Recently made a change in the route for next. I went around and mapping the change using the "-GPS dual steps.

Such a measure of change until leaves have a kosher GPS measurement. I asked the Committee and received GPS data.

Hallelujah yagil shouldn't be out in the field and try again. Got the file map yagil and measuring heights.

Here is the correspondence between yagil and:

Yagil:

"The attached map. Note that there is a difference between what the GPS (upper line) why that map shows a height at the same points.

That's quite normal barometric pressure – can lead to deflection of 10-20 m in certain devices. Take a look at the points difference and try

Remember there are no jumps or whether it is suitable for measurement.

My answer:

Hey yagil, thanks for the map. Check the heights and will also compare.

What makes me a measure of distance in my GPS-dual-steps 1.665 miles,

Compared to approximately 1.825 km GPS. A difference of 9%. Compared with the area sown-mishmar haemek measurement

Was more than 5 km and that ups and downs. The difference was only 5%. Following the comparison

This raised the count of duplicate steps for 100 m at 5% (from 66 to 70). As almost all the way down the steps.

Sizzle. At the end of the adjustment process to do FINE TUNING steps and can measure a good precision increases, decreases,

And altitude differences.  ... And you can get GPS for. .. ...

[The new route in yellow, and then also from South to North heights profile]

Interesting. Especially the stuff about the Committee sent you GPS data of the change. This is exactly what I would like to receive the digital information that should be on the Committee.
It is known that GPS data are not accurate in determining height. For the PCT, the Halfmile Project uses information in the calculations for DEM heights for each point. The US has a database open, and in some places in the U.S. the information density is elevation sampling (accurate) about 5 (on the surface). It already gives a very accurate altitudes cut.

You keep referring to digital information for which it is used only to measure the length and profile. In my opinion, good quality raw information can be the basis for a very useful database for each Bill, if it is to develop a useful application or website.

I knew I'd get a professional answer deserves . My post was for entertainment.

I have a mission: azdcha equipment do an accurate mapping to the PCT using double measures.

The major problem with this type of mapping is the memory (at the top). But there's aplkitzia to count steps,

Then I have to purchase unlocked.

About to be a problem but the Jewish head will serve us patents.

If the mapping fails at least go the PCT.
