Lat and Long Precisions

[ToddRogers-WPM]

I have a customer who needs to have a precision of 5 decimal places for Lat and Long.  Currently the style can be set to 4 (0.0001). 

Anyone know of a way to get 0.00001?

You'll need to go to the drawing settings > ambient settings > lat long and up the precision. You will also need to update the text components of any label styles or make new ones for any labels that you want to show the extra precision.

[ToddRogers-WPM]

The ambient settings does not reflect the label itself.  In the label style, there is only the 4 decimal place precision.  Making a new precision is what I would like to do.  Any suggesions on how this is accomplished?

"The customer is always right." is bull dukey! Tell them you are in civil engineering NOT tool and die. Sounds **** to me. Are they on the equator and splitting hairs?

[ToddRogers-WPM]

I agree.  It's airport work.  Total different animal.

Oops. I see I've been censored. I didn't think something that rhymed with banal was that bad. After all there are quite a few of us in civil who get a little too much of it now and then

Hi Todd, I had a client ask the same question just today (5 years after you :-).

Did you ever find a way to get 5 decimal places of precision for Lat Long (they are looking at the Point Table Style)

Thanks,

AWood

@awood Looks like it works in 2017...

Not if you want DDMMSS.SSSSS

[ToddRogers-WPM]

Good call @Jeff_M, that's correct.

0.00001 seconds converts to 2.77 x 10-9 radians.  I don't know what the limit of the internal database is for angular precision, but I'm guessing that you've found it.

I just recently bumped into this situation while creating a Point Table using the SHP Import/Export Point Tables tool. All unit precision is controlled by the ambient settings in the resulting table. And my requirements specifically state 5 places past the decimal point in DMS. This appears to be an issue the Core AutoCAD as the UNITS precision only goes to 4 places as well. (SMH) I'm now wondering how FDOT create a State Kit, that requires a precision that's unachievable.

Reminds me of the HBO movie Doomsday Gun where the Iraqis wanted this arms dealer to build them a weapon that would reach the promised land. Problem came down to U.K. customs. They wanted to know why segments of "oil pipe" were being manufactured to .001 tolerances.

If NGS can publish conversions to 5 places beyond the decimal, I would think that this program would do the same if not more...... I don't think this is an issue of precision as much as it is performance or lack thereof.
