MARC recordEvaluation of remote sensing techniques for ice-area classification applied to the tropical Quelccaya Ice Cap, Peru / Todd H. Albert.
| Title: | Evaluation of remote sensing techniques for ice-area classification applied to the tropical Quelccaya Ice Cap, Peru / Todd H. Albert. |
| Author(s): | Albert, Todd H. |
| Date: | 2002. |
| In: | Polar Geography. (2002.), Vol. 26(3) (2002) |
| Abstract: | Investigates methods for determining glacier extent from satellite imagery, evaluating several techniques to delineate ice cover through application to the tropical Quelccaya Ice Cap, Peru. Applies each technique to a previously geometrically and radiometrically corrected single image. Evaluates results in terms of accuracy and human operator time required. Recommends three methods for future use with Landsat imagery. Finds band-ratio technique most cost-effective for determining ice-covered area and supervised spectral angle mapper algorithm most accurate. |
