A useful resource at this stage are websites that allow you to get the coordinates of a point from aerial photographs. One such is [http://itouchmap.com/ itouchmap.com], which relies on Google Maps. Enter a street name, city, and state. When you get a good photo of your feature, click on map to place a marker there, then read the displayed coordinates. Google Earth is also a good way to obtain position information, and there are other websites that will provide it also, or you can get it from a GPS. (Coordinates of real-world locations are not copyrightable, so there is no legal problem with using these tools, but don't copy other content, such as images or models!) | A useful resource at this stage are websites that allow you to get the coordinates of a point from aerial photographs.

Once you've got at least a rough idea of the coordinates, you need to place the object visually. | Once you've got at least a rough idea of the coordinates, you need to place the object visually. | ||
Start FG and fly to the location where you want to place the object. Open up the property browser in FG (File->Browse Internal Properties), and the <tt>/position</tt> key. Check that the values for <tt>latitude-deg</tt> and <tt>longitude-deg</tt> are what you want, or write them down if you're positioning things visually, and also note the <tt>ground-elev-m</tt>. If you want to place the object above ground level, then | One easy way do this is with the [[UFO]]. In addition to making it easy to move around (or hover), it allows you to place objects and see what they look like there. See [[Howto: Place 3D objects with the UFO]]. Another easy way is with the [[FlightGear Scenery Designer]]. Both tools calculate the positioning details for you and write them out in the correct format. | ||
Here, though, we'll continue by describing a manual way to do it, for people who may need or want to know the inside details. | |||
Start FG and fly to the location where you want to place the object (or use [[command line options]] to start in that location). Open up the property browser in FG (File->Browse Internal Properties), and the <tt>/position</tt> key. Check that the values for <tt>latitude-deg</tt> and <tt>longitude-deg</tt> are what you want, or write them down if you're positioning things visually, and also note the <tt>ground-elev-m</tt>. If you want to place the object above ground level (or partially bury it), then adjust the number appropriately. Then, go to the <tt>/environment</tt> key and write down the tile number (current-tile-id) for that location. | |||
