Column Detail

KeyString

Unique identifier for each table entry.

NumRows

The number of row grid coordinates associated to the 2D grid.

Name

Name of the entity.

DepthCoordinateSystem

The grid's default depth coordinate system used for projecting a 3D globe on a 2D plane. Represents a surface mapping in two dimensions of the real world. Equivalent to the TimeCoordinateSystem except for the third axis which is Depth. The TimeCoordinateSystem and DepthCoordinateSystem do NOT have to be the same as the project's.

Extent

The extent in the form of an array of four points which represents the maximum bounding box of the grid. 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). The default coordinate system will be the project's MapTime or MapDepth system. Since Grid2d represents a two-dimensional "surface" mapping the third coordinate for each point will be zero since this coordinate represents the Z axis.

NumColumns

The number of column grid coordinates associated to the 2D grid.

TimeCoordinateSystem

The grid's default time coordinate system used for projecting a 3D globe on a 2D plane. Represents a surface mapping in two dimensions of the real world. Equivalent to the DepthCoordinateSystem except for the third axis which is Time. The TimeCoordinateSystem and DepthCoordinateSystem do NOT have to be the same as the project's.
