Abstract
The Phase II Lake Surveys of the U. S. Environmental Protection Agency's (EPA) National Surface Surveys, were conducted on a probability subsample of the Phase I Lake Survey sample. The design allowed estimates to be made both by double sample methodology and by direct probability estimation. The paper describes the adaptation of double sampling methodology to the objectives focusing specifically on the calibration issues involved in those procedures. The Phase II Data Analysis Plan includes specification for the calibration protocol to be used in the case of single Phase II strata, and for simple, one-to-one prediction equations. For more general and complex prediction equations, the general protocol was indicated, but some details were not supplied; these are given here. Also, the issue of calibration in the case of mixed strata is addressed.
