Manage location coordinates

A Location carries a history of coordinate measurements rather than a single fixed point, so re-surveys accumulate over time. One measurement can be flagged as the primary spatial value and one as the primary elevation value — those are what the rest of Erde uses to place the Location. You manage them on the Location's Coordinates tab.

Before you start

• Permission: You need permission to add or edit data on the Site that owns the Location. Editing or deleting an existing measurement requires edit access.
• Prerequisites: The Location must exist — see Add a location and its field artifact.

Steps

1. Go to Data Management → Sites → {your Site} → Locations → {your Location}, then select the Coordinates tab.

2. Select Add. The Add Coordinate dialog opens.

3. Enter the measurement. Provide a coordinate, an elevation, or both — at least one is required:

   Field	Required	What to enter
   Measurement Status	Yes	Defaults to Measured; also Planned, Estimated, or Verified
   Coordinate X, Coordinate Y, Coordinate System	Conditional	The horizontal position; the X/Y pair is required unless you provide an elevation. The coordinate system fills from the Site's default — pick one only if the Site has no default.
   Elevation + Elevation Unit	Conditional	The vertical position; required unless you provide a coordinate
   Horizontal Accuracy + Horizontal Accuracy Unit	No	Survey accuracy of the coordinate
   Vertical Accuracy + Vertical Accuracy Unit	No	Survey accuracy of the elevation
   Primary Spatial	No	Make this the Location's primary coordinate (requires a coordinate)
   Primary Elevation	No	Make this the Location's primary elevation (requires an elevation)
   Collection Method	No	How it was measured — for example GPS, Survey, or RTK GPS
   Measurement Date	No	When it was measured; a future date is allowed only when the status is Planned
   Measured By	No	Who took the measurement
   Notes	No	Optional notes

4. Select Save. The measurement appears in the list.

Result

The Coordinates tab lists every measurement with its status, position, accuracy, method, date, and the Primary Spatial and Primary Elevation flags. The flagged primary values drive where the Location appears on maps and in spatial exports. Edit or delete any measurement from its row menu.

Troubleshooting

Symptom	Cause	Resolution
Saving reports a coordinate or elevation is required	The measurement has neither a coordinate nor an elevation	Enter at least one of the two
Cannot set Primary Spatial / Primary Elevation	The measurement has no coordinate / no elevation to make primary	Add the missing value, or set the primary on a measurement that has it
Saving rejects a future Measurement Date	Future dates are allowed only for the Planned status	Set the status to Planned, or use a past or present date
