NCGS Location Sources

Pre-release. This site describes standard version 0.7.0-dev, which is in development and may change before version 1.0.0.

How a site’s point was obtained. A site location record carries one source; the site’s current point is derived from its location records (ADR-0021).

Field GPS

A fix taken by a device at the site’s gate or centroid, with the accuracy the device reports.

Office map placement

A point placed on a map or aerial image away from the site, with the placer’s estimate of its accuracy.

Verified on site

A point checked by an observer standing at the site’s gate or centroid, confirming or replacing an earlier one.

This page explains the standard and does not decide conformance: only the released corpus does. It describes glossary/site-schemes.ttl at standard version 0.7.0-dev.
