PolyWorks Introduces Huge Dataset Processing Methodology for Surveyors 12.21.04

InnovMetric Software announced that its flagship product PolyWorks now offers a new huge dataset import methodology to handle super-large datasets that cover thousands of square meters, which is standard in civil engineering applications. This unique feature will enable surveyors to handle datasets consisting of hundreds of millions of data points on standard 32-bit computers.

The PolyWorks methodology consists in managing the point clouds by using grid cells uniformly distributed along the XY plane. As all the points cannot be kept in physical memory simultaneously, incoming point cloud files are read scan by scan, and points are relocated into their respective cells and written back to disk. Once all points have been imported, users can access specific areas to perform measurements or feature extraction by enabling or disabling grid cells. To prevent physical memory exhaustion, PolyWorks offers a grid cell manager that indicates to users how much RAM they will use when they enable N grid cells.
