I have been working with the DEM of South Carolina and I am not able to see from the metadata what is the vertical of the DEM.

How do I identify the vertical datum from the attached screenshot of the metadata?

The attached image is a screenshot of the metadata

  • Welcome to GIS SE! It seems like it doesn't have a defined vertical datum. – Gabriel De Luca Dec 3 '19 at 0:03
  • Pictures of text are less than optimal, since they are not legible on all devices, and not free-text searchable. Datasets based on Clarke 1866 are immediately suspect, because that was the default datum used by Arc/Info before systematic projection files were common. You should probably research the history of this metadata before accepting it at face value, and should definitely try to test for validity. – Vince Dec 3 '19 at 4:16
  • What version of Arc are you using? I seem to recall that Arc desktop was not "vertical-datum aware" [my phraseology] until 10.4.1 or possibly 10.6.1. Perhaps the lack of a vertical datum listing is due to your version of Arc. – Stu Smith Dec 3 '19 at 5:44
  • What is the source of this DEM that you have? Is it a USGS 10 meter DEM? If so, see here usgs.gov/faqs/…. – GBG Dec 3 '19 at 15:06
  • Thank you all for suggestions! I got the DEM from the department of natural resource website of south Carolina – Camilius Dec 4 '19 at 3:15
