The Technology Tracking the state of components at construction sites that are of an amorphous nature such as terrain is currently done by surveying. This can be costly and time-consuming. The emergence of scanning lasers has made real-time updates and earthwork calculations of the construction site a viable technique. The gathering of data is non-intrusive and will not impede the construction progress. The scanned data are imported using the import module.
Modules construct, regrid and rubbersheet are the primary modules.
Construct defines the mesh size and origin. Regrid maps the scattered points onto a grid. The module allows for the specification of the number of nearest points to the grid point to be used to calculate the average data value for that grid point. A radius may also be defined within which the nearest neighbors can be found. The volumes are computed by multiplying the projected are of the triangle by the average of the height of the prism and then summing up the volumes for all the prisms.
