Reprojecting Vector Features

For Reprojecting Vector Features, use the Add Files dialog and go to the Feature tab. There is a checkbox in the lower section of the dialog to Transform Feature Files to Map SRS (Figure 1). The user may need to create a new EVO project with the desired target coordinate reference system (CRS). Note: EVO does not currently support on-the-fly…

Modify the Scan Angle Filter

Note: The following options only apply to LP360 2020.1 or newer. The Live View Filter – Scan Angle tab settings allow the user to filter data based on Scan Angle, which is typically associated with airborne and mobile laser scanning systems. It is the angle that the laser pulse was emitted with respect to a…

Associate Images with Features

One of the features available in True View Evo and LP360, that came from adding image support for the True View 3DIS, is the ability to associate images with existing features in a feature file. Depending on file organization, images can be assigned to specific features and displayed when selected in Feature Analyst. This could…

DEM and breakline export for use in CAD software

When generating a DEM in LP360 / True View Evo for import into CAD software, there are a few nuances to consider. Unlike the commonly used LandXML CAD surface format, the DEM format will only enforce breaklines at the resolution of the generated raster. In order to properly enforce and display the breakline areas, you…

Opening ArcMap project errors

The user receives multiple error messages and has general functionality issues when opening an ArcMap project with the 32 bit LP360 extension enabled. Example error message could be: PCTasksContentsView::ConnectToTrans(): Map object is null. This issue is related to the user opening an existing project, that was saved with the point cloud tasks tab open. The…

Civil3D Import DEM Issues

Civil3D has known import DEM issues. The user may notice a systematic shift related to units or grid positioning mismatch when comparing the imported DEM to other data in Civil3D, such as the breaklines that were also generated in LP360/True View EVO as part of the . Note: Depending on the scenario, the user may…

Update LAS file pyramids

Under normal circumstances, LAS files only need have pyramids generated during initial import into LP360/True View Evo. However, there are times when the user must rebuild LAS file pyramids after performing specific LP360 tasks. This article will review the method used to update pyramids, as well as the known tasks which will precipitate the user…

Using a point grid based on a vertical feature for change detection

It may be desired to create a grid of points for a vertical feature, such as a wall in LP360 or True View Evo. This could be used to detect the change of a set of gridded points, that are static in Z, which could potentially shift planimetrically over time. The following outlined workflow will…

Recommended LAS file size

While LP360 can handle a practically unlimited amount of LIDAR data, individual LAS file sizes must be kept small. LP360 and True View Evo have a maximum recommended individual LAS file size to optimize performance and functionality of the software. If the size of any LAS file used exceeds a recommended size of 250 MB,…
