Hi,
This is from a project I completed a few months back.
And I was after some peoples opinions.
I was playing around with the GCP’s and updating vs bundle-adjusting…and I now have some more questions.
When I added the first 3 GCP’s, 9000, 9004 and 9010. The error was only 8mm.
When I added the rest (another 6), and ran a bundle adjustment, the error on each point increased to about 50mm.
What would you do in this situation, use only the 3 GCP’s or more?
GCP 9010 was still the outlier, at >100mm.
If I took out GCP 9010 and re-adjusted, the error reduced to in the 30mm range. But 9010, now a check point was of by 500mm. It was surveyed by someone else, but I don’t think they would have it >0.5m off.
I didn’t want to, ‘falsify’ the results by getting more accurate GCP results but poor check point results? Thoughts?
Thoughts? eg. would you include or remover GCP 9010.
Thanks,
James
