Earth Point Batch Convert
Posted by field-dog on February 24, 2024 at 10:13 amI’m trying to convert an SPC file of property corners to latitude and longitude and mark the corners on Google Earth Pro. I’m not sure if I’m following the instructions correctly. When I select “Convert” I see the progress bar moving, but I’m not receiving a converted file. Please see the attached SPC file.

Have you tied NCAT by NGS (https://www.ngs.noaa.gov/NCAT/)? It does it pretty easy.

I know that I’m not helping by saying that I would use StarNet to do that. Create a control file of your SP coordinates, run it, and export a KML. Duck Soup.
If you can convert your SPCS coordinates to WGS ’84, they should drop right a Google earth overlay. Their lat/long coordinates are based on WGS ’84.
Keep in mind that your SPCS coordinates, depending on where you are, either based on Lambert Conformal Conic or Transverse Mercator.

@ scotland
Thanks. Have not tried NCAT.

Thanks. Unfortunately, we don’t have STAR*NET.

Thanks. I’m in SPC zone Florida East (0901). The exclusion of the leading zero in my attached Excel file (in the “Zone” column) was likely the problem encountered by Earth Point. My wife has been helping me learn Excel, a very useful tool for surveyors. I couldn’t figure out how to add the leading zero.

I’ve added a “.txt” extension to the attached file so that the website will accept it. Rename the file and open it in Google Earth. This took me less than 5 minutes.
