NDVI visualization of Garissa and Isiolo using GEE is a powerful tool for analyzing the vegetation health and land cover of these two counties in Kenya. By using GEE's Earth Engine technology, users can access high-resolution satellite imagery of the areas and visualize the Normalized Difference Vegetation Index (NDVI) of the regions. This index measures the reflectance of near-infrared and visible light from the vegetation and can be used to measure the amount of vegetation in an area. By visualizing the NDVI of Garissa and Isiolo, users can gain insights into the health of the vegetation in these regions and how it is changing over time. This information can be used to inform decisions relating to land management, conservation, and land-use planning.
