I'm having issues with my Lat and Long being rejected by the NGS conversion software.

Does anybody have any ideas what I could be doing wrong?

I am entering in DMS as shown, which is how it arrives in an OPUS-RS report

"degrees, minutes, seconds and decimals (xx xx xx.xxxx)"

XX XX XX.XXXX

XXX XX XX.XXXX

DATE: July 15, 2014

POINT 1
LAT: 43 36 40.43423 0.004(m) 43 36 40.46425 0.004(m)
E LON: 273 27 48.57772 0.008(m) 273 27 48.54398 0.008(m)
W LON: 86 32 11.42228 0.008(m) 86 32 11.45602 0.008(m)

ORTHO HGT: 180.087(m) 0.017(m) [NAVD88 (Computed using GEOID12A)]

POINT 2

You are not the only one. Every time I use that I have to do the example and change the numbers. The first time I enter something it always seems to be rejected. The difference in my area is almost too small to mess with most of the time, but at least I say that I did it.

I will say this, very happy to have the conversion tool though. For the longest time I could find no conversion between NAVD and IGLD. Finally found a single webpage published though the Detroit army corps and ran with that info for years until I found this tool.
