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. | A useful resource at this stage are websites that allow you to get the coordinates of a point from aerial photographs.

Once, 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. An easy way do this is with the [[UFO]] "airplane". In addition to making it easy to move around (or hover), it allows you to place objects and see what they look like there. It calculates the positioning details for you and writes them out in the correct format. See [[Howto: Place 3D objects with the UFO]]. 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. 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, and note the <tt>ground-elev-m</tt>. If you want to place the object above ground level, then add the appropriate number of meters. Then, go to the <tt>/environment</tt> key and write down the tile number (current-tile-id). | Start FG and fly to the location where you want to place the object.
