ICD Asia Pacific
Advanced
technical
solutions for
scanning,
measuring and
modelling assets
and environment
ICD are brownfields engineering specialists
driving innovation in energy, resources and heavy
industry.
Our in-house Geospatial team conducts
cadastral, civil & construction surveys, 3D laser
scanning and drone inspection, both as part of
larger ICD projects, and as stand-alone projects.
Scan data can be integrated with CAD designs
for enhanced designs and forms a basis for VR
models.
Project overview
The reason for this presentation is to
encourage other surveyors to participate in
similar projects to produce positive outcomes
for people adversely affected by bush fires
and other natural disasters.
Any Surveyor, at any time, anywhere in the
world, after any natural disaster can repeat
this project and achieve the same results.

Project Achievements • Protection of sub-surface survey marks,
• Sharing the history of the cadastre with the
residents,
• Demonstrating the use of surveying equipment
old and new
• Discussing the hardships endured by the early
surveyors
• Engaging the fire affected residents in such a
way to get their minds away from the
destruction that surrounds them - providing a
distraction and some breathing space
• Listening to their stories and experiences, giving
where possible, providing encouragement
Project Achievements • Taking the GPS and an owner on an adventure to
find the rock mark,
• having a couple of covid safe BBQ’s whist
demonstrating survey equipment and techniques
used by surveyors over many generations,
• Providing survey specific reading material so the
residents can discover more about how their land
was measured & marked
• Placing and coordinating permanent survey marks to
AUSPOS requirements for inclusion in the state coordinate data base
• Preparing a 'plan of survey information only' showing
the relationship of all survey marks found and placed
• Allowing others to engage in the project through
their generosity by providing materials and resources.
Conclusion
Some of the owners and residents of Mt
Tomah, who were adversely affected by the
bush fire on 15th December, 2019 have re-
engaged with their land through their
involvement with surveying and the discovery
of the cadastral history of their properties.

LANDATA could provide a link within the
surveyors' portal as a resource for these type
of surveying projects - to provide an outline &
resources for surveyors wishing to engage in
similar projects. Surveyors And Natural Disasters
