Population Dynamics Monitoring using GHSL Data in Google Earth Engine

In this video, we demonstrate how to monitor population change over time using the Global Human Settlement Layer (GHSL) dataset within Google Earth Engine (GEE). Starting with a point of interest defined by coordinates, we extract and visualize the relevant administrative region using the FAO GAUL boundary dataset. We then load the GHSL Population Image Collection, which provides gridded population estimates for different years. The population data is visualized using a well-defined color palette, showing density from very low to very high. We also create a stacked band image to allow multitemporal visualization of population layers in a single view. To quantify changes, we generate a time series line chart that tracks the total estimated population over time for the selected region. This chart uses the sum of population values at each timestamp to highlight growth trends, making it a powerful tool for demographic studies, urban planning, or sustainability research. This tutorial is ideal for GIS users, urban planners, researchers, and students looking to learn how to extract, visualize, and interpret population dynamics at the regional scale using free and open Earth observation data.
