![]() 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. ![]()
