Polygon data fields

Polygon data can be edited on the Polygons Grid View of the Polygons Grid or the Polygon Definition Page of the Polygon Property Sheet. You can also keep notes about a polygon on the Notes Tab of the property sheet.

Further information, including units details, about all the Network Object fields stored in the Master Database can be found in the data fields topics listed in the Network Data Fields topic.

Fields that are common to the majority of objects can be found in the Common Data Fields topic.

The following table describes all polygon specific data fields.

Field Name	Help Text	Flag	Grid	Property Page	Size	Precision	Units	Database Field	Data Type	Default	Error Lower Limit
Polygon ID	The name of the polygon	YES	YES	1	30	0		polygon_id	Text
Category ID	You can add the polygon to a category. Select a category from the dropdown list. Polygon Categories are defined on the Polygon Category Grid View in the Polygons Grid.	YES	YES	1	30	0		category_id	Text
Polygon Area	Polygon area default value calculated from polygon geometry.	YES	YES	1		3	WN_PA	area	Double	1	0
Number of Properties	The property count for the polygon. Enter a value manually, or generate the information from GIS address point data or from existing network demand data. See Property Counting for more information. Can be used in conjunction with the Specific Consumption and Polygon Area fields to override Land Use object demand values when calculating Land Use demand using the Property Density calculation methods. See Allocating Land Use Demand to Nodes for details.	YES	YES	1		0		property_num	Double	0	0
Occupancy Rate	A multiplier used to convert the Number of Properties value into an estimate of Population. The value used will depend on the source of the Number of Properties data	YES	YES	1		1		population_factor	Double	2.4	0
Land Use	Add ID of Land Use	YES	YES	1	30	0		landuse2_id	Text
Specific Consumption	Daily consumption per property. Can be used to override Land Use object demand values when calculating Land Use demand using the Property Density calculation method. See Allocating Land Use Demand to Nodes for details.	YES	YES	1		2	WN_QD	spec_consumption
Land Use Demand	Total demand for the land use area. Can be used to override Land Use object demand values when calculating Land Use demand using the Land Use Demand or Demand Density calculation methods. See Allocating Land Use Demand to Nodes for details.	YES	YES	1		4	WN_DQ	total_demand
Population	A read-only field generated from Number of Properties multiplied by Occupancy Rate	NO	YES	NO		3		population	Double
Points	An array of X/Y values giving the geometry of the polygon.	NO	YES	NO		0	XY	boundary_array	Array
InfoNet Unique ID	The InfoNet Unique ID and InfoNet Network ID are unique identifiers associated with the corresponding object and network in an InfoNet database. When importing from InfoNet, these identifiers can be copied from the InfoNet database in order to maintain links between the two networks.	YES	YES	NO		0		asset_uid	GUID
InfoNet Network ID	See InfoNet Unique ID	NO	YES	NO		0		asset_network_uid	GUID
