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…
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 Pennsylvania State University Student Project by Travis Meyer Introduction Mangroves fulfill an important niche in wetland ecology and play a significant role in modifying the global carbon budget. They harbor and provide shelter for the offspring of many species of water birds, fish, and reptiles, and sequester close to five times the amount…
LP360 now has a full set of feature analysis and editing tools for working with the geometries of features – points, lines and polygons – in your project[1]. As often happens with LP360 features, the initial driver for adding this capability was a very specific problem; editing the toes of stockpiles being used in volume…
The density of point clouds (usually expressed as points per square meter) is increasing on what seems to be a monthly basis. This is particularly true of point clouds derived from Dense Image Matching (DIM), the clouds produced from software such as PhotoScan, Pix4D, DroneDeploy and so forth. You can quickly check the density of…
A Case Study from Philips’ Soil Challenge We conduct a core product inventory every quarter for our bark and pumice stockpiles to keep our bookkeeping updated. Our inventory collection methods consisted of simply guessing the volume of each pile (highly inaccurate) or having our loader operator move 5 yards of product at a time (extremely…
