LP360 Rail Extraction Tools for LIDAR
The LP360 Rail Extraction tools for LIDAR data automatically extract a rail alignment (centerline) vector as well as classify “top of rail”. This feature is implemented as a semi-automated Point Cloud Task (PCT) and is available in the Advanced version of both LP360 for ArcGIS® and LP360 for Windows® (the standalone version of LP360). We recommend…
Automatic Building Classification
So you have received LIDAR data and you really need to classify all those buildings in a timely fashion. The LP360 Planar Point Filter is an automatic process for classifying planar surfaces such as buildings. Located in the Point Cloud Task tab of the Table of Contents window of LP360, you can quickly set up…
LP360 2014.1 to Release in July
We will be releasing the first major version of LP360 for calendar year 2014 in July.

Using Base Maps in ArcGIS
Did you know that Base Maps are available in ArcMap 10.1 and 10.2? You can use this feature to display a backdrop image or road map, providing context for LIDAR data processing (see Figure 1). This is a coal pile area at the Tennessee Valley Authorities’ (TVA) Widows Creek fossil fuel generation facility near Stevenson,…
Classification Point Filter Shortcuts
The Classification Point Filter is used often throughout LP360 as part of the set-up routine for many different tasks. For example, many of the Point Cloud Tasks (PCT) require you to use this filter to select the classification source points that are either included or excluded when setting up and executing a PCT task. Classification…

LP360 for ArcGIS contains a set of tools which only appear…
Breaklines, Part 3 – Z Conflation
As we have discussed in the last two issues of LP360 News, breaklines are two- or three-dimensional graphic data (points, lines, polygons) that we introduce into an elevation model to alter the topology. When working with Geographical Information System (GIS) models, we nearly always model complex, irregular elevation data as a Triangulated Irregular Network (TIN).…
