An Evaluation of Classification Methods for Level II Land-Cover Categories in Ohio

The purpose of this research was to evaluate six classifiers applied to Landsat-7 data for accuracy of Level II land-cover categories in Ohio.These methods consist of (1) USGS National Land Cover Data;(2) the spectral angle mapper;(3) the maximum likelihood classifier;(4) the maximum likelihood classifier with texture analysis;(5) a recently introduced hybrid artificial neural network;(6) and a recently introduced modified image segmentation and object-oriented processing classifier.The segmentation object-oriented processing (SOOP) classifier outperformed all others with an overall accuracy of 93.8% and Kappa Coefficient of 0.93.SOOP was the only classifier to have by-class producer and user accuracies of 90% or higher for all land-cover categories.A modified artificial neural network (ANN) classifier had the second highest overall accuracy of 87.6% and Kappa of 0.85.The four remaining classifiers had overall accuracies less than 85%.The SOOP classifier was applied to Landsat-7 data to perform a level II land-cover classification for the state of Ohio.
