So I see these coordinates on a project I am working on.
Each represents the center point of a pier footing.
I was interested in checking the distance between the two (& others)
And it occurred to me that maybe if I set my location I could possibly “plot” the locations inside Sketchup?
However, I am not even sure what exactly the coordinates are based on. (GPS/Total Station/Other?)
Anyone have any insight?
I have no idea. However, from the range of the numbers, these are not GPS coordinates. They could be UTM, but there is no zone specified. If I plot them as x/y coordinates, the distance between the two points is 13.944. About right for a 14-ft beam if the coordinates are in feet from some reference point.
Note that when entering the values you could append ’ to get feet directly and then set units to architectural with precision 1/2" to get ~13’ 11 1/2".
That leaves the question of the source of those coordinates. If they are feet they are many miles from the origin! Using them directly in SketchUp is likely to cause problems because SketchUp wasn’t designed to handle things that far from the origin.
I know these type of real world coordinates can wreak havoc in SU, but thought perhaps by setting a location that was very close to these actual coordinates it may not be problematic. (Simple minded I know)
Anyhow…you are correct in advising against it…thanks for that.
I also really only needed to double check the “center point” information being provided by the construction documents I am working from to create Trellis structures and the like. (I have conflicting dimensions on some)
Jim gave me a way to do that…so I think that will suffice for now…thanks to you both.
When I was modeling Los Angeles a few years ago, the coordinates of the lower-left (southwest) corner of the dataset was: 1574050.2501430213 (North) and 6276182.629929781(East). As near as I could tell, the reference point seemed to be some arbitrary location a few miles off the coast in the Pacific Ocean.
