LP360/True View EVO Rosetta Stone

Author: Lewis Graham, July 13, 2020

We were recently holding a strategy session regarding the development plans for our core point cloud processing tool collection, LP360®. I thought it would be worth sharing with you, our current and future customers.

LP360

LP360 is a comprehensive collection of visualization, processing, modeling and quality assessment tools for point clouds, both conventional and the colorized clouds generated by our True View® 3DIS™ drone systems.  It exists as two fundamental programs:

  • A legacy 32 bit application that is a fully qualified extension for ESRI’s ArcGIS product. We refer to this version as “LP360 for ArcGIS.” 
  • A native 64 bit Windows application with no platform prerequisites

LP360 for ArcGIS – This is our legacy 32 bit extension to ArcMap.  As development rolls along, a subset of new LP360 features are added to this extension but not all.  We are supporting ArcMap 10.1 and later versions.  LP360 for ArcGIS is available in three licensing levels:

  • Basic
  • Standard
  • Advanced

We have not yet embarked on a version for ArcGIS Pro.  LP360 is an “on the metal” product, meaning it makes low level system calls to graphics hardware to optimize display performance.  Avenues for programming at this level exist in ArcGIS, but not yet in Pro.  When (if) ESRI adds low level application programmer interface (API) support to Pro, we will look to porting LP360. Right now, we think you are better served by running the 64 bit (standalone) version of LP360. The performance gains as compared to using LAS Data Sets in ArcGIS Pro are significant. 

LP360 (sometimes called “Standalone” or “for Windows”) is our mainstream 64 bit application and the repository for all new LP360 (and True View EVO) features.  It has no software prerequisites.  It runs on Windows 10 only (we no longer support XP or 7 and we never supported 8).  The licensing levels are:

  • Viewer (free) – Visualization of point clouds and imagery. Rich display options that allow visualization of all LAS attributes in Map (plan), Profile and 3D views.
  • Basic – Adds QC annotation tools, application of imported model constraints (“breaklines”) as well as the ability to export derived products such as contours and point cloud derived digital elevation models.
  • Standard – Adds interactive data classification, point cloud-based feature extraction and creation of a variety of types of model constraints (“breaklines”)
  • Advanced – Adds a number of automatic feature extraction (AFE) algorithms such as automatic ground classification, extraction of planar surfaces (e.g. building footprints), rail extraction and so forth.
  • sUAS – Equivalent to Advanced, but limits the point cloud (LAS) area to 4 km2 or less.

LP360 Constraints Tool Example

An example of the power of LP360 is shown in Figure 1.  The blue polygon represents a water body in a dam data set collected with a True View 410 as part of a USDA R&D project we are conducting.  The contour rendering system is being constrained by a “water body flattening” rule applied to the polygon.  Notice there are no contours (magenta lines) crossing the boundary of the polygon.  Compare this to the other water bodies where a constraint is not applied.  In those areas, contours freely cross the water boundary.  We know this unconstrained model is not correct since still water is flat.  Exporting a DEM while applying breakline constraints ensures the DEM follows the applied topological rules.  This is an example of the very powerful modeling tools available in LP360 that are a fundamental requirement in many data production scenarios.

True View EVO is GeoCue’s post-processing environment for processing data from True View sensors (and soon selected “guest” sensors such as the DJI Phantom 4 RTK). It takes the LP360 software core and adds True View unique processing tools.  It is licensed as:

  • EVO Explorer (free but not yet released) –  This is essentially LP360 Viewer but includes the ability to use True View specific elements such as photos.  The idea is that our True View sensor customers will be able to build a data delivery package for their customers that includes EVO Explorer.  This would allow their customer to see the project as a standard True View project and do things such as click on a LIDAR point and see all images that are “seeing” that point and so on. 
  • EVO Lite – this is for processing GNSS systems only (no IMU).  Examples are the upcoming True View 210 and True View 250.  It will also support select ‘guest” sensors.  In fact, the first product Lite will support will be the Phantom 4 RTK.  Lite uses RTKlib for local base station processing in PPK mode (similar to our ASPSuite product for Loki direct geopositioning systems).  It will allow processing using Smart Base and PP RTX by consuming True View Points. 
  • EVO – same as LP360 Advanced but includes the True View sensor tool bar. It is limited to LAS areas less than or equal to 4 km2.  Hence it is equivalent to LP360 (sUAS) with the addition of all of the True View processing tools.
  • EVO Unlimited – removes the 4 km2 size limit

I have no doubt that LP360 is the most powerful and useful general purpose analytic tool set on the market for point cloud exploitation.  It is one of the most heavily funded R&D projects in our company.  Customers who have maintenance on LP360/EVO see a continuous stream of new tools added to the product on a regular basis.  If you are not yet using LP360, give it a try!
