Measuring inclines?
What is the best way to measure an incline using your iPhone?
When I told my husband that measuring inclines was part of the survey, he pointed out that to avoid distortions and small undulations, the best way is to use a longer plane and put the phone on that. So I'm thinking of using my walking pole fully extended and placing my phone on that.
Are there any youtube videos that explain how best to measure inclines?

Hello
I used an inclinometer app on my phone - easier than doing the maths.
I did use a "longer plane" - I just carried a plank of wood with me as I don't use a walking pole. And the plank meant that I could actually balance the phone on it. I think I do need to carve and colour the plank for next time as I looked a bit of plank myself carrying a lump of timber from Wickes on a countryside walk!
I think there is a video linked from the Surveyor training for manual measurement but we've got it easy using metric measurements. Use a 100cm plane held horizontal with one end touching the ground and measure down from the other end to the ground vertically. If that measurement was 100cm you'd be looking at a 100% include - so if it's only 26cm then it's a 26% incline. Easy.
But laying the plane on the ground, balancing your phone and reading the measured incline is arguably easier :-)

Thanks Neil,
And to add more information on this, my husband showed me how to complete this using the tangential calculation.
I used my pole to straighten out the incline - it came to 10 degrees, which I logged.
Back home I used a calculator and entered '10' then hit 'tan' - this gave me 17.63... multiply by 100 and you get 17.63%.
This is much quicker than using a plane and ruler.
