A friend and I are working with remotely sensed imagery and need to extract surface reflectance values for a specific set of points. I did so using QGIS and he did using Google Earth Engine, but our values are much different (the values extracted from Earth Engine were much higher than the values extracted from QGIS). We used the same images, set of points, and surface reflectance bands. In QGIS, I used the point sampling tool, and in Earth Engine, my friend used the function sampleRegions. Does anyone know why this might be happening?
