Support for LAZ in TerraScan

Terrasolid now supports reading and writing of the compressed LAS file format LAZ in TerraScan, TerraMatch and TerraPhoto. Reduces file size 50% – 80% compared to LAS, usually 60-70% in most cases Excellent when you transfer data to someone else Support in the various products begins with the following versions: TerraScan and TerraScan Lite (v015.018)…

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…

Derive Grid to Ground Transformation with TerraScan

For certain projects, it may be necessary to process and output derivative products in a user defined (local) coordinate system. There are multiple ways to accomplish this, but one is to have matching pairs of projected and local coordinates to define a local coordinate system and derive the transformation. If the rotation, scale and translation…

TerraScan Display Mode Definitions and Descriptions

TerraScan provides users with many different methods of visualizing their point cloud data. These modes are based upon one or more attributes of the point data and each have their own uses. Some examples are herein provided. The Display Mode dialog (TerraScan -> View -> Display Mode) is how you access the current various modes.…

Tie Line-based matching for UAS data

The standard workflow for calibrating airborne laser data might not be well suited for laser data gathered using a small unmanned aerial system (UAS) due to the nature of how the data was collected and the inherent dynamic errors of the position and orientation systems typically used with these LIDAR systems. We have adapted the…

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…

Brush Classification Tool Cursor not Displaying

When using the TerraScan brush classification tool, the brush cursor is not displaying the outline. The common reason the brush cursor is not displaying is due to Accudraw being enabled. Accudraw can interfere with the normal operation of many Terrasolid tools. Toggle Accudraw off, by typing “Toggle Accudraw” in the search box in the top-right…

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,…
