Coordinate conversion

Hi M!, Some pointers:

Good Luck

yea.. u need 2 points.. the invers between them can give you a bearing

I take it you are trying to convert coordinates to latitude and longitude...? I'd check with the County Surveors office and see what they have in the way of benchmarks...

(BTW: N 29º 36' 42", W98º 29' 33.1" = NE of the intersection of Stone Oak Parkway and North Loop Texas 1604 West, San Antonio, Texas)

yes, you have only one point there. but as you get into it, here is a snippet out of the middle of some trash I wrote that would select a line and write text for a bearing.

(if a (progn (setq pt (osnap (cadr a) "nea") el (entget (car a)) pta (cdr (assoc 10 el)) ptb (cdr (assoc 11 el)) oldos (getvar "osmode") bear (angtos (angle pta ptb) 4 4) )

it took the endpoints of a line for input.

that help?

Perhaps I did not make my original post clear. I import data from GPS into AutoCAD Civil 3-D. A single point is listed as 13803292.0810, 1979568.8290. My customer wants to know the Lat & Lon of that point. Seems like there would be a button for that somewhere....

Hi M!, Some pointers:

Where or How did you get the result (N 29º 36' 42", W98º 29' 33.1")? That's all I need to know...

Seems to me that your GPS equipment should be able to provide the latitude & longitude of the point.

But, go can to this page for info on converting UTM to Latitude & Longitude:

I have been a surveyor. (N 29º 36' 42", W98º 29' 33.1") is not a result. the units are mixed or something. are you parsing it correctly?

N 29º 36' 42" W could be read 29 degrees, 36 minutes 42 seconds West of North. but then the 98º 29' 33.1" has no meaning. and a bearing means nothing without a distance.

and as for 33.1" - nobody in their right mind reads anything to the tenth of a second.

you are mistaken on one point at least, you do need to know more. compliance here, just ask a better question.
