Id | CompoundIdentifier | 1 | |
Description | string | 1 | |
FieldId | Integer | 1 | |
SpatialData | MultiPolygon | 1 | (Shape descendant class) |
TimeScopeIDs | Integer | 0..* | Should include validity range. 20151103: Changed to 0..* for more functionality and for compatibility with name. |
Headland | Headland (a child class, really) | 0..1 | The temporal component (i.e., headlands changing over time) will be taken care of via the FieldBoundary object titself: leverage the timescopes of the FieldBoundary, and create a new field boundary if/when the headlands change. |
GpsSource | GpsSource | 1 | |
OriginalEpsgCode | String | 0..1 | Documents the original spatial coordinate system of the data if it was recorded in something other than WGS84 (indicating the points have been re-projected) |
InteriorBoundaryAttributes | InteriorBoundaryAttribute | 0..* | The need is to be able to mark if the interior rings in each polygon are passable or not. Each interior ring will have an (integer) ID. We will use the M attribute to store the shape id. Here we would include a reference to a dictionary linking these IDs with:

ShapeIdRef | Integer | 1 | This Id is going to correspond to the M value of the multipolygon rings of shape data. |
IsPassable | Boolean | 0..1 | 20151103 Changed Passable to IsPassable, for clarity |
Description | String | 0..1 | 20151103 Changed Name to Description, for consistency |
