Land cover describes what covers the surface: trees, water, bare ground, buildings. Land use describes what people do there. A satellite image can provide evidence for both, but a visible surface does not settle every question about its use.
Fields and plantations
Straight boundaries, repeated rows, tracks, and irrigation structures can suggest managed land. Look for several features together. A rectangular parcel does not tell you who owns it, and a green field does not identify the crop. Harvest dates and growth stages can change its appearance.
Settlement and industry
Roofs connected by streets indicate development. Large roofs, yards, sidings, or loading areas may support an industrial interpretation. They do not establish what a business produces or whether a site is operating. Use a land-use map or a named-site reference to check the interpretation.
Forest, water, and ambiguous edges
Tree cover may be a plantation, regenerating woodland, or another forest type. Water may occupy a natural lake, a reservoir, or a flooded field. Shape and context help you propose an explanation; dates and external records help test it.
Try marking a small image with three categories: observed cover, likely use, and unresolved areas. Put your confidence beside the interpretation. This produces a more useful reading than assigning a firm label to every pixel.
