文摘
- •
A two-phase strategy for land-cover, land-use estimation is proposed and tested.
- •
The one-per-stratum stratified sampling was used to select the second-phase points.
- •
The precision lost due to the two-phase sampling was evaluated.
- •
The new classification effort was 100 times smaller than the one-phase.
- •
The relative standard errors of the two-phase survey increased about 10 times.
