menu and hit toggle editing, then used the select by area tool to select only what I needed. Alternatively, you can use Layer > Add Layer > Add Vector Layer.ĭon't worry if you don't see anything happen - that's because render is disabled. Then, I made sure that "render" was disabled, and imported it into QGIS using Ctrl + Shift + V (open vector layer). I copied land-polygons-split-4326.zip to data sources, extracted, and again copied the files to a new folder "osm_landmass". This is vital unless you have a supercomputer as otherwise it will try to render all 500MB of data totally freezing QGIS! Once it finished, before I did anything else, I disabled "render" on the bottom toolbar in QGIS. Meanwhile, I was downloading landmass polygons from OSM. gz files containing all the elevation data. This took only a few seconds, and produced a new folder "work", containing SRTM-3\w010n50\w001n51 with many. Next, I opened up TerraGUI and with the following options started to parse the elevation data. I could then delete the un-needed layers in the /data/SRTM-3 folder. Next, I selected the layers that I did not need in the bottom left layers tab, and removem them in the menu opened by right clicking, leaving only N51W001. If it had not been, I would have needed to download layer M31 instead which was farther over to the east. I checked the coordinates to make sure that the area I wanted was included, and indeed it was. If you do not have "load them all", you can instead use Layer > Add Layer > Add Raster Layer or Ctrl + Shift + R to load the. Next, using a handy plugin for QGIS, "load them all", I load the files as a raster layer. Then, I extracted the files and copies them to a new folder. So, I downloaded tile M30 from Viewfinder Panorama and put it into "data sources". Next, I created a new project in QGIS, "EGLL", and saved it in that folder EGLL as EGLL.qgs.įinally, I added all folders in TerraGUI - as such: All other folders will be automatically generated by TerraGear. zip files) and "data" (for extracted files). Under this folder, I created the folder "data sources" (for. I created a new folder in my FlightGear folder - EGLL. Notice that the download buttons are inoperative, since the associated servers have gone offline! 012-vector but I have not yet tried it and don't know if it will workįor the purposes of this tutorial I will be generating a small area around London Heathrow (N51W001 tile) in order to use the new airport layout properly. This will be sufficient for europe - however, for other areas you need to find VMAP files from somewhere - alternatively, many countries do publish their own data sets. Unfortunately, for large areas you need to find out what airports are within the area and import each one by hand. Airport data - available through World Editor by "importing from airport scenery gateway". OSM line data - available from - you can click on continent - country - and in some countries, subregions, then download the appropriate shp.zip file. I downloaded most of these - unfortunately they are huge downloads! Corine data - available from -> under GIS data, there are several. Landmass data - worldwide from OSM at: (531MB) So after installing TerraGear, first thing you need to do is acquire data. I also used World Editor - this is needed to parse data. I also installed QGis 3 in order to be able to edit shapefiles. It contains both the GUI and the main program - for convencience, I will use the GUI. ![]() I got my TerraGear from - this is by BecOzlacan and is very stable and works well. Here is my guide as to how to run TerraGear to generate scenery - primarily focused on windows, but not exclusively.įirst up, what to install. ![]()
