The DJI Zenmuse L1 is an entry level system that integrates the Avia Livox LIDAR, IMU, and a 20MP mapping camera on a gimbal fitted to the DJI M300 RTK. When bundled with DJI Terra and GeoCue’s EVO software, it allows users to deliver quality data derived from non-complex environments. This video tutorial will walk…
LP360 has several very useful command line executable utilities that can be used to simplify different tasks or improve the efficiency of large batch processes when working with substantial amounts of data or repeating processes. LDExport was added to this utility catalog with 2017.1. It simplifies the export of LAS points and surfaces, for example…
To reproject a raster in LP360/TrueView Evo you will need to establish the source SRS if one does not already exist. Do this by right-clicking on the raster layer, selecting Properties, SRS tab, and the ellipsis in the top right of the dialog. The Select Coordinate System dialog will pop up where you can setup…
In the last section, 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 application is “water body flattening” such as lakes and ponds. In this final section we will consider the case of varying elevation along the breakline.…
This is the fourth edition of our series on breaklines in LP360. In this edition, we will have a look at how features are represented in LP360 as well as the tools available for collecting “flat” breaklines. Features: Features in LP360 are internally stored as files in Shape format. This is a binary standard developed…
Introduction to Part 3: In the last part of this series, we discussed in some detail how a Triangulated Irregular Network (TIN) can be constrained by features external to the point cloud model such as lines, points and polygons. In this month’s edition, we will look at contours and how LP360 can extract elevation information…
This article is a continuation of the discussion of breaklines in LP360 (the standalone version). In last month’s installment, we discussed the overall concept of data modeling, especially the Triangulated Irregular Network (TIN). In this installment, I will discuss the general concept of adding constraints in the form of breaklines to these models. In future…
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…
On January 11, 2018, Benjamin H. Houston, P.E., PMP, GISP presented a webinar with GeoCue Group, Inc. on mapping urban drainage with airborne LIDAR using LP360. Benjamin Houston has over 25 years of experience with mapping technologies, both from military applications, environmental conservation and public works. He is a licensed professional engineer in New York and…
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…
