DELWP Core Spatial Data Services Strategy
o Five-year strategic direction for how
DELWP will source, aggregate,
maintain and provide access to
Victoria’s core spatial data
o It reconfirms our focus on being the
trusted source of core spatial data
services for Victoria
o Strengthened by a new focus on
helping government, industry and
the community to generate value
from spatial data.

Importance of a datum
Enables integration of different datasets, measure once, use multiple times

National implementation
GDA2020 is now Australia’s official national datum• Published in Commonwealth Legislation as:
National Measurement (Recognised Value Standard of Measurement of Position)
Determination 2017
• GDA2020 is Australia’s official datum, revoking GDA94
• Effective from 11 October 2017
![Page 18: DELWP Core spatial data services roadshow...4 DELWP Core Spatial Data Services Strategy o Five-year strategic direction for how DELWP will source, aggregate, maintain and provide access](https://reader033.vdocuments.us/reader033/viewer/2022042301/5ecc8d7e460da92cd31bbb5a/html5/thumbnails/18.jpg)
18
GDA2020 drivers
Drivers to adopt a modernised geodetic datum for Australia:
• Plate tectonics and regional deformation
• Alignment with global satellite positioning systems - ITRF
• Significant positioning technology developments
• GDA94 failing to support increasing accuracy needs of users
• Widespread distortions in GDA94
![Page 19: DELWP Core spatial data services roadshow...4 DELWP Core Spatial Data Services Strategy o Five-year strategic direction for how DELWP will source, aggregate, maintain and provide access](https://reader033.vdocuments.us/reader033/viewer/2022042301/5ecc8d7e460da92cd31bbb5a/html5/thumbnails/19.jpg)
19
GDA2020 specifications
• Geocentric Datum of Australia 2020
• Conventional static datum like GDA94 with rigorous uncertainty
• Just like GDA94 — based on ITRF, fixed at a specific epoch:
GDA94 = ITRF1992 @ 1994.0
GDA2020 = ITRF2014 @ 2020.0
• Horizontal shift of approx. 1.6 m NE from GDA94, slightly rotated
• Consistent vertical drop of 0.09 m from GDA94
• AUSGeoid2020
• Projections: MGA2020 (UTM), VICGRID (conformal conic)
• Australian Terrestrial Reference Frame (ATRF), initial release commencing
January 2020

RPAS
What is RPAS?
Benefits to using RPAS
• Supports “eye in the sky” video / thermal imagery
capability requirements
• Valuable for small area capture
• Potential for quick delivery
• Flexibility – “drone in a backpack”
• Supporting new industry / technology

DELWP RPAS Trial
RPAS Trial (2016)
• Investigate legal, regulatory and data management
issues
• planned burn surveillance and other land management
operations
Establishment of 2 RPAS Panels
• Structured and coordinated acquisition and technical
support to use RPAS captured data
• Supports range of DELWP activities including planned
burns, animal welfare, compliance, road and bridge
management.

Challenges and Opportunities
Current limitations:
• RPA Standard Operating Conditions
• Application process delays with Civil Aviation Safety Authority
• Awareness of capability of RPAS
• Cost
• Reliance on external providers for some roles
But…it is a “new” technology and sector with increasing capability and value from data every year

Case Study: Timber Harvesting Compliance
Identified need for aerial imagery to support general
logging oversight and compliance.
Imagery data would confirm:
• Size of specific logging coupes and
• Extent to which the remaining vegetation buffer was
damaged by post logging burns.
Two options: fixed wing aerial imagery capture or RPAS
![Page 65: DELWP Core spatial data services roadshow...4 DELWP Core Spatial Data Services Strategy o Five-year strategic direction for how DELWP will source, aggregate, maintain and provide access](https://reader033.vdocuments.us/reader033/viewer/2022042301/5ecc8d7e460da92cd31bbb5a/html5/thumbnails/65.jpg)

Case Study
Quotes were obtained from DELWPs Coordinated Imagery Program for manned aircraft and one of the DELWP RPAS Panel Providers.
The RPAS provider was scheduled to complete another task nearby and provided options of either standalone or back to back with the other task.
The quotes for the manned aircraft were very similar to the back to back price quoted and it was decided that this was a good opportunity to test the capability and product of the RPAS.
The quote for the standalone deployment were almost twice that of the back to back due to interstate travel for the company and separate CASA approvals.
CASA requires one month for approval processing time for Beyond Visual Line of Sight flights.

Proposed Flight Area
• The purple areas were
provided to identify the
requested logging coupes
to be photographed.
• The while rectangle
(2.5x5km) was a
suggested possible flight
area due to reduced day
light in winter and to
provide 5cm/px resolution.

Understanding Provider limitations.
“Customer to assist in provisioning suitable
launch/recovery locations.”
As a side note, we could be deploying as early as
next week for the other DELWP survey so would
need to know relatively quickly if the Rubicon
survey is to be combined.
“With regards to a suitable launch/recovery area,
the team would be looking for a relatively flat and
clear open area – approximately 100m radius.”
The job was
rushed

Communications
SMS received the day before the flight-
The main risk without having a
relatively flat and clear open area for
the recovery site - is that when the
aircraft comes down under parachute,
it strikes something (i.e. large tree
stump, Boulder, etc) and damaged the
payload".

other members of
the team.

Result
The risk to the aircraft being damaged on landing resulted
in no flights occurring.
The presence of fog was a secondary issue.
Meeting reasonable expenses resulted in $5,500 being
paid as the final negotiated price even with no product
delivered.
