Gidday thanks for all the advice -heaps of goodies here - and apologies for
the delay
My original question was "Hi all, any pointers to some (cheap) software out
there that will allow me to orthorectify aerial images"
++++++++++++++++++++++++++++++++++++++++++++++
read an article in GIS User about an inexpensive kiwi product:
<http://www.gisuser.com.au/GU/NEW_PRODUCTS/5_03_NP.html>
Content was:
====
CompuWarp
A new product from NZ-based Compudigm is claimed to have the ability to
bring better quality image registration to desktop mapping systems.
Registration is the process of overlaying an image such as an aerial
photograph onto a map to enable it to be viewed concurrently with other
datasets.
The new product, CompuWarp, is given a bitmap and set of points on the
bitmap whose location on the map is known. It then creates a new bitmap that
has been stretched and twisted in the correct way to overlay onto the map.
The product is an advance on desktop mapping tools that uniformly rotate and
stretch the display of the original. This means that with any more than
three registration points, the fit at the points is only approximate.
CompuWarp creates a new image where all the registration points are placed
exactly.
CompuWarp is suitable for MapInfo and ESRI users, as it accepts the
registration points in MapInfo and ESRI format, and creates the new bitmap
complete with a MapInfo and ESRI registration file.
Compudigm says the product has a number of applications particularly
relevant to local government. It is already in use at Waimate District
Council in New Zealand. Enquiries to Mr Craig Soper

PCI Geomatics has a software package called OrthoEngine, an easy-to-use and
complete product that addresses your needs for producing high-quality 2D and
3D geospatial information for your GIS, CAD, and mapping applications.
Here are some pointers to some of our products that may fit your
requirements.

Maybe try Photoworks. Its inexpensive and it works pretty well. There
are some image
size limitations however. Take a look below.

A usefull ArcView extension that can do that is "Orthorect", written by
Todd Jackson. Here's his descripton:
"Summary:
The OrthoRec extension allows a user to orient an aerial photograph, and
then create an orthophoto using a digital elevation model. The extension
also has a comphensive help document in HTML format. (See the README.TXT
files for information on installing the program and help files.)"
I believe that you need the Spatial Analyst extension for this tool to
work.
Here's the link:

If the link doesn't work, look for it on http://arcscripts.esri.com/ .

Manifold was mentioned but ...
"Manifold cannot "orhthorectify" images - my mistake. I
confused georegistration of orthorectified images with orthorectification."
++++++++++++++++++++++++++++++++++++++++++++++
And here is the tech discussion that followed............
I found a really detailed article on that topic:
