The effect of continuous-cover forest management on Norway spruce stem taper revealed by terrestrial laser scanning
In the Nordic countries, rotational forestry (RF) is the dominant silvicultural practice. RF is associated with biodiversity and ecosystem losses and may compromise wood quality. Continuous cover forestry (CCF) has been proposed as an alternative or complementary practice to RF. In CCF, the stand succession cycle differs from RF, which influences the rate and rhythm of tree growth, including the allocation of growth resources along the length of …
A novel approach for bilberry yield mapping integrating airborne laser scanning, map databases, and automatically interpreted terrestrial images
Picking of wild berries is a common activity in the Nordic countries, but finding productive areas can be challenging, especially for inexperienced pickers. This article presents a novel approach for bilberry ( Vaccinium myrtillus ) yield mapping based on random forest (RF) classification. A large variety of features for classification was derived from airborne laser scanning (ALS) data and existing map databases. Training data were obtained by a…
Capturing trends in forest structural complexity development using laser scanning techniques
Forest structural complexity reflects realized niche occupancy, capturing how effectively the vegetation utilizes available resources and provides habitats for species. This makes it a key indicator of forest ecosystem diversity, and an important characteristic to be monitored to facilitate sustainable forest management and conservation planning. Laser scanning has been recognized as a feasible technology for the characterization of heterogeneity…
Concepts Towards Nation-Wide Individual Tree Data and Virtual Forests
Individual tree data could offer potential uses for both forestry and landscape visualization but has not yet been realized on a large scale. Relying on 5 points/m2 Finnish national laser scanning, we present the design and implementation of a system for producing, storing, distributing, querying, and viewing individual tree data, both in a web browser and in a game engine-mediated interactive 3D visualization, “virtual forest”. In our experiment…
Near Real-Time Semantic View Analysis of 3D City Models in Web Browser
3D city models and their browser-based applications have become an increasingly applied tool in the cities. One of their applications is the analysis views and visibility, applicable to property valuation and evaluation of urban green infrastructure. We present a near real-time semantic view analysis relying on a 3D city model, implemented in a web browser. The analysis is tested in two alternative use cases: property valuation and evaluation of …
Multisensorial Close-Range Sensing Generates Benefits for Characterization of Managed Scots Pine (Pinus sylvestris L.) Stands
Terrestrial laser scanning (TLS) provides a detailed three-dimensional representation of surrounding forest structures. However, due to close-range hemispherical scanning geometry, the ability of TLS technique to comprehensively characterize all trees, and especially upper parts of forest canopy, is often limited. In this study, we investigated how much forest characterization capacity can be improved in managed Scots pine (Pinus sylvestris L.) s…
