Selecting Representative High Resolution Sample Images for Land Cover Studies. Part 2 Application to Estimating Land Cover Composition

We tested the effectiveness of the Purposive Selection Algorithm (PSA, described in the companion first article) to accurately estimate land cover composition over a large area. The knowledge of land cover distribution over large areas is increasingly more important for numerous scientific and policy purposes. Unless a complete detailed map is necessary, a sampling approach is the best strategy for determining the relative proportions of …
