Establish Stakeout Grid Boustrophedonically?

> Any ideas?

Yeah. Hand your party chief the job and turn him loose on it.

What you said ...

Now, there's a word you don't hear every day

I once had an esteemed colleague who suffered from boustrophredonitis. As many of you know, it can be unpleasant, and will affect your family life. After a couple of visits to the local boustrophrenologist, (of which there are many in these parts) he underwent a complete boustrophrenectomy and along with the penicillin shots, it all cleared up. He's fine now.

All kidding aside. There must be some software guru out there who can come up with a routine to label stake-out points in the same manner that the ox plows. It's probably already been done, but is hard to find. Maybe this is a good one for Big E to tackle.

sure

it was all fine until his Wife found out about it and started asking questions about where he contracted it!

How about drawing a P-line - up 11,000 feet, over 25 feet, down 11,000 feet et cetera -and then create points by the measure entity or divide entity or whatever that weird command is that I’ve never had any luck with?

How about stations and offsets.

Yeah, that's better yet. Make the p-line an alignment and then place points at centerline on 25' stations.

An interesting problem - and a new word for the survey procedures manual. Here's how I solved it.

I drew a line 1000' long and then used the Create Point by Measure Object command to create points at 25' intervals along it. Then I copied my line and points 25' over so that I had two sets. The third step is to rotate the copied points by 180 around the midpoint of the line. This gives me the basic layout that you're looking for. If I need more I just keep copying.

I don't know if your DC will do this or not.

But, with the old Lieca system 300 (RTK), and I'm sure there are other DC as well, you can quickly create a grid, with any intervals N-S and E-W. You can have it align in any direction, or along any line. Then you merely walk right up to the next one you want and take your shot.

I've created 50' square grids over a 200 acre site, in the field, in under a minute.

:coffee:

Thanks for the ideas!

The problem with the pline 11,000' long, over 25', and back again is that I need to have them walking cross-ways, not long-ways down the runway... Picky, I know!

I did create a pline that I copied multiple times, and connected the ends, etc, to get the full length, but now I'm in the process of stretching in the areas where taxiways intersect the main runway. Its a pain, but I'm almost done.

Thanks again!

Is there another reason that you are going through all this? It sounds to me that all that the crew will be doing is data collection..

>..as they collect these shots in the field

Why go through all this hoop jumping when any competent crew can pace out 25 foot centers and set up their own way of getting the job done?

Bob

Paul,

The grid layout needs to be tighter than pacing allows. (And because its a challenge to see if I can find a way to do it the way I want!)

Bob

> The grid layout needs to be tighter than pacing allows.

Yeah..right Bob

>(And because its a challenge to see if I can find a way to do it the way I want!)

Why didn't you just say that in the first place? Any cadd exercise you do is going to be ignored when the crew gets out there anyway. The runways probably have poured grid lines that could be used for baselines maybe at 20 ft centers or something like that. LAX is like that and if I remember correctly they were 25 ft squares, but if that's what you want to do Bob..by all means go for it.

"Let them tell you what they want, then give them what they need"

Bob

Paul - You can do it however you like.

In the end, I found another reason to like C3D! I created the first 2 rows of points (numbered how I wanted) at specified intervals, and then used the Array command with the specified interval and angle, and C3D automatically renumbered points as it created new ones along the runway!

The only drawback was not being able to use consecutive numbers in the irregular shaped taxiway intersections. I will just use this same process with different blocks of point numbers for these areas individually.

It's funny how people give useless feedback.
Unfortunately you can't go through the RPLS archives, but anybody who's done a runway knows better than to half-ass it or wing it.

I posted at length about runways and taxiways on the other site and I'm not going to go through it again. But if it's not within tolerance, you will be milling it out. So it would behoove the person laying it out to follow the design grids and elevations as best as they can.

I've done it several times and we used a PaveSet
