Forest species classification using Object Oriented Image Analysis does CIR aerial imagery and Object Oriented Methods offer new possibilities?

摘要

National Forest Inventories (NFI) in Britain such as the Forestry Commissions National Inventory of Woodlands and Trees (NIWT) and the Scottish Native Woodland Survey (SNWS) provide a synoptic view of the current extent, condition and location of forest resources. The NFIs not only need to be accurate and precise but also up-to-date. The methodology implemented in Britain relies on photo-interpretation analysis of digital aerial photographs combined with field-based methods. This methodology, besides its advantages, is perceived as cost-intensive.
