If you need to manually digitize or "make" a new boundary over the LU2020 imagery:
: Open the Attribute Table of your LU2020 layer and add a new column (Field). LU2020
Depending on your goal—whether you are creating a new spatial feature (like a polygon) or a data attribute (feature engineering)—here are the steps to proceed: 1. Create a New Spatial Feature (Vector Data) If you need to manually digitize or "make"
If you are performing "feature extraction" for a machine learning model (e.g., for LULC change detection ): for LULC change detection ):
