Lets try a little logic to answer your question.
We will examine two senarios when setting course and then staying on track when navigating VFR and map reading.
Senario number one:
We set course at one hundred feet above the airport runway and fly the trip at one hundred feet.
Obviously remaining right on course will be necessary as our field of view of the ground ( Your track ) will be very limited. And if we wander several miles off track getting re oriented will be a real problem.
Senario number two:
We set course at one thousand feet above the airport and fly the trip at one thousand feet. We now have a far greater field of view to map read our track and wandering a mile or so off track is easy to correct due to our increased field of view.
. .Try starting your mind picture from this simple example of map reading.
Then do not get to carried away with all the exotic problems and solutions that will be part of the training process, in other words don't let bull**** baffele brains as it really is very simple to navigate VFR with the proper map and the proper picture and understanding of what you are doing.
Here is a hint:
Note the point of departure then find the point of arrival, make a fold of your map from the start to the finish of your trip, jump in the flying machine and map read the track by following the fold crease on your map. So you don't even have to draw a line with a pencil or pen....for distance measuring use the side of your thumb to determing milaege. Anyone who trys to tell you that you must be accurate to the mile and to the minute is just missleading you.
