Points Disappear when Rotating View

Points disappear when rotating view or zooming in when trying to display in MicroStation window utilizing Terrasolid tools/products. Typically, points disappear when rotating the view because the rotation point used is not centered on the project area. Particularly at the elevation of the laser data. Tentative snap an appropriate rotation location by clicking both left…

Affine Transform LAS PCT

The Affine Transform LAS Point Cloud Task is a versatile tool for modifying the coordinates of your point cloud. A common use is applying grid to ground conversions which require more than a simple scale or translation. How to setup the Affine Transform LAS Point Cloud Task to accomplish this may not be readily apparent…

Apply a Horizontal Rotation about an Origin Point

This post applies if your grid to ground conversion requires needing to apply a horizontal rotation about an origin point and is defined by: Horizontal Translation North (tN) Horizontal Translation East (tE) Horizontal Rotation (Rz) Horizontal Origin Northing (N0) Horizontal Origin Easting (E0) Horizontal Scale Factor Then, if the horizontal scale factor is one, luckily,…

Applying a Horizontal Scale about an Origin Point

This post applies if your grid to ground conversion requires applying a horizontal scale about an origin point and is defined by: Horizontal Origin Northing (N0) Horizontal Origin Easting (E0) Horizontal Scale Factor Scale based grid to ground transformations are probably the most common. If the origin point is not defined, it is usually implied…

Combine Rotation Angles in TerraMatch

When using TerraMatch to Find Tie Line Match for whole dataset or line groups for heading, roll and/or pitch shifts TerraMatch determines correction angles. Users often wish to combine these with the original angles used in the LIDAR sensor manufacturer’s software so as to incorporate those corrections when generating additional data from the same sensor.…

Z Bump – Debias Operation Validity Testing

A common practice amongst GeoCue customers (and internally) is to use previously established control points to compare with an sUAS produced point cloud to gather absolute accuracy statistics. The vertical mean error from these statistics is often used to “Debias” a dataset. This is simply shifting the point cloud data to match the measured control…
