William Alexander Posted December 2, 2006 Share Posted December 2, 2006 What are the typical units for topo line elevations? Metric... Have a project that requires site topology and I really just need a good idea of what the increment of meaure between lines is. Right now don't have enough information to even guess. Could be 1m .1m...?????? WDA Link to comment Share on other sites More sharing options...
Koper Posted December 2, 2006 Share Posted December 2, 2006 I think its 5 meters, I might be wrong that is 5m Link to comment Share on other sites More sharing options...
William Alexander Posted December 2, 2006 Author Share Posted December 2, 2006 Holy Cow.... 5m????? That's a bit steep don't you think, given the site attached? LOL It's in Denmark, not the swiss alps How's about .5 meters? That'd be typical of the US 2' surveys. I don't have any reference pictures or a specific location of the site for google world to get a better feel. I haven't done any work for this region of the country, so call me a stupid american....I'd rather make sure before I model the site if it is 5 meters...we got some Steep Terrian Thanks, though WDA Link to comment Share on other sites More sharing options...
Ernest Burden III Posted December 3, 2006 Share Posted December 3, 2006 First of all--did the file open in CAD as flat? Often the topos are at height, so just ID the polylines to get the numbers. And whomever provided the file knows nothing about it? But beyond that its safe to say that the major lines (every-other) aren't more than 1 meter. Look at the parking lot, lowest portion on your image. If the interval were 2 meters per major topo, one side of the lot would be about 7 feet higher than the other. That wouldn't work. A rise of 3 or 4 feet would be OK, so I'm thinkinking your majors are 1 meter, the minor 500cm. Link to comment Share on other sites More sharing options...

The majors and minors are seperate splines....when opned in Max. I'm not re-installing ADT just for this. More greif than it's worth to get it re-activated yada yada yada.... They guy who provided it...works at a TV Station that the work is for. He got it from the developers who in turn got it from the Architect....anything new LOL? My guy is away for a week, it's the weekend..... I just need some level of comfort before starting on the site. SO I asked Good chance the project will go Matte from Photographs around the site. It's so Much easier when you are close in topography to get a faster/better match for the Matte Work. I'm leaning the 1 & .5 meter direction...proper slope for the parking ect... Thanks Ernest!

Well its either right or its wrong. The thing is, you can't really go all that wrong by modeling the site to an assumed 1m major. If the interval end up being something else, a linear scaling will fix the site. Curb heights would get scaled, too, but it would probably be only a small adjustment. Save a selection for the tops of the curbs just in case. Link to comment Share on other sites More sharing options...
AJLynn Posted December 3, 2006 Share Posted December 3, 2006 If the lines are 1m I'd think the paving would have to be regraded with retaining walls - look at the parking lot, there would be spaces with a 1:6 slope... Link to comment Share on other sites More sharing options...
Ernest Burden III Posted December 3, 2006 Share Posted December 3, 2006 there would be spaces with a 1:6 slope... Every OTHER line being 1m Don't any of us have anything better to be doing on a Saturday night? Or at least, don't the rest of you have anything better to be doing? I'm obviously a lost cause. Hum, I think you're right, 1:6 or 1:7. Too steep. Then they would have to be 250cm/500cm. So a parking space crossing a few lines would seem more like 1 or 2 feet rise.

Koper Posted December 3, 2006 Share Posted December 3, 2006 hehehe, sorry, got the flue and was asleep when I said 5m, wasn't thinkin straight. 0.5m sounds beter. Link to comment Share on other sites More sharing options...
Ernest Burden III Posted December 3, 2006 Share Posted December 3, 2006 ended up shooting pool. I ain't no fool Shooting pool sounds pretty good. I left my que at a friends house, to force me to go back and play on their table. But I haven't seen them (or my carved-handle, mother-of-pearl inlaid que) in months. Like I said--lost cause. I have a foot injury and I have to stay off my feet If my wife reads that she'll see that I suffer a computer injury. Link to comment Share on other sites More sharing options...
William Alexander Posted December 3, 2006 Author Share Posted December 3, 2006 Crap.....1m exisitng grade overlaying the 'proposed' site. Looks like I get to get the virtual earthmoving equipment out. Those 'orange' areas are stepped retianing walls Scaled (measured) the elevations after the site mesh was done preparing to match bldg footprints....it's obvious now, although at .25 meter those would be decent parking areas Hey Ernest you ever find your que, your welcome to come to Dallas and shoot pool with Myself and Jay Garcia (C4D Guru). You'd really 'appreciate' the project we're working on...also. Airfare is cheap, lodging free,..............although the wife's opinion of a weekend getaway to shoot pool and talk shop- priceless? Thanks for the assistance gentleman, it really did help WDA Link to comment Share on other sites More sharing options...
