I have ERDAS Imagine 16.00 here that I have an error.
This error was in the AutoSync and when I did all the GCP for a few of the images. When I click on an image to run the APM and it gave me the error. Said Model can not be solved so I clicked on Ok .
So what does the error mean ?

As per your query, you given GCP on few images any try to run APM(Automatic Point Matching).
This error due to no GCP and Tie on few non-georefrenced images-
1. As i assume, you are following process for Georefrencing process. So i suggest you to provide GCP points(Min.3) on all images.
2. AS i assume, you are following process for Edge Matching process, so i suggest you to provide Tie points (Min. 3) on all images.

First of all, I did use 6 GCP for each image I have. I have 8 unreferenced images. The first time I did use 6 control points for each image and then when I hit the APM and check for the results.
So when I did that then I made a few delete GCP and would run APM again. Some of them showed me the RMSE as a 0.00. I assumed that I would have to go back and try to get them to at least 6 points. Even though some of the image showed me their RMSE numbers like 28.87, 24.25 so just a few of the images showed me 0.

Yes, to make sure they were saved to the right file and also that the corresponding GCPs were not recorded into the wrong row. It's so easy to record them wrong if you miss a click. That's all I can think of. Hope you find the error.
