The Use of LiDAR in Digital Surface Modelling: Issues and Errors

122570989…from Transactions in GIS

“Modelling and extracting 3D geographical data presents numerous challenges that require continual research to attempt to evolve an efficient, reliable and accurate solution. LiDAR data capture and analysis has become a preferred acquisition choice for elevation data because the resulting quality and level of detail far exceeds traditional methods for large survey areas. As with any data collection system, LiDAR is prone to errors. Analysing these errors, ascertaining causes and producing error correction strategies is vital if accurate and confident results are to be obtained. Eight years of LiDAR datasets (from 1998 to 2005) have been closely analysed for a large coastal area of South Wales. This article provides a detailed and accurate summary of the identified LiDAR data issues and subsequent errors which affect the accuracy of end products such as Digital Surface Models (DSMs).”

  1. This article is something that we would be very pleased to look at as we used Lidar dataset last year only one occasion and we would be very pleased to know how a Lidar dataset can be utilized for different purposes.

    The only thing we did that we tried to figure out crest levels of flood defence embankments around the UK. Needless to say we needed to employ a pivot table option to find out what are those points that actually falls onto the embankment, but nevermind, we did our best.

    Anyway, the article sounds promising; in order to get full access you need to be registered by Wiley though. The registration is fairly straightforward though.
