Abstract

Methodology is lacking to easily map Forest Inventory and Analysis (FIA) inventory statistics for all attribute variables without having to develop separate models and methods for each variable. We developed a mapping method that can directly transfer tabular data to a map on which pixels can be added any way desired to estimate carbon (or any other variable) for a particular area. The method uses a remote-sensing layer coverage to stratify forest from nonforest, a standard double sampling analysis, and a definition of spatial variables for summarizing FIA data within the double sampling framework to link to maps. Further refinements are needed but the new method appears to be accurate, flexible, and straightforward.
