Well I tried google map, using the scale at the bottom, but the picture wasn't update and got wrong results.
How is that possible? The park wasn't there? Or the marks? Find some reference marks, like a building or a light post at a definite direction from start/end and use those.
In the google map the field has a picture of 2 football pitches and the measurements say it is 65m x 55m, but the field now has a bigger football pitch which is 80x50m and there are 3 football pitches in the field now.
I was trying to use anything i can use as a reference but couldn't find any, it is a big field. I just saw a picture of it in 2009 and there was a marking for an athletics track marking, but they removed it due to the uneven surface and slant of the field.
I measured this football pitch, using my steps, size 8, 10 inch log, which was 80m.
That is reliable. However, if you just count your total steps and multiply it by your foot length, you may include some significant error, because your shoe is 10 inches but that does not guarantee that 2 close steps will be 2*10 = 20 inches. May be 19 or 21. So if you extrapolate that to measure 100m ( about 400 steps ) you include that error 400 times. It is better to measure how long a few more steps are, it reduces the error. So if the whole field is 400 steps, don't say it is 400*10inches. Go back home, measure exactly how long 5 little steps are and then the field is 80*that measurement, the math type is ( total steps / number of steps measured ) * number of steps total length.
Interesting, So I will measure how long 5 steps are (keep toe connected with heel of other foot). Ideally it should be just over 1m. But I don't understand why multiply that with 80. as that will be 1.25m x 80, which will be more than 50.
or do you mean measure 4 steps, which should be ideally 1m, then multiply the actual distance by 80m.
So If i was to measure this football pitch, lets say I counted 320 steps. if i was to use the formula you posted, would it be like.
(320/ I'm guessing you are referring to where you said measure actual distance of 5 steps, so this would be 5 or 4) * lets say the total length of the 5 or 4 steps was 1.25 or 1m.
this would give me 80 if i used 4 steps or for 5 steps it would give me 80m as well I see. so If lets say there was an error and the actual measurements of 5 steps was not 1.25m but 1.5m so the actual distance would be 96m.
I understand now, very clever, will see how it goes.
Thanks
