View Full Version : Getting Measurements

Okay, I'm about to purchase a measuring wheel this weekend. I'm going to go and take the measurements for one of our local courses. I do have some questions about getting measurements. Now, I'm okay at math, but I'm no whiz. Here are my questions.

When measuring a water shot, how would you figure the measurements for a water carry? Now, I have no Lasers, and All online maps are useless. I've already been down that road. I'm assuming you use the principle of the Triangle. BUT... I've seemed to have forgotten the formula for figuring out the length. It crosses at an angle. ah hell, It's hole 18 on the map (http://www.dgcoursereview.com/course_files/3763/701a412b.jpg) this map.


Second, how would you measure for a \_/ type slope. Only make it more gradual. Someone mentioned this in another thread. A 150ft shot across a v shaped slope, may actually measure out to be 200ft linear.

Any thoughts?


Also, feel free to contribute any measuring tips that are not mentioned on here. All will be appreciated.

I would make it a triangle, measure A and B, and use the formula (A^2)+(B^2)=(C^2).

The attached pic is what I am talking about. Make sure the angle between A and B is right at 90 degrees. It is easier to do than it sounds, unless its woods right there.

Cool! That was exactly what was looking for! The tree line would make it difficult, but I would probably follow the pond. It's actually designed in a rectangle like the picture. Perfect!! Thank you! one question, My math is a little rusty. Is the ^ the symbol for squared?:o

Yes it is, its the only thing I have seen to represent it besides true superscript (?) numbers above the letter.

I guess I could have put it: A squared plus B squared = C squared.

Na, that's cool! I figured it was, but I wanted to make sure!

"This hole sure don't look like 600ft??" lol

Dude, thank you for that! I guess I need to freshen up my math skills again! lol

Another thing you could do is get a long measuring tape, which can be extended straight across water or straight across a U shaped valley hole. They make these in 100', 200', 300', etc. sized reels that you can buy at hardware stores or sporting goods stores. Or failing that, get a spool of kite string, mark the distance on the string, and then lay it out on a flat, straight surface, and measure that length with your measuring wheel.

I would ignore the dip in the V, especially for your location. For a 150 shot to measure out at 200 feet using a wheel, the ditch would need to be 66 feet deep.

Any slope you can walk on won't add a significant amount to the distance.

{If you really want to figure it out, use the right triangles again. For example, say your wheel says 306 feet for a shot that is over a 30 foot deep V. That is two 153 by 30 foot right triangles (think of a T superimposed over the V). 153 feet is the long side (the slopes), 30 is one of the short sides (the depth of the V), so you'd solve for 150 feet for each of the straight across sides. So the shot would be 300 feet. Not far off from what you measure if you ignore the V.}

Accept the fact that no measuring system is going to be more accurate than about 2% off.

I always double check my measurements for reasonableness using Google Earth. You can use this picture (http://stevewestdiscgolf.com/Documents/LorisGE.jpg) which has a 750 foot line on it.

Lewis - I don't know why I didn't think about using string! It's always the simplest methods that are over looked! lol Thanks for that one! :)


Steve - Oh this question wasn't relevant to my area, it was more of just satisfying my curiosity. I don't think there is a hill or gully to be found in my area! lol I like to take nuggets like this, and store them away for future use. I figure that I'm going to be helping out a little bit with the new courses that are being put in here, so I should have my knowledge ready!

get the biggest wheel you can, they're far more accurate.

Actually, I'm going to pick one up this weekend! I just wanted some advice on getting those "Hard to Reach" places.
