Sampling Frames

  • Constructing area frames (AF) using satellite imagery, topographic maps, and aerial photos. Adaptation of existing digital materials for the purposes of the AF is another option.

  • Constructing list frames and implementing multiple frame sampling (MFS). During this stage the survey timing and the sample approach for the list frames are defined.

  • Calculating sample allocation and sample selection using optimum design. This system works in principle as a nested analysis of variance. The design is based on probability sampling and it is robust enough to allow for optimal sample allocation, emphasizing cost reduction and control of non-sampling errors.
