Daudzdimensionāls karte s tiek izmantoti, ja mēs vēlamies kartēt vērtību ar taustiņu kombināciju. Atslēgai var būt jebkura veida dati, tostarp lietotāja definētie. Daudzdimensiju kartes ir ligzdotas kartes; tas ir, tie kartē atslēgu uz citu karti, kas pati saglabā atslēgas vērtību kombinācijas ar atbilstošām kartētām vērtībām.
