APPLICATION OF MOD13Q1 REMOTE SENSING IMAGES IN ASSESSING THE FOREST STATUS IN THE CUU LONG RIVER DELTA

Abstract

Abstract: In the field of environmental monitoring and natural resource management, remote sensing is considered an effective tool for observing objects on the Earth's surface and monitoring their changes over time. MODIS image data provided freely by NASA, with high temporal resolution and extensive coverage, enables the monitoring of various objects over a wide area. This study uses MOD13Q1 image data with a spatial resolution of 250m with a 16-day repetition cycle, captured in 2022, to calculate and evaluate the forest status in the Cuu Long river delta, combined with field investigations and surveys within the research area to enhance the accuracy of the research results. The study results assessed the forest status and created a forest status map of the Cuu Long River Delta in 2022. Through field surveys, ground investigations, and MODIS remote sensing images, the results obtained are highly reliable. This indicates that the application of MODIS remote sensing images with low spatial resolution (250m) to assess the forest status over a wide area is entirely suitable.
