        <h3>Project Overview</h3>

        <p>This WebGIS application presents tree cover change analysis across Salzburg's 6 districts between 2018 and 2024 using Sentinel-2 10m Land Use/Land Cover (LULC) data. Click on any region to view more detailed statistics and trends from over the study period
        <p>You can view this information again at any time by clicking <strong>'i'</strong>  in the bottom right corner of the map.</p>
