Geomatic Technologies completes Marine Safety Victoria Pilot Project
Victoria, Australia 2008 – Geomatic Technologies (GT),
has successfully completed a pilot data capture project, on
behalf of Marine Safety Victoria (MSV).
Project Brief – Marine Safety Victoria (MSV) engaged GT
to conduct a pilot data capture survey of assets in 6
waterways - the Yarra River, Westernport Bay, Hazelwood
Cooling Pond, the Gippsland Lakes, Glenelg river and
Lake Hume. GT was required to capture and collect data
of each asset mentioned in the zone descriptions in the
Vessel Operating & Zoning Rules of the Marine Act 1998
documentation, for the above 6 waterways. The following
is an example of a Vessel Operating & Zoning Rule
(VOZR) which states an asset used to describe the 5 knot
speed restriction area:
‘The waters of Hastings Bight north of a line extending
south-westerly from a white survey beacon on Long Island
Point to a beacon with a red triangular topmark on
the foreshore approximately 1000 metres south of
Hastings jetty”.
GT was required to find the assets, in this case 2 beacons,
create a polygon of the zone and using GT’s AIMS
Mapping System that was adapted to suit the project
record the following attributes:
- Stipulate the type of asset - Sign, Buoy, Beacon, Marker; or Feature i.e. Jetty,
- Schedule compliance - Correct location, incorrect location or missing,
- Condition assessment - Good, Fair, Poor.
GT was also required to capture imagery of each asset.
Project Solution - GT utilised an MSV vessel and
together with MSV who provided knowledge of the
waterways navigated the boat to each asset.
The asset locations were defined geographically from the
rules. GT found the assets using a differential GPS. Each
asset was positioned to an accuracy of (±2m).
Under 3 months GT visited and mapped over 320 assets,
created 90 polygons of each of the zones (the shape which defines the area in which a rule has been enforced
e.g. a no boating zone or a speed restriction. A digital
photo of each asset was taken to compliment the GIS data
delivered. If an asset i.e. sign was missing no image was
taken and this information was recorded in the schedule
compliance.
GT delivered the data to MSV in Map Info format, to be
used for their GIS analysis of the waterways and to
develop stylistic and registration maps to increase public
awareness and a better understanding of the VOZR’s.
The pilot project was successful due to a Feasibility report
prepared by GT earlier which defined a well structured
data format specifying the data MSV required and GT’s
AIMS system sets no limits in spatially representing the
data to show what there is and what there should be.
Audit reports were created in addition to the data
delivered and put together by both GT and MSV to
facilitate the process of fixing anomalies/errors between
the VOZR and the actual locations of signage. Each Audit
report will be delivered to the appropriate Waterway
manager so that they can clearly see what is wrong from
all the information supplied i.e. maps, data, photos,
recommendations and know how to fix it.
