<b>Definition.</b><br/>Abstract object that holds the common attributes of the different types of Growing surfaces. A Plot is a continuous surface.<br/><br/><b>Remark.</b><br/>Different types of growing surfaces are:<br/>- Field<br/>- CropField<br/>- ActivityField<br/>- CadastralField<br/>- ExperimentalPlot<br/>- Greenhouse<br/>- ? Tablet ?<br/><br/>
Attribute
Private QuantityType
  Area
Details:
Mandatory=O
MinMax=0-....
Resolution=0.0001
Unit=ha.
Notes: <b>Defintion.</b><br/>The area of the Plot (Activity/Crop)Field.<br/><b>Remark.</b><br/>The area can be calculated from the border, but there are cases where geo information is not relevant, but the area still matters.<br/>
Private DateType
  BeginDate
Details:
Length=10
Mandatory=M
Notes: <b>Definition.</b><br/>The date at which the Plot, (Task/Crop)Field starts.<br/>
Private DirectPosition
  CentreOfGravity
Details:
Notes: <b>Definition.</b><br/>This is the position of the centre of gravity of a Field, CropField, ActivityField.<br/><br/><b>Remark.</b><br/>The CentreOfGravity is intended to give a global indication of where the Field is located. As long as it is used for this purpose, there is no need for a complex, accurate calculation. An accuracy in the order of meters will suffice.<br/>
Private CodeType
  Country
Details:
Notes: <b>Definition.</b><br/>Defines whether the Plot / Field is located in the Netherlands or another country.<br/>
Private String
  Designator
Details:
Length=1-32
Mandatory=M
Notes: <b>Definition.</b><br/>The designator given by the farm enterprise.<br/>
Private DateType
  EndDate
Details:
Length=10
Mandatory=O
Notes: <b>Definition.</b><br/>The date at which the Plot (Task/Crop) stops to exist.<br/><br/><b>Remark.</b><br/>TaskFields and CropFields will stop to exist when the growing season ends. A Field stops to exist when when the borders of the field change.<br/><br/><br/><b>Discussion.</b><br/>Should a Field stop to exist when it does not longer belong to the farm enterprise, or shall the new owner continue to use the original GUID (as this by definition stays unique).<br/>
Private IdentifierType
  PlotIdentifier
Details:
Length=20-32
Notes: <b>Definition.</b><br/>The global unique identifier to identify the Plot.<br/><br/><b>Remarks.</b><br/>1) The PlotGUID of a Plot is given by the farm enterprise that has the rights to use that field, generally over a longer period as owner or long term rent contract. The PlotGUID of an ActivityField and a CropField is given by the farm enterprise that actually uses the field during that growing season. <br/><br/>2) The PlotGUID is unique over all the years. This means that an ActivityField and a CropField will be assigned a new GUID, even when it occupies exactly the same surface as the season before.<br/>3) A PlotGUID is unique worldwide. See the definition of the GlobalUniqueIdentifierType.<br/>
Private IdentifierType
  ThirdPartyPlotIdentifier
Details:
Notes: <b>Definition.</b><br/>An Id given by an other party as the farm enterprise.<br/>
Private DirectPosition
  XY_Coordinate
Details:
Notes: <b>Definition.</b><br/>The XY coordinate of a position on or within the borders of the field.<br/><br/><b>Remark.</b><br/>The coordinate system is specified in the pos.<br/>
