Interpreting imagery

True-color imagery shows visible landscape context. Cloud, smoke, illumination, sensor geometry and missing coverage can affect the comparison. The swipe view does not calculate vegetation change. Quantitative NDVI analysis requires calibrated red and near-infrared reflectance with quality masking.
