OBJECTID: System-generated unique identifier for each record within the feature class.

SOURCE: Organization that provided the data.

NAME: Name associated to the GPS Monument by the number at which it was recorded.

INSTALLDATE: Date of installation for the real-world feature represented in the feature class.

ELEVATION: Elevation recorded during monument placement, above sea level.

XCOORDINATE: The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair.

YCOORDINATE: The vertical value in a pair of coordinates. How far up or down the point is. The Y Coordinate is always written second in an ordered pair.

DISTANCE1: This is the footage distance from the described location in 'Distance1Description' field.

DISTANCE2: This is the footage distance from the described location in 'Distance2Description' field.

DISTANCE3: This is the footage distance from the described location in 'Distance3Description' field.

AZIMUTH: An angular measurement in a spherical coordinate system. The vector from an observer to a point of interest is projected perpendicularly onto a reference plane; the angle between the projected vector and a reference vector on the reference plane is called the azimuth.

BEARING: The actual (corrected) compass direction of the forward course of the aircraft. In land navigation, a bearing is the angle between a line connecting two points and a north-south, or meridian.

DISTANCE1DESCRIPTION: This is the described location from which the distance is collected as a total of 3 location points.

DISTANCE2DESCRIPTION: This is the described location from which the distance is collected as a total of 3 location points.

DISTANCE3DESCRIPTION: This is the described location from which the distance is collected as a total of 3 location points.

ROUTEDESCRIPTION: General description for where the marker is located in reference to known locations.

MARKERCATEGORY: The way in which the marker is placed for GPS such as being placed in an aluminum disk set in concrete which is found physically in the ground.

MEDIALINK: URL for a website related to the record.

PRODUCTIONNOTES: Technical notes from GIS personnel.

DESCRIPTION: Statement illustrating the feature.

CREATEDBY: Name of the person logged into the system that GIS automatically stamps as the original creator.

CREATEDDATE: Date/time stamp from the moment the GIS record was created.

MODIFIEDBY: Name of the person logged into the system that GIS automatically stamps as the feature is modified.

MODIFIEDDATE: Date/time stamp from the last moment the GIS record was changed.

SHAPE: System-generated geometry type of the feature.

Shape.len: System-generated length of the feature.

GlobalID: System-generated unique identifier for each record that is required in replicated geodatabases.
