"Invalid floating point format" When Entering NAD83(2011) Coordinates #2

Open Zian opened 2 years ago

Zian commented 2 years ago

I tried to convert a NAD83(2011) coordinate to WGS84 (transit) and repeatedly got "INPUT ERROR - Invalid floating point format".

The error occurred even when I copied the coordinates from the National Geodetic Survey website.

Steps to Reproduce:

  1. Get a coordinate from the National Geodetic Survey
    1. Go to https://geodesy.noaa.gov/NCAT/
    2. Select the following radio buttons:
      • Horizontal
      • Geodetic lat-long
    3. Enter a lat-lon in degrees-minutes-seconds:
      • Lat: N 32-55-57.38406
      • Lon: W 117-13-05.22344
    4. Select NAD83(HARN) as the input reference frame.
    5. Select NAD83(2011) as the output reference frame.
    6. Click the Submit button.
  2. Go to https://geodesy.noaa.gov/cgi-bin/HTDP/htdp.prl?f1=4&f2=1
  3. Select NAD_83(2011/CORS96/2007) as the input value reference frame.
  4. Select WGS84 original (Transit) as the output reference frame.
  5. Select the decimal year radio button
  6. Enter an input position reference date of 1991.35
  7. Enter an output position reference date of 2002.50
  8. Select the Latitude, Longitude, Height radio button
  9. Copy the degrees from the Output Coordinate (Latitude) section of the NCAT website and paste them in the Latitude box.
  10. Add a space to the Latitude box.
  11. Copy the minutes from the Output Coordinate (Latitude) section of the NCAT website and paste them in the Latitude box.
  12. Add a space to the Latitude box.
  13. Copy the seconds from the Output Coordinate (Latitude) section of the NCAT website and paste them in the Latitude box.
  14. Confirm that the Latitude box says "32 55 57.40258"
  15. Repeat steps 9-13 for Longitude
  16. Confirm that the Longitude box says "242 46 54.75774"
  17. Click the Submit Query button

I expected to see WGS84 coordinates. Instead, the website displayed the following error:

INPUT ERROR - Invalid floating point format, EXAMPLE = 101.1 Run Terminated.

Could this be because you didn't include a Z value? The form doesn't list that as optional. Ran your query with an arbitrary 123.00 as Z and it succeeded.
