Shikui Peng. (1986). A comparison of replacement strategies in continuous forest inventory. Silva Fennica vol. 20 no. 3 article id 5278. https://doi.org/10.14214/sf.a15457

Three replacement strategies in continuous forest inventory of the Enso-Gutzeit Company have been presented and discussed. The first strategy adopts data from only the last two inventory occasions; the second strategy employs data from all four occasions, in which there are two groups of permanent plots measured on the first three occasions and independently on the last two occasions; the third strategy also utilizes data from all four occasions, but includes only one group permanent plots measured on all four occasions. Results indicate that the last strategy is best for efficiency. The difference between the first two strategies is small.

Shikui Peng. (1987). On the combination of multitemporal satellite and field data for forest inventories. Acta Forestalia Fennica no. 200 article id 7647. https://doi.org/10.14214/aff.7647

The study concerns with the methodology and efficiency of integrating multitemporal satellite image data with permanent sample plots in a continuous forest inventory and compartment wise estimation. The generalized least squares estimation for the population, and the unsupervised stratification for compartments, are the main estimation methods employed. The experimental material is composed of real and simulated multitemporal images (Landsat TM) and field data. Precision analyses for the estimation and comparisons for a number of estimation and updating methods, as well as statistical options are given.

The PDF includes a summary in Finnish.
