Revolutionizing geospatial analysis through an innovative coordinate system for equitable land-water distribution and landform assessment
摘要
This study presents an innovative approach aimed at rectifying geographic coordinates to foster an equitable distribution of land and water between the eastern and western hemispheres. The primary goal is to identify new coordinates that offer an impartial representation of landforms, water bodies, and terrain. To achieve this goal, we selected Mecca as the reference point for Earth's coordinates instead of Greenwich and redefined the east and west meridians to balance water and land distribution. We then used the Topographic Position Index (TPI) to accurately classify landforms in the eastern and western hemispheres based on this new reference point. Additionally, advanced modeling techniques, including Markov, Cellular Automata (CA)-Markov, and Long short-term memory (LSTM) methods, are employed to forecast drought levels for the year 2042, leveraging a drought index. Results reveal that coordinates at latitude 21.25 degrees and longitude 39.49 degrees demonstrate the most balanced distribution of land and water between the eastern and western hemispheres. The specific outcomes of landform classification in these adjusted coordinates showcase a more uniform distribution of diverse landform classes. Furthermore, predictions from the study highlight the likelihood of severe drought conditions in 2042, particularly in the left hemisphere of the new geographic coordinates. These findings underscore the imminent challenges related to water scarcity and drought in the left hemisphere, emphasizing the imperative for proactive water management strategies.
