- OC curve is helpful for us to choose a reational sampling scheme.
- Among them, sampling scheme design is the key factor of effecting CFI data quality.
- Hybrid sampling coding with multiple-description is proposed which chooses its local sampling scheme according to DCT high frequency coefficient.
- Based on the test for reliability appraisal, the hierarchical Bayesian method is used to decide the prior distribution of the reliability indices, so that a new Beyesian sampling scheme is got for success or failure mould product in the acceptance test.
- Sampling scheme design, inventory technology and methodology, operational process and many other factors influences the continuous forest inventory (CFI) data accuracy and reliability.
