LP360: Breaklines, Part 4
October 29, 2018

This is the fourth edition of our series on breaklines in LP360, our advanced LIDAR and point cloud processing software. 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.

LP360: Breaklines Part 3
September 25, 2018

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, our advanced LIDAR and point cloud processing software, can extract elevation information from point cloud data for assigning to the Z component of feature vertices.

LP360: Breaklines Part 2
August 27, 2018

This article is a continuation of the discussion of breaklines in the standalone version of LP360, our advanced LIDAR and point cloud processing software. 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.

Recommended Number of Flight Lines for a Mapping Mission
August 22, 2018

Structure from Motion (SfM) algorithms used by image -to-point cloud applications require strong overlap to create an accurate 3D model. Missions should be planned to include both forward overlap, and side overlap.

Is Loki compatible with other Structure from Motion software aside from PhotoScan and Pix4D?
August 16, 2018

The answer to this question will depend on the Structure from Motion software being used. The two primary components are the ability to use high-accuracy geotags and the ability to incorporate a camera calibration based on Brown's Distortion Model.

Local Coordinate Systems in AirGon's ASP Suite
August 08, 2018

Many sites have large-scale projected systems defined just over the local site, which does not match existing national and state grids. We refer to these as local coordinate systems, and while local easting and northing image locations can be input to PhotoScan, Pix4D, etc., those applications do not support converting geographic coordinates to local projected coordinates. Learn how to use the new Local Coordinate System Manager tool in AirGon's ASPSuite.

LP360: Breaklines Part 1
July 24, 2018

This document is extracted and heavily revised from a series of articles that I wrote in 2013. The big change is that, at that time, we only had enforcement in the standalone version of LP360, which is our advanced LIDAR and point cloud processing software. Now, we are essentially feature-complete with new tools in standalone LP360. Not only are all of the breakline creation tools present, but we also have a very rich set of 3D feature edit tools.
