Georeferencing Aerial Images
(OP)
Hi Everyone,
Is there a quick way (or software that I can use) of displaying the coordinate system of particular aerial image file? Also, if I have aerial image that is setup in, say, UTM coordinate system, is it possible to convert it so it is refereced in state plane coordinate system? Is this an easy process?
Thanks in advance.

First, I gather that you have an electronic file of an aerial photo. if it is in .jpg, tiff, .gif or any other commonly used graphic file format you may find the inexpensive program , OziExplorer useful. You can import your photo into the program and then scale it to whatever scale would be convenient for you, provided you know the coordinates of at least three points.

You can get coordinates ( Lat and Lon ) in GoogleEarth. You can also get Stare Plane coordinates from USGS Quadangle maps and convert these to UTM or Lat/Long if your accuracy requirements do not require great precision.
As for State Plane coordinates you should be able to get information on those from your State DOT or any knowledgable Surveyor in your local area. Without knowing what State you are in I can't be more specific.
There may be other ways to accomplish what you are trying to do but those possibly require expensive GIS programs and knowledge of how to use them.
good luck

You might also try...
MapWindow (http://www.mapwindow.org)
SAGA (ht
ILWIS (http://52north.org)
I think each has georeferencing capabilities (may require add-on/extension) and each is completely free.

Remember to check for accuracy after the conversion.
