Abstract: There has been a great deal of interest in LiDAR recently, and the industry seems set on acquiring LiDAR data in the near future. Opportunities such as highly accurate ground mapping, tree heights, tree counts and maps showing within-stand variation in volume and basal area can add value individually, but in combination offer a huge benefit to foresters. With all the hype, forest managers could be forgiven for believing that for a dollar or two per hectare LiDAR could tell them everything they wish to know about their whole estate. In reality though, the expression ‘rubbish in rubbish out’ holds expensively true, and a reasonable amount of care and knowledge is needed to ensure that the forester gets a worthwhile return from his investment. Used appropriately LiDAR holds huge potential for New Zealand forestry, and this article explains how to reap the benefits of LiDAR whilst keeping realistic about its limitations.
