well dear latitude and longitude together give a geographical position (location) of any point.. like we have x-y coordinates on a graph whch join to gv a certain point.. same way lat n long combine to give a position (location) of certain point on the globe... now obviously, as far geographical postion is concerned pakistan is not a single point tht means it wud hv thousands of difrnt positions (latitude n longitudes) as u move from one place to other within pakistan...like khi wud hv difrnt geographical position (lat n long) n isb wud hv difnt.. so within a country u will hv various positions (lats n longs).. hope it wud gv some idea! ciao:
