Ställ in arean per prov, kärnorna och det djup som din regel begär. GeoPard placerar punkterna i ett rutnät eller per zon, ruter promenaden, skriver ut etiketterna och tar med sig planen till fältet på en telefon.
En planeringsreferens byggd på officiella källor, inte juridisk rådgivning. Regler gäller beroende på jurisdiktion, näringsämne, markanvändning och program: kontrollera den aktuella officiella texten och ditt laboratoriums instruktioner före fältarbete.
