As we have discussed in the last two issues of LP360 News, breaklines are two- or three-dimensional graphic data (points, lines, polygons) that we introduce into an elevation model to alter the topology. Surveyed mass points, scanned contour lines, correlated stereo models, and myriad other sources produce irregular elevation data that can be modeled as a TIN, and tools (such as LP360) that can manipulate random points are generally adept at processing these various data sources.

In the previous issue of LP360 News, I introduced the use of Triangulated Irregular Networks (TIN) for modeling point derived elevation data as well as the basic concepts of “soft” breaklines. I realized when writing that first article that it is probably a useful exercise to review contours. Thus this part II article will be devoted to this subject and we will continue with breaklines in the third article of the series. Read more...

As with any data, breaklines should undergo a QA/QC process. For breaklines this should entail a check for potential topology errors as well as incorrect elevation values. Read more...
