GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.
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,…
Final products can be exported from LIDAR data using either LP360 command line executables or the LP360 Export Wizard. Some export functions and resulting products include, but are not limited to: merging multiple LAS files into one LAS file, exporting LAS versions to different LAS versions, exporting from LAS to ASCII XYZ files, and exporting…
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…
You can do part of a synoptic QA/QC on LIDAR data using either LP360 command line executables or the Point Cloud Statistics Extractor, which is one of the Point Cloud Tasks found within the LP360 GUI. Some general QA/QC information that can be gathered includes, but is not limited to, projection information, GPS time format,…
Now available in the experimental release of LP360 are the Display by Point Density / Export Density features. These features let you visualize your data color-coded by the number of points per unit area (point density). The Display by Point Density method lets you visualize the point density in real time within your project, whereas…
LIDAR data oftentimes requires preparation before further analysis can be completed on the data. LP360 has six command line executables which can be used for preparing LIDAR data before adding it to LP360 for Windows or the LP360 for ArcGIS extension. When installed in the default folder, these preparatory LP360 command line executables may be…
In the last edition of LP360 News, we discussed the creation of 3D breaklines for enforcing situations where the elevation must be a constant along the breakline. The most common example of this applications is “water body flattening” such as lakes and ponds. In this final installment of the breakline series, we will consider the…
In the last edition of LP360 News, we discussed the creation of 3D breaklines. Recall that, for our purposes, a 3D breakline is a vector that has an elevation value (Z) associated with each vertex. Generally, 3D breaklines can be divided into two categories – those with the same elevation for each vertex (used for…
KBA-01016-N3H6G5 Problem When I turn on the Breakline Enforcement in the LAS properties, choosing ‘shape’ as the elevation field (because my ponds and lakes have different elevations) and apply the settings, the water surfaces in the displayed TIN aren’t smooth and look just like without the breakline enforcement. Solution A couple of things to look…
