GeoCue’s repository of articles covering tools, tips, and workflows for processing point clouds in LP360 Geospatial.
Quality control and assurance checks should be applicable for various acquisition scenarios so as to not limit the methods that a data provider may use to obtain usable data. In that regard, some providers use collection methods that require multiple overlapping swaths in order to adhere to the project requirements. In other cases, simple side…
A Conflation Task defines a set of procedures for digitizing features that extract elevations from a LIDAR surface. A conflation task can be configured to digitize points, polylines, and/or polygon features. The Conflation Method assigned to the conflation task defines how elevations are populated onto the geometry for each feature. LP360 Default Conflation Tasks Summarize Z…
LP360 always uses a scale of 0.001 when exporting LAS files so as never to degrade the precision of the data. There is no user option like there is in TerraScan or GeoCue to specify the desired resolution and the mechanism that allows LP360 to load “unlimited” LIDAR prevents it from knowing the precision of all of…
Versions of OpenGL Supported in LP360 and Topolyst 2016: Previous versions of LP360 supported OpenGL 1.0 only. OpenGL 1.0 was released on Windows in 1994. Both the LP360 standalone and Topolyst products now support two versions of OpenGL, OpenGL 4.4, or better if available, and OpenGL 1.1 are supported for these two products. The LP360 for…
The following workflow and accompanying video describes the suggested workflow for digitizing breaklines around islands within LP360. Creating Island Breaklines: Workflow Configure a conflation task for the lake or main waterbody that the island resides within. Set up a conflation method for the conflation task This is dependent upon user specifications, the example in the video chooses…
About Pyramiding Files Pyramiding is used to improve display performance for large files. This is similar to the way reduced resolution overviews work. When the Pyramid checkbox is selected, a pyramid file (.QVR) is created for any file that is either missing the .QVR file or the .QVR file is older than the file. For LAS…
Problem: On the License Server Info tab of the LP360 License Administrator one sees the error message “No connection could be made because the target machine actively refused it”. Probable Resolution #1: Is the LP360 License Server machine turned on? Probable Resolution #2: Can the client machine communicate with the LP360 license server machine? Option…
Introduced in LP360 v2015.1, Live View is a new source point filter for defining how points are visualized in real-time within the program and also used by various filters and Point Cloud Tasks throughout the program. The purpose of this article is to provide users with a more in-depth look into Live View and how…
Note: While the Arctoolbox tools are still an option within the product, the introduction of LAS File Analyst in v2018.1 and the ReProject/Shift LAS PCT in v2017.1, the new tools provide more efficient and robust tools and are now the recommended tools to use. Symptom: While installing the LP360 toolbox tools in the ArcToolbox an…
