Column Detail

KeyString

Unique identifier for each table entry.

NumRows

Number of rows in this grid. For seismic grids, the rows correspond to the crossline axis of the 3D survey.

Extent

The extent defined by four points representing the maximum bounding box of the feature representation's shape. Clients should always set the coordinate system when retrieving this column so they know the exact coordinate system the points are returned in; otherwise, the points will be returned in the default coordinate system and each vendor store might have a different default. The points are ordered based on the row/column coordinate space. The annotations for the points are always returned in the following order: (minColumn = 0, minRow = 0) - grid origin, (maxColumn = NumColumns-1, minRow = 0), (maxColumn = NumColumns-1, maxRow = NumRows-1), (minColumn = 0, maxRow = NumRows-1). The returned point's X value is the horizontal axis value (i.e. columns). The returned point's Y value is the vertical axis value (i.e. rows). Since Grid2d represents a two-dimensional "surface" mapping the third coordinate for each point will be zero since this coordinate represents the Z axis. The points are returned based on the CoordinateSystem if a coordinate system is not provided.

OriginValues

The origin will be either a single EpiSeismic_SeismicGeometry3d identifier for a seismic grid or a EpiInterpretation_Grid2d identifier for a non-seismic grid. There is a one-to-one relationship between this column and the OriginTypes column.

GridOrder

Identifies how the 2D grid is ordered in the vendor store.

PrimaryZPropertyName

The z-value property name. If the name is empty, it means this horizon feature representation does not have a z-value property. The primary z property identifies the property that contains the time or depth values that represent a surface. The other properties are usually attributes that are "draped" over the surface.

NumColumns

Number of columns in this grid. For seismic grids, the columns correspond to the inline axis of the 3D survey.

OriginTypes

Identifies the grid origin. Seismic grids will be associated to a SeismicGeometry3d. Non-seismic grids will be associated to a Grid2d.

PatchName

Name of the individual pieces that compose the whole. An empty string indicates the vendor store does not support patches.

PrimaryZPropertyKey

The z-value property key to the HorizonGrid2dProperty table. If the key is empty, it means this horizon feature representation does not have a z-value property. The primary z property identifies the property that contains the time or depth values that represent a surface. The other properties are usually attributes that are "draped" over the surface.

HorizonFaultBoundarySet

Identifies the HorizonFaultBoundarySet (fault polygon collection) associated to the HorizonGrid2d if one exists.
