Webinar: Photogrammetry vs SfM vs Lidar
Date & Time

Modern surveyors are spoilt for choice – in addition to traditional surveying techniques, drones have dramatically lowered the cost of aerial acquisition and thereby massively reduced the project size required to make it viable. With the advent of lightweight Lidar systems even aerial laser scanning is now an option for relatively small jobs.
However, it is important to understand the characteristics of each technology beyond what’s printed on a marketing brochure in order to make an informed choice on the technology to use and how to apply it.
For example, the processing times and accuracy obtained with modern photogrammetry and SfM packages can be extremely sensitive to the settings used and the algorithm chosen. Without a clear understanding of how they work, practitioners may be unaware of the trade-offs they are making and the impact that is having on the quality of the data generated as well as the time required to generate that data.
In this talk we will take a peek inside the black boxes to look at how they work and use real-world projects to illustrate the advantages and limitations of each option. Guidance will also be provided on the factors that influence which choice is the most appropriate in a range of different circumstances.
