Information regarding the tools available in LP360.
Prolog: I am writing a new whitepaper on model constraints in LP360 (any reference to LP360 where I do not add the term “for ArcGIS,” I am talking about the standalone version. This document is extracted and heavily revised from a series of articles that I wrote for the GeoCue Group Newsletter in 2013. The…
LP360 has a Point Cloud Task (PCT) that can reproject raster layers, create pyramids, and JPEG compress. The PCT is named Reproject Raster. When we reproject an existing orthophoto to a new coordinate system, or re-write to a different unit, the user can choose to output uncompressed, or JPEG compressed. If JPEG compression is selected, the user…
Problem: There are some situations that can cause there to be a mismatch between surface elevations between tiles. This can become apparent in the vicinity of waterbody breaklines where a tile covers the water but only overlaps with a single shoreline. In this scenario, the surface generation process cannot consider the influence of breaklines on…
Problem: While attempting to execute a conflate point cloud task the user receives an “Executing task(s) failed. (8690) Unexpected error in ILPBrkLineEnforcer:GetLayerName(). (17486)” COM Exception. Probable Resolution: The root cause of this error tends to be that one of the layers listed in the breakline enforcement is not valid. Either the file no longer exists…
LP360 has several command line executable style programs that assist with productivity for different tasks, particularly when working with large amounts of data or repeating processes. These executables may be run: Via an MS-DOS style batch scripts By configuring corresponding commands and checklist steps within the GeoCue workflow software to take advantage of the command…
Point Cloud Tasks What is a Point Cloud Task (PCT)? A function (Extract ground, Conflate Line) that operates on points and/or vectors. A task can be a filter and/or an extractor. A filter classifies or changes the classification values for points (e.g. classify ground). An extractor extracts information from the point cloud data into vector,…
As many of you who are involved in LIDAR breakline collection know, we added some very nice feature edit tools to the Standard level of LP360 (Windows standalone version). One of these tools, “Create Features from Selected Features” is a very handy utility tool. Its basic function is to collect features you have selected with…
There are many tools and keyboard shortcuts that exist within the LP360 product suite, including LP360 for ArcGIS, LP360 for Windows, LP360 for sUAS, and LP360 for GeoCue. Remembering all of them and where to find them may prove difficult, particularly for beginner or casual users. To help we’ve created tool guides that provide the…
With the release of LP360 v2017.1 we began recommending that users create their breaklines using LP360 instead of the previous recommendation of using the LP360 Sketch tool in LP360 for ArcGIS. One common question that has come up is how does one create a flat 2D feature and put the summarize Z results in the…
A recent USGS addendum to the LIDAR Base Specification has stated that “User-defined entities will not be allowed for capturing specific geoid information in the WKT”. LP360 (v2015.1.76.15 or later) In order to remove this information from the VERT_CS WKT being included in LP360 generated WKTs it is necessary to replace the following file(s): “C:\Program…
