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 | 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. 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. | Once you've got at least a rough idea of the coordinates, you need to place the object visually.
