I stake out points for geological testing. Typically they are at intervals from 5-250??. Every job I have ever done they are in a straight line and I just build a pre plot coordinate file and then stake out the points.
We have a job coming up where the customer wants us to follow along the edge of a S shaped road. There will be about five miles of points at 100?? intervals. While I could manually measure and create them in a preplot file it would be very tedious doing 265 of them.?ÿ

I am using trimble access. Is there a way to easily just do this on the fly with the data collector? Go to my start point and number it 1 and then have it tell you when you are 100?? away to the next point and number it 2 and so on? I can think of several ways to do it using multiple steps but I am wondering if there is an easier way.

The easiest way I can think of would be to go out and shoot the start and end points, PIs and PTs, and POCs, then build an alignment and stake to that. Building the alignment in Access is possible but very tedious; I'd do it in TBC or CAD.
What you're suggesting would actually work fine... I'm assuming that 100' doesn't have to be balls on and that the arc and chord distances are close enough to the same that you can stake 100' chords. Shoot your first point, then stake to it... go 100' along the road, shoot your second point, then stake to it, etc., etc. Toggle between Point Staking and Measure Points using the Trimble button on the DC.
You'd probably want to shoot obvious PCs and PTs and adjust accordingly; in other words, if you staked a point and it was 40' to a PC, you'd probably want to shoot the PC then stake a 60' chord on the curve.
I'd probably just stick the rover out the window and topo the road and use that to make an alignment.
Yes I was planning of driving the road with a rover to see where it is but I am not sure how to create points at a fixed interval along that line.?ÿ
As long as you have an FXL file that allows for line coding you should be able to observe points along the road using a line code and then stake to the generated line. Like @BStrand suggested, it would probably be sufficient to first drive the road with a rover sticking out the window taking a shot every so often (could use continuous topo for this).
Stake to line is pretty straightforward. It essentially treats the target line as an alignment, so you input 100 feet as the station interval; once you stake the first point, it should automatically stake out to 100 feet up the line, and so on.
?ÿ
Can you set your stakeout to use polar and distance - then you can just stake the last stored point and be 100 feet away from the last point
I have a leica and there are several settings for how to represent the staked location - so the sun, last point, a stored line, etc
I know the 5700 Trimble you could do this, I am sure the newer models kept that option.
Thanks guys. I think the stake to line is what I was looking for. Continuous topo the road to get the line. Then go to one end and set the first point and do a 100?? interval. I will try a test run this afternoon on a smaller scale.
No need to create points, just make your first topo point station 10+00 and stake at 11+00, 12+00, etc.
You could even use your shots along the road to create a horizontal alignment. Then you could stake intervals on an offset from the road if needed.?ÿ
If it's a road with S-curves, as you stated, then you need to create and stake to an alignment. You don't need to create points for each stake location, you need to stake an alignment at 100' stationing.
Somewhere in this thread we went from staking a curved road to a straight line... two very different things.
Just wanted to give an update as we got it surveyed and are doing our testing now. While exploring ??continuous topo? which I had never used before there was an option to either take a reading at a time or a distance interval. I chose distance and 100?? and went to the start point and drove the road slowly. It created points every 100?? as I drove. I exported these to a csv, created a new job, imported them and stakes them out. It worked beautifully and was simple.?ÿ
?ÿ
There are a couple issues with this method the first is you can??t really stop fast enough to mark a point when you are doing the initial driving so staking them out separately is necessary and secondly since you are moving the distances are not precise. ?ÿIn my case we are contractually obligated to report where we actually did our test submeter but we have about 12?? leeway in the location we choose to do it at so it worked perfectly.
