Abstract
The provided is a tidal flat extraction method based on hyperspectral data. The method includes: acquiring and preprocessing hyperspectral data; calculating a constraint condition; calculating, according to the constraint condition, a normalized difference tidal flat index (NDTFI), generating a sample index statistical box chart, and determining a tidal flat extraction threshold according to the sample index statistical box chart; and removing a misclassified pixel based on a coastal buffer zone and a high spatial resolution image, thereby achieving final extraction of a tidal flat. The method has the following beneficial effects. The method is an effective supplement to the existing tidal flat extraction methods. The method adopts an easily realized process, improves the accuracy of tidal flat extraction, reflects the real spatial distribution of the tidal flat, and provides a scientific basis for tidal flat management and protection.
