Title: Rapid classification of landsat TM imagery for phase 1 stratification using the automated NDVI threshold supervised classification (ANTSC) methodology
Author(s): Cooke, William H.; Jacobs, Dennis M.
Date: 2002
Source: In: Proceedings of the Fourh Annual Forest Inventory and Analysis Symposium, 81-86
Description: FIA annual inventories require rapid updating of pixel-based Phase 1 estimates. Scientists at the Southern Research Station are developing an automated methodology that uses a Normalized Difference Vegetation Index (NDVI) for identifying and eliminating problem FIA plots from the analysis. Problem plots are those that have questionable land useiland cover information. Four Landsat TM scenes in Georgia have been classified using this inethodology. A cross-validation approach was used to assess accuracy. The results are comparect with an alternative methodology: the Iterative Guided Spectral Class Rejection (ICSCR) methodology.
