Abstract:
|
Probability-based inference has long been traditional for natural resources inventories with preference given to estimators corresponding to simple random and systematic sampling designs. The recent availability of ancillary spatial data from sources such as satellite imagery and digital maps has created opportunities for model-based inference and additional modes of probability-based inference. However, the data from these sources are not always compatible with observations of response variables due to temporal and spatial resolution differences and location and co-registration errors. For data sets consisting of forest inventory plot observations and Landsat satellite imagery, the effects of differences in spatial resolution and location and co-registration errors on probability- and model-based inference are investigated.
