Key Localities Gully Remediation (NESP TWQ 2.1.4, CSIRO)

Key Gully monitoring localities (headcuts and monitoring instrumentation) and outlines of the properties within which they are located. The data in presented in this metadata are part of a larger collection and are intended to be viewed in the context of the project. For further information on the project, view the parent metadata record: Demonstration and evaluation of gully remediation on downstream water quality and agricultural production in GBR rangelands (NESP TWQ 2.1.4, CSIRO)

Methods:

Key Gully Localities were extracted from the 2017 or 2018 RTK GPS surveys for each gully site (see Site_Configuration_and_Survey).

Property Boundaries were generated by extracting polygons from the 2016 Digital Cadastre Database (DCDB) and simplifying to a single polygon. Area in hectares was calculated and appended to polygon attributes.

KMZ’s are exported version of the original ArcGIS shapefiles

Format:

This data collection consists of two shapefiles (zipped) and two equivalent KMZ files with the following names:

NESP_Gully_Key_localities
Key gully localities include the RTK GP location of the instrumentation and the RTK GPS location of the nickpoint in the gully headcut rim.

NESP_Gully_Property_Boundaries
Boundaries for the properties on which the paired control/treatment gullies are located.

Data Dictionary:

Attributes for Property_Boundaries.shp include property NAME and the area in hectares (AREA_HA).

Attributes for Key Locations include
X,Y (MGA94 Z55) and Z (AHD)
Timestamp associated when RTK surveyed
Type- HEADCUT, INSTR
Survey – type of survey and year, APPROX is best guess from Lidar or GoogleEarth
Site_Code – short form code for sites where
MIV = Minnievale
MV = Meadowvale
MW = Mount Wickham
SB = Strathbogie
VP = Virginia Park
- Treatment/Control

Property – Full name of property
Treat_type – Treatment or control
