…as their tool of choice for supplementing point cloud data (derived from LIDAR or correlated imagery) with breaklines. But what are breaklines and how should they be used? Over the…
…cloud data) for the Z value. Unlike the constant Z flat water body breaklines, we must store the Z for varying elevation breaklines at each vertex. This means that these…
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…
…assigning to the Z component of feature vertices. Contours: Before we delve in to exactly how breaklines are collected, it is useful to review contours and how they are generated…
…to constrain the generation of surface models. These introduced breaklines may be developed such that they do not modify the original surface geometry (“soft” breaklines) or to add “deflecting” elevation…
…software implementation. Even if you are not a user of our LP360 software, you will still gain a pretty good understanding of how breaklines are used to modify three-dimensional (3D)…
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…
…example) and those with the ability to store a different elevation value for each vertex (a down-stream flow polyline, for example). Breaklines, Part 5—Applying Breaklines to Enforce Varying Elevation …
…saves 1/3 of the storage. Why store a Z value at each polygon vertex when all Zs are the same? Breaklines, Part 4 – Applying Breaklines to Enforce Constant Elevation…
…we will continue with breaklines in the third article of the series. Before we delve in to hard breaklines, it is useful to review contours and how they are generated…
