Which was more difficult to determine (latitude or longitude) and why?

Longitude, it proved more difficult to determine because longitude was based in the concept of time, making clocks an important variable in navigation.. The time and distance in addition to the use of the sextant for latitude proved more difficult than measuring the latitude. & with latitude You just find latitude by finding the place on the map and see what line it is between or on. (: i got these answers from , answer.com & my math book btw cx

It's either -limiting factors or -scarce resources but i'd go with my first answer since the food and water are abundant they really aren't scarce
