I am processing images in Agisoft Metashape. Images were collected in the Corpus Christi, TX area using TxDOT NTRIP Provider (RTN). In Agisoft Metashape, on the 'Reference Settings', I need to specify the 'Coordinate System' and the 'Camera reference'. These are some of the options available:

  • NAD83(2011)/Texas South (EPSG:6585)
  • NAD83(2011) (EPSG:6318)
  • NAD83(2011) / Texas South Central (EPSG::6587)
  • NAD83(2011) / Texas South (ftUS) (EPSG::6586)

I found this about the local station: enter image description here

I was wondering which one is the most accurate to select.

Example of image coordinates: Latitude: 27.782485 Longitude: -97.560364 Altitude: 15.02

The XYZ coordinates are 3D Cartesian AKA geocentric coordinates. The output coordinates you have are in decimal degrees so they're on geographic 2D, NAD83(2011), not projected at all.
