I am a Research Mathematical Statistician and Emeritus Scientist, retired from the US Forest Service (USFS), Rocky Mountain Research Station, Fort Collins, Colorado USA. I develop data-synthesis methods for the USDA national Forest Inventory and Analysis (FIA) Program. Methods combine time-series of sample-surveys with field plots and samples of high-resolution aerial imagery; full-coverage satellite data (Landsat, MODIS); and simple deterministic demographic-models. I implement methods with numerically-robust algorithms and statistical-software. These multivariate techniques reliably accommodate thousands of estimates (statistical tables) across a small number of annual time-steps.
