Breaklines in LP360- Part 5

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.…

Breaklines in LP360- Part 4

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…

Breaklines in LP360- Part 3

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…

Breaklines in LP360- Part 2

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…

Creating a 2D Feature with Elevation Attributes

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…
