Abstract—Last few decades there are lots of changes in Southeast Asia land cover due to development, industrialization, increasing population, socio-economic activities, and food demands. This research work analysis the maximum likelihood supervised classification approach for Southeast Asia land cover mapping and changes at 30m resolution from 2010 to 2019 using Landsat 8 OLI (Operational Land Imager) satellite data. The resulted maps cover eight land cover classes as barren land, cultivated, developed (built-up area), forest, grassland, shrubland, water, and wetland in Myanmar, Laos, Vietnam, Thailand, Cambodia, and North Malaysia Southeast Asia countries with very high accurate informative information. The resulted maps and information in this paper are very useful to researchers, regional to a national and international level decision and policy makers for sustainable development, fortification of natural resources at the same time protection of fragile eco-environment in Southeast Asia so that they will utilize in future.

1. INTRODUCTION In the last few decades, there are rapid changes in Southeast Asia land cover due to development, industrialization, and the rapid growth of population, socio-economic activities, which also increase the demand of food [1]. These changes directly pressurized the natural resources in the region in terms of deforestation, encroachment, increase cultivation and production, ultimately rise miss-use of land. This miss-use of land increases the vulnerability of the area and in the last, this is the main cause of climate change in the region [2, 3]. Earlier studies develop global level land cover maps but they are low to moderate resolution [3, 4]. They have valuable information but still missing lots of information due to low resolution [5]. The purpose of this research work is to develop high-resolution land cover maps and their trajectory since 2010 to know the main cause of changes in the natural resources in Southeast Asia. It is not an easy task to develop a high-resolution land cover map based on remote sensing satellite data in Southeast Asia as its cover large
