Executables Used by LP360 or True View EVO

If your organization has strict security settings, some of the executables installed and used by LP360 or True View EVO could get blocked and prevent LP360/EVO from operating correctly.  It may be necessary to get your IT department to add these executables to an approved list.  The following instructions will show you how to find…

Multipart Features and the Feature Edit Tools

Multipart features are not supported for the Feature Edit tools in LP360 standalone and may result in an error message such as, “…Complex polygons is not supported”. You will need to first Disassemble Multipart Feature, then run the Split Geometry, Double Line Drain or other such Feature Edit tool.  You can then assemble the parts back into…

LDExport – An LP360 Command Line Executable

LP360 has several very useful command line executable utilities that can be used to simplify different tasks or improve the efficiency of large batch processes when working with substantial amounts of data or repeating processes.  LDExport was added to this utility catalog with 2017.1.  It simplifies the export of LAS points and surfaces, for example…

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…

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,…

Applying a Horizontal Scale about an Origin Point

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…

Create Seawall Feature from Point Cloud

The Create Seawall Feature tool, found on the LP360 feature edit toolbar, allows the user to create a contiguous polygon feature at the proper width/depth and height of a seawall (or any similar feature) contained in the point cloud. This function can be scaled to fit the specific scenario of the user: from simple walls…

Drawing Map Complete, but no WMS displayed when using RDP

When connect to a machine using RDP, adding a WMS backdrop to LP360 or True View EVO results in the message, “Drawing Map Complete” showing in the lower left-hand corner, but no image is displayed for the WMS layer. LP360 and True View EVO use OpenGL and Microsoft’s Remote Desktop only uses software OpenGL by…

Z Bump – Debias Operation Validity Testing

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…

Proximity Classifier Point Cloud Task

The Proximity Classifier Point Cloud Task found in LP360 and True View EVO classifies points based on attributes of a proximal point. A couple of use case scenarios could be: Classifying a new dataset based on an older one for datasets from multiple collect times. Classifying a subset of a larger dataset, then incorporating the…
