Have you ever clicked on the Display by Point Source button and only gotten a single source display when you know that there are multiple source points (usually flight lines) in your data? Remember that to display your source points you must first add them to your project by using the Symbology /Point Source tab…
With the newest release of LP360 (2014.1) we added shortcut functions for the Contour and Intensity buttons. Now, to easily get to the symbology adjustments for these features you can simply click the Contour or Intensity button while holding down the Ctrl key. These two buttons are located on the LP360 Toolbar. Prior to this…
Challenge Much of the Lake Michigan shoreline in Wisconsin has a coastal bluff varying in height from less than 20 feet to over 140 feet. These bluffs erode in a number of ways and at varying rates (Figure 1). Over 175 profiles of these bluffs were measured and analyzed for slope stability in the mid-1970s…
Problem The following warning message is displayed when attempting to set-up the floating license client:”Successfully completed setting up the floating license client but having trouble contacting the specified License Server. (24284) ERROR: TCP channel protocol violation: expecting preamble.” Solution The error concerning TCP Channel Protocol violation is likely occurring due to either: incompatible LP360 versions,…
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…
Challenge Hernando County Florida needed to create a 3-D model of the City of Brooksville and turned to the Southwest Florida Water Management District (SWFWMD) office for help in getting the estimated building heights. Solution Because of LIDAR’s 3-dimensional qualities it is the perfect data source to extract building elevation information. This point cloud characteristic…
Last month’s tool tip discussed using the Planar Point Filter to filter buildings from point cloud data. This month’s tool tip discusses building extraction, essentially the next step after creating a building filter. The Point Group Tracing and Squaring Point Cloud Task will allow you to further refine the point cloud data classified as building…
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…
As you read this, we are releasing LP360 2013.2, our second major release of LP360 for calendar year 2013 (yes, yes- I know it is 2014 already!). One of the main developments for this release has been extensive improvements to the Point Cloud Task (PCT) subsystem of LP360. The PCT system is a framework for…
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…
