Large area management

[igi_pop]

Hello!

I'm fishing for some practices, advice, or just ideas on managing a large area.

I'm working on a project, or a study lets say, that involves an area of maybe close to 100 square kilometers.

Now, we got the DEM tiffs, and I've segmented the work across 5 drawings with several surfaces each to avoid the MMS files. When i d-ref them all into one drawing, all is well, I DON'T have performance issues, and I would know how to deal with that.

Problem is, my profiles will be spanning across the entire valey, and i have no idea (so far) on how to label them in the databand 🤷‍:female_sign: As we all know,  it's two profiles maximum.

Creating a composite surface will omit all the divisions I've done, and likley make the surface a bit less "workable". Altho I might end up with that, one surface from point clout (I already made it via gis), and dref it.

Or just make strips of the surface that follow the alignment.

Does the source of creation have any impact on the final size of the dwg and workability? For instance, does it matter if i make it from tiffs, or point cloud, or something 3rd? I suspect it's all the same in the end.

So, to point out my question again, how to label elevations of multiple sampled surfaces in a profile view?

Is there a reasonable workflow?

Thanks,

Iggy

We have a profile label set that we use for labeling both EG and FG in a Band at the bottom of the Profile View.  We station the profile in the Band too, labeling every 100' with the elevations at the Major and Minor Grid Lines, every 20' and 100'.  It's just a simple Band style that you need.

I think the idea of making a "strip surface" is the way to go. If you know the alignments will not be moving this would work well.

I would offset the alignment 1' on either side, turn these into Featurelines getting their elevations from the existing surface. If you don't make a temporary composite surface you'll need to break up the FL's to overlap each individual surface I guess.  Then use these FL's to make a very narrow surface that follows the alignment. Then if you make a profile it will consist of the one surface and not all of them.

Yea. I have an idea on how to go about the strips, and yes the alignments won't be moving.

I'm just probing for ideas 🙂

that being said, i got a notification that the surface from point cloud was created, but i'm still waiting for the "release" so i can continue working. mind you, if it stays alive, i'll just save and d-ref the beast 🙂

Cheers,

Iggy

Thanks for pitching in!

It won't work, the surfaces are next to each other, and continuing on the profile view one after the other. I don't know of a way for one band to display let's say 10 consecutive surfaces on one profile view.

Hey all!

Just to update all readers.

I've managed to create a whole surface, as i said some 100sqkm, and saved the file. I just had to do it to see if it's workable on any level. THe resulting DWG was some 1.3GB, with a 3.2GB mms companion.

I wanted to do it all, and write it down here to have a frame of reference for future questions and ideas. And yes, it's not workable. I mean, you can do whatever, but closing, opening, refreshing, saving...just no.

So, strips it is. @jroot supported the idea, and it works well. But since we're doing geology, it's larger strips.

I took the longest profile, ~10km, and a width of 600m, and created a surface directly from the point cloud using a data boundary.

Now, the DWG size is ~negligible, and the mms for that strip is ~190MB. And, as expected, all works fine and dandy.

Now the setup is such that for display purposes i have the whole area in some 30-ish drefs, that can easily be turned of or whatever.

And for "math", profiling and such, a dref-ed strip.

When it gets to a point where contours need to be delivered, maybe i'll just GIS it, or whatever.

I'll still follow up if anyone comes up with something interestin!

Thanks for reading 🙂
