PROJ Integration into LAStools

We are pleased to announce that PROJ has been integrated into LAStools, enhancing the capabilities of geodesic calculations, cartographic projections, and coordinate transformations in LAStools. PROJ is a generic coordinate transformation software that transforms geospatial coordinates from one coordinate reference system (CRS) to another, including cartographic projections as well as geodetic transformations. It is used […]

Redesign of LAStools error handling

Release note for version 240510: The redesign of the error handling may require customization of scripts using LAStools. Background: The reasons for error messages can be minor (e.g. a tool argument is not in the correct range). However, especially when working in batch mode, it is crucial that errors in the process are reliably detected

lascopy: redesign with expanded matching by coordinates,…

The lascopy tool is well-known for matching data from different LAS/LAZ files and copying attributes between the files. The matching key is expected to have an identical timestamp/return to match the data. The redesign of lascopy expands the matching and coping part of the tool: it can now match not only for identical GPS time

‘Malware alerts’ when starting LAStools or laslook on Windows

Sometimes Windows refuses to start a program. This may be caused by Windows‘ internal security mechanism or by external virus scanners installed by users to protect their computers against viruses, malware programs, serious damage or theft of data. The Microsoft Windows operating system tries to prevent programs from randomly starting that appear suspicious, (e.g., if

Manual and non-standard installation of LAStools and laslook

LAStools and laslook are best installed via the default installer. This blog entry shows additional installation options. The goal of all installation methods is to copy files from the installation media to the target location. It is always possible to complete this task through a manual copy or a batch script. LAStools file structure LAStools

Using multiple Z dimensions within LAS/LAZ files

In general, the z coordinate of a LiDAR point within a LAS/LAZ file contains the absolute z value of the coordinate system used. For some operations such as classification (lasclassify) or canope metrics (lascanope) it is mandatory to specify the “height above ground” as an additional value for the calculations. There have been several ways

Point cloud filtering by HSL and HSV color models

The LAStools filter module was already able to filter colors according to RGB values. However, it sometimes makes sense to filter not only for RGB, but also for hue, saturation, and brightness values. Therefore, the HSL and HSV color models are quite common. LAStools now support these color models in filtering points. These are the
