摘要

The overly coastal development to meet the human pressing basic needs has driven the deforestation of mangrove forests in Belize, causing environmental issues. Thus, understanding spatiotemporal changes in mangrove forests was thus important for evaluating current forest management practices in regard to formulating a better long-term strategy of mangrove ecosystem. This study focuses on detecting changes of mangrove forests using Landsat imageries in Belizean coastal areas during the period 1989-2000 and 2000-2013. The data were processed based on an analysis of the pseudo-invariant features (PIFs) through three main steps: (1) image rectification to account for geometric errors between images; (2) image normalization using PIFs to find out unchanged pixels as a reference data; (3) using pseudo-variant features (PVFs) method to detect mangrove change areas from the normalized images.
