Asia Air Survey Co., Ltd.
lidAr Beam of Hope
In the wake of the Great east Japan earthquake, Asia Air Survey conducted
liDAr mapping of the disaster area to provide data for damage assessment
and remediation. Using vehicle-mounted lasers with a 360-degree field of
view enabled the integration of imaging data and 3D position coordinates.
post-disaster 3D survey data was overlaid onto city planning maps to reveal the
scope of the disaster.
Asia Air Survey’s in-house topographic map production department used
microStation and DGn files as the basis of the maps. The liDAr trajectory was
created in DGn so the trajectory was shown for reference on the city planning
base maps. The 3D point clouds were read by microStation and displayed using
microStation’s point cloud visualization capabilities. The 360-degree surveying
was at least 10 times more efficient than stationary lasers.
located in the center of the netherlands, the city of Apeldoorn operates a
“virtual city” website to communicate with its citizens. The 3D presentations
engage users in the city planning process. To overcome the high cost of
converting design files into 3D format, the city set up a pilot workflow that
produces 3D content as part of the design process.

The city engaged Bentley in the pilot, which implemented Bentley map and
powercivil. The project team successfully integrated 3D file formats from
various disciplines and published the designs to the virtual city website. The
pilot prompted 50 percent of the city’s designers to produce 3D content for the
virtual city, eliminating the conversion process and producing 3D content for use
throughout a project lifecycle.
