3D presentations

Data can be brought to life through two and three-dimensional renditions.

The precision laser scanning capability within Halcrow enables us to rapidly create an accurate, three-dimensional model of a structure or area that can, in turn, be integrated with other spatial data sets, or used to create presentation videos and flythroughs or two-dimensional drawings.

We animate flat maps to show changing data over time, such as population changes in an area, or measuring noise pollution over the course of a day. We also use two dimensions to compare data, such as rental values in an area by showing blocks at different heights.

3D mapping

	Data sources	US Census data, NYC base map
	Client objective	Visualize building massing in a neighborhood, display spatial variation of rental values in Manhattan, explore the relationship between surface and subsurface structure.
	Map outcome	Exciting images that convey complex clusters of data in a clear and novel manner.
	Client benefit	Imagery that could not be created in-house was included in reports and presentations with good effect.

Terrestrial laser scanning

	Data sources	Field data acquisition with hi-tech laser scanner, mounted on survey tripod or mobile platform
	Client objective	The architect of additions to the landmark Union Station, Toronto required as-built drawings of all trusses in the passenger platform. Laser scanning and processing was far less expensive than hand measuring each structural element.
	Model outcome	Accurate AutoCAD drawings of each truss elevation, and a 3-D point set that can be used for measurements anytime.
	Client benefit	Laser scanning captured the entire interior truss system, so that more drawings and measurements can be acquired without returning to the field.
