General / GCP Error as function of distance from GCP
« on: January 12, 2018, 06:40:06 AM »
Hey,
We have a few questions regarding GCP error:
- How does error increase as a function of distance from the GCP?
- How should GCPs be placed to meet a certain accuracy requirement? Should GCPs be placed closer together to increase the accuracy of a site?
- Does significant elevation differences on the site require an increase in the number of GCPs?
- How much elevation difference is allowed between GCPs? Is that even a criteria that needs to be considered?
- Is there a mathematical equation that can define error as a function of distance from the nearest GCP?
Thanks,
Madhav M.
