Basic LIDAR Breaklines in True View EVO
September 01, 2021

We find that traditional surveyors who transition to drone-based LIDAR systems are often concerned with how breaklines can be added to models in our EVO post-processing software. The good news is that True View EVO contains extensive tools for both adding and enforcing breaklines in topographical modeling

Using TerraMatch to Apply Strip Adjustments to LIDAR Data
July 29, 2021

TerraMatch uses the traditional approach to strip adjustment of identifying common tie lines and tie points in each LIDAR flight line and fitting these tie lines and tie points to minimize the dynamic errors between the lines and between separate lifts/flights.

True View EVO - The Only LIDAR Processing Tool You Need
July 08, 2021

One difficulty with unmannned aerial system (UAS) LIDAR and imaging sensors is the lack of good post-processing software. However, our hardware includes full post-processing software from the ingest of raw sensor data to finished or CAD-ready products! In this article we highlight the software tools that are available in True View EVO, illustrating why our True View solution offers the most comprehensive solution for UAS-based LIDAR/Imagery in the market.

Why LIDAR for Volumetrics?
June 18, 2021

In a previous issue, we took a detailed look at the volumetric analysis tools in True View EVO/LP360. In this issue, I want to take a step back and discuss why you would use a LIDAR system rather than photogrammetry for this type work.
