DescriptionIn the new millennium, Forest Inventory and Analysis (FIA) will deliver most of its database information directly to the users over the Internet. This assumption indicates the need for a GIS-based estimation system to support the information delivery system. Presumably, as the data set evolves, it will free FIA and the users from exclusive estimation within political boundaries.
A data set of basal area measurements from a survey unit in Georgia is used to simulate one that might have been obtained had an annual inventory been conducted over a 5-year time interval. The simulated data set was used to investigate various estimators and any potential spatial correlation of basal area. The presence of spatial correlation, coupled with a desire to fulfill user needs to obtain estimates over individually defined elements of the spatial-temporal cube, forms the basis for an argument that a real-time GIS-based estimation system should be developed as the main information delivery vehicle for FIA.
