A recent USGS addendum to the LIDAR Base Specification has stated that “User-defined entities will not be allowed for capturing specific geoid information in the WKT”. LP360 (v2015.1.76.15 through v2023.3.31.1) Note: LP360 v2024.1.30.0 and natively supports the USGS requirements for the VERT_CS. No modifications are necessary in these versions. For older versions, in order to…
As of MSCE Update 16, independent of the GeoCue or TerraScan versions, running either a DirectDrive or Process in TerraScan command in the LIDAR 1 CuePac of the GeoCue workflow management software will launch MicroStation CONNECT Edition and open the desired design file as per the settings, however, no project, working segment/project block, nor raster…
Relative vertical accuracy, or flight line offsets, or the swath-to-swath fit between flight lines or drive passes can be qualitatively assessed using dz images. Or quantitatively assessed by exporting and analyzing the values. The USGS LiDAR Base Specification has evolved over the years with some different recommendations for evaluating interswath (overlap) consistency, and there are…
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…
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…
In GeoCue, when populating another layer of working segments, generating LIDAR orthos, or LIDARgrammetry stereo pairs from a layer, where that source layer has been adjusted using TerraMatch after the population of those source working segments, one might notice some slivers of missing data that follow the boundaries of the source working segments. The “gap”…
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…
The GeoCue workflow management software has the ability to Export Geometry and attributes from entities on any layer to a shapefile. Users may configure which attributes of the entity export with the geometry by configuring the applicable attributes, attribute groups and entities in Environment Builder. For example, users often wish to create geometry from the…
There are times when a user will desire to edit their LAS files in a project outside of GeoCue and then read these altered files back in. If attributes have been altered or lost and the user wishes to give these LAS files their original attribute values within GeoCue, the user can reassign these attributes…
About this Document Welcome to the GeoCue Command Dispatch System Administrator’s Guide. This document supplements the GeoCue User Guide and contains advanced information for the GeoCue Command Dispatch System (CDS). This guide is aimed at advanced users of the Command Dispatch System. Note that most information in this guide is not required for routine dispatched…
