The program is proposing to create a new file for your geometrically corrected images. The difference between the proposed location and the actual values you entered is called the residual. If you are re-starting a new correction based orthoengine previously saved orthoengine, you can open the image file again with the Open Image toolbar button.

By default this file will: Select Geometric Correction from the Processing Step pull-down menu. The objective of collecting GCPs is to accurately position the cursor over a location on the image that you can identify orthoengine a map.

Now position the cursor exactly over the identical location in orthoengine vector image. Based on the points that you have given it, the program has calculated a polynomial transform a mathematical equation that it can use to convert your data from image coordinates to your orthoengine map coordinates.

Now orthoengine the cursor exactly over the identical location in your geocoded image. Go back to the image to make sure you positioned the cursor as accurately as you could. Orthofngine read the coordinates for this point from your map as accurately and with as most precision as possible. The problem I have is that when I try to set the projection to that in the Orthoengine file Orthoengine 84 I get an error message stating that the output georeferencing must be projectable.

When you are satisfied with your selections, click Correct Images. Enter rothoengine coordinates into the appropriate section of the GCP Collection window. When the Project Information panel appears, fill in the following: Using the same projection settings the dialoog completes with no errors. Re-read the map coordinates to verify what you have entered.
