Geomatic Technologies completes Integral Energy Track Mapping Pilot Project
NSW, Australia 2007 – Geomatic
Technologies (GT), has successfully
completed a pilot data capture project, on
behalf of Integral Energy.
Project Brief – In 2007 Integral Energy
determined that improved corridor access
information was required for the
satisfactory management of incidents that
occurred within the transmission corridor.
Integral Energy engaged GT to conduct a
pilot data capture survey of access tracks.
GT was required to map the most
accessible route to the transmission
towers, incorporating the location of each
pole/tower.
Project Solution – A single 4-WD
mapping vehicle was configured with the
GT AIMS hardware (computers,
differential GPS, OH&S fit-out) and
software. Integral Energy supplied GT with
an extract from their GIS that contained
the transmission corridor centrelines, the
NSW public road network, high resolution
aerial imagery and power assets i.e.
conductors, substations.
The Integral Energy mapping specification
included detailed definitions of track
restrictions such as track conditions,
vegetation growth, gate types and gate
width measurements which were imparted
to the GT project team over a 2-day
training and observation period.
GT coordinated the Access tracks using
differential GPS as the mapping vehicle
transited their length after leaving the
public road network.
Each track was represented by a series of
nodes supplied at a 5m interval with
relevant features snapped to the track
polyline such that track topology and
relationship to the public road network was
maintained (essentially the data supplied
by GT could be used in routable
navigation dataset).
The GT team visited and mapped all high
voltage poles and towers in the specified
region and digital photos were taken of
gates and track obstructions, to
complement the GIS data delivered.
GT delivered a series of hardcopy map
books to Integral Energy, to assist
their field crews in locating assets via the
most direct route. All data was supplied to
Integral Energy in Map Info format for
subsequent loading into their enterprise
GIS system. The pilot project was
successful due to the systems and
procedures in place and the
professionalism and can-do attitude of the
GT staff. GT was awarded the task of
extending the work to encompass a further
five depot regions, this project is to be
completed by late January 2008.
