For a land cover survey on crop fields
At least one photo should be taken of the field, and if possible, at least one photo should be taken at nadir (from right above) showing the ***canopy cover*** of the crop, or at least at an angle that shows the cover percentage.
D'après le contexte, c'est à mon avis l'idée que veut faire passer cette phrase: il
faut une photo montrant la relation entre les cultures et les arbres qui les dominent, peut-être parce que cela influence l'ensoleillement et/ou le rendement
