LAS File Analyst

About LAS File Analyst

LAS File Analyst (LFA) provides the user the user with tools for analyzing LAS files for compliance with industry standard American Society for Photogrammetry and Remote Sensing (ASPRS) specifications and an associated set of tools for repairing and editing those that are defective. LFA is invoked by right clicking on a LAS layer in the TOC and selecting it from the menu or by clicking the button on the LP360 Toolbar. The dialog displays all of the file header metadata available for the LAS files on the layer in sortable columns. This data is immediately accessible upon adding LAS data to a project. There are Window Centering and Fitting tools for LAS Files, as well as copying rows to the clipboard , and a Move/Copy button for copying certain files to a target folder. The Move/Copy button is helpful when a user wants to "quarantine" certain files by excluding them from the project. The LFA dialog is non-modal, so it may remain displayed even while performing unrelated actions in LP360.

In addition, LFA has three-way synchronization between the TOC LAS files tab, rows (files) selected in the LFA dialog itself, and LAS file boundaries selected in the map view.
