Brian: Yes that sounds like a start. Just sitting here thinking that keeping elevation date flexible will be important meters/ft and on ft there is decimals or inches.

Feet really is a pain! Isn't that why the whole world went metric?

Thereís a few of us in America that wishes we were metric. Great times when companies mix standard and metric components on the same equipment.

The machine shop i work in uses a mix like that standerd/metric threads standerd dimensions that are obviously converted from metric. But it is the reality. Flexability is nice. Hopefully this is the easy part all the other stuff youve mentioned sounds like the hard part.

Very feeble first attempt. Ripped apart agopengps to create this. Its crude as can be - but is the concept workable? Thoughts?

The bottom elevation side profile can autosize for length but can add buttons to max out vertical resolution. Once a desired line is drawn, then you can calculate how far above / below the desired line you actually are.

Looks great for a first step!

I am assuming this is constructed with the assumption that there is only one antenna and it is on the cutting point? Shouldn't be any problem with that as long as you are not running a train of scrapers.

Yes, but more could be added.

The simplest setup would be to just put the antenna on the dozer blade or scraper apron.

So is auto steer even needed?

Good grief that's insanely close to the meal ticket already!

The nice thing with GPS is you can drain with the curvature of the earth rather than flat grading or flat sections like you would with a laser.

So with that looking at your examples with GPS your "flat sections" would just get cut you your set slope minimum.

With a laser you would either set it on one plane and cut all the corner's off (moving more dirt than needed) or resetting the laser for each plane (PITA).

That's something for the consideration for the design part of the software.

Auto steer as well is nice when your ditching or other earth works.

Think it's already looking good!

i'd focus without auto steer to keep it simple and working. can always add it later.

I've used agps and they always made you start at the low end vs the high end of the ditch. not sure why...suppose to identify negative slope situations?

1)being able to insert a preferred slope minimum would be beneficial (suppose 0 could be to create a flat surface?)
2)during the calculation of the cut path, an alert to pop up if it can not meet minimum slope preference
2A)option to override and accept cut path if minimum slope preference is not obtainable
2B)Have a few ditches that have 0 slope or small low spot in the middle of a run that is already lower than an outlet. Need to be able to bypass these situations and have a slope that will overlook these occurrences.
3)eventually tracking/labeling of ditches to each field?
3A)I think to speed up development this would not be needed.
4)a information box with estimated material to be removed.
4a)Nice to have an estimate how long it would take you to create a new ditch or estimate if its worth the time to drain a spot.
5)offset from "bottom of cut"
5A)this is a nice feature to help feather the slope or sides of a ditch out. being able to enter a offset distance and selecting how many times to offset works great. Believe AGPS generated addition offset cut lines in the side view of the ditch profile that were different colors from bottom of cut.
5B)also nice if your trying to take the tops out of the ditch. otherwise you may end up trying to cut a foot+ deep in some locations
6)A dummy 3 (or more) light tree light (top color red, middle green, bottom light red) to identify blade height in relation to current blade height.
6A)this is a nice visual to identify when driving too fast for the hydraulics to adjust to the depth and speed that's being cut.
