Whilst it’s possible to load LiDAR data in a grid format into lower editions, its only with the Designer edition that these can be edited. These grid models can be used to create sections and simple volumes.
Grids are held as an rectangular array rather than as a triangular mesh DTM. This is an efficient way to store mass data as only the nodal height needs to be stored. Tools are available for editing this these arrays including updating grids from ground surveys and stripping out unwanted points along bands of interest like rivers or roads. This edited data can then be re-exported in grid formats. Aerial photographs can be superimposed onto these grids as show here above right.
Height factoring takes bore hole information and models the profile of underlying strata to a ground profile. Trend surfaces can be generated from Listed points and used to predict levels elsewhere in a model. Surcharge and bulking factoring to models allow the prediction of settlements.
Building footprints floor levels may be governed by the existing ground, requiring a balancing of cut and fill. A tool calculates this level and also the batter intercepts for the cut/fill line.
Horizontal and Vertical Alignments can be designed and used to model pavements, pipelines and rail with I/O to and from MX GENIO, including Hz transitions and Vt parabolas.
Data from cant sticks and trolleys can be fed into an option for rail surveys reporting on overlaps, parallels, versines, offsets, cants etc.
Radial sections can be used in visibility analysis. A height of observer and target are provided and each section line coloured green for visible and red for hidden.
