GIS / Spatial Statistics

Photo Interpreted Maps

Photo Interpreted Sample

These datasets are vector point coverages representing photointerpretation (PI) points that are located along a grid across 13 northeastern states under the purvue of the Northeastern Research Station. At each point along the grid, the photointerpreter assessed various characteristics of the landuse on NAPP 1:40,000 photography, and recorded
them in a database.

This dataset was used by the NE Research Station's FIA unit to choose forest inventory plots and as a first phase sample for stratified random sampling and double sampling
for stratification.

4 types of maps were derived from the PI data:

Go to:A. The type of forest cover.

Go to:B. The volume of forest cover or land use
(volume is a measure of the amount of wood).

Go to:C. The percent crown cover (i.e., the percent continuous
canopy coverage).

Go to:D. The distance to the nearest ecotype (change in forest
