Locations can be obtained from other datasets, existing mapping, tourist publications, organisations, Local Government websites or other source material.
Capture in the direction of flow to maintain the linear drainage network.
Capture down the centre of the feature, if required extend the features length to a minimum of 25 metres
For features greater than 25 metres in width capture as a Waterbody Area with a Feature Type “Watercourse Area” and a Function of “Spillway Area”

UNDERGROUND CONNECTOR

(see function “linear connector”)

Definition: An artificial line used to connect water features underground, where the path is generally known but not visible. Connection could be through pipes or natural seepage.

Alternate Terms: Underground pipes

Capture as a 2D polyline as function “linear connector”
Location is plotted from orthorectified imagery.
The underground location is difficult to determine.
Capture in the direction of flow the best interpretation of where the feature could be located or as a straight line joining the visible ends of the watercourse features.
If the end point of the connector cannot be determined, an assumption is not made as to where the watercourse may flow, and a connector will not be captured.
Do not capture where the Feature Type “Culvert” would be more appropriate to use.

WATER SUPPLY LINE

Definition: A constructed watercourse used to enable the transfer of stored or available water from one area to another.

Alternate Terms:

Capture as a 2D polyline
Location is plotted from orthorectified imagery.
Locations can be obtained from other datasets, existing mapping, address details, tourist publications, organisations, Local Government websites or other source material.
Capture down the centre of the feature for features less than 25 metres in width and show a minimum length of 150 metres.
For features greater than 25 metres in width, capture as a Waterbody Area with a Feature Type “Watercourse Area” and a Function of “Water Supply Channel”.

Waterfalls

A point feature class displaying the location of waterfalls.

Attribute Schema:

Waterfalls
A point feature class displaying the location of waterfalls.
Column Name	Nulls	Format	Size	Description	Constraints
FEATURE_TYPE	No	Text	50	Unique feature type that identifies the type of feature. Options: Waterfall
NAME	Yes	Text	100	The name of the feature (if available)
ALTERNATE_NAME	Yes	Text	100	An alternate name of the feature if available from the Queensland Place Names Database, otherwise left blank.
QLD_PNDB_ID	Yes	Long		Queensland Place Names Database unique identifier
ATTRIBUTE_SOURCE	No	Text	100	If the feature is named, the attribute_source is the source imagery, map, or data from which the features name has been obtained. If the feature is not named, the attribute_source is the source imagery, map, or data used to define what the feature type is.
ATTRIBUTE_DATE	No	Date		Date of the source imagery, map, or data used for attributing the feature.
ADDITIONAL_NAMES	Yes	Text	100	The feature may be commonly known by other names or have different spelling. Multiple additional names can be shown and separated by a comma.
ADD_NAMES_SOURCE	Yes	Text	100	The source map or data that the additional names were obtained. Multiple sources can be shown, separated by a comma. If multiple sources are shown, the written sequence will be the same as the written sequence of the names themselves.
FEATURE_SOURCE	No	Text	100	The source imagery, map, or data that the spatial location of the feature was obtained from.
FEATURE_DATE	No	Date		Date of the feature source information that the location of the feature was obtained from.
DRAINAGE_BASIN	No	Text	50	The name of the drainage basin the feature is situated in.
PFI	No	Text	15	A Persistent Feature Identifier (PFI) is generated for each feature at the point of creation in the database. The value of the PFI will stay with the feature through all changes to the feature (both spatial and non-spatial) until the feature is retired. (See Persistent and Unique Feature Identifiers)
UFI	No	Text	15	A Unique Feature Identifier (UFI) is generated for each new feature at the point of creation in the database (at this point the PFI and UFI will be the same). The value of the UFI will stay with the feature through all changes to the feature (both spatial and non-spatial) unless the feature is split into multiple other parts. If the feature is split, the separate parts will retain the original PFI but new UFI’s will be generated for the split parts. (See Persistent and Unique Feature Identifiers)
CREATED_DATE*	No	Date		The date the feature was originally captured and first loaded to the database *internal use only
LAST_EDITED_DATE*	No	Date		Date of the last editing or revision to the feature *internal use only
UPPER_SCALE	No	Long		The upper scale for which the feature should be considered suitable for digital display	dm_upper_scale
TEXT_NOTE	Yes	Text	50	For mapping purposes. Additional annotation that can be shown on a map. If the feature has no name, then transfer its stated type/function (typed in lower case) into this field e.g. e.g., waterfall
ADD_INFORMATION	Yes	Text	255	A comment field (additional information)

Feature Type definitions:

Waterfall - A place where a sudden change in the bed of a watercourse causes the water to fall almost vertically.

Upper scale:

1:25 000 – unnamed waterfall
1:100 000 – named waterfall

Capture Process:

WATERFALL

Definition: A place where a sudden change in the bed of a watercourse causes the water to fall almost vertically.

Alternate Terms: Fall

Capture as a 2D point.
Location is plotted from orthorectified imagery.
The waterfall point is to be snap to the watercourse line and be coincident with the identified edge of the ledge or vertical drop.
Reference the elevation from the highest resolution DEM and existing LiDAR over the area.
The name is obtained from Queensland Place Names dataset.
Locations can be obtained from other datasets, existing mapping, tourist publications, Local Government websites or other source material.
