  1. 1. Forest stand delineation through remote sensing and Object-Based Image Analysis

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : José Antonio Ortega-García; [2018]
    Keywords : forest stand; stand delineation; LiDAR; ASTER; OBIA; GIS; remote sensing; segmentation; canopy heigh model; forestry; Navarra; OBIA; LiDAR; ASTER; segmentación; rodal; forestal; SIG; teledetección;

    Abstract : Forest stand delineation is an essential task of forest management planning which can be time consuming and exposed to subjectivity. The increasing availability of LiDAR data and multispectral imagery offers an opportunity to improve stand delineation by means of remotely-sensed data. READ MORE

  3. 2. Effects of data uncertainty on dynamic treatment units

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Artis Becs; [2018]
    Keywords : DTU; dynamic treatment units; airborne laser scanning; ALS; tactical planning; final felling; RMSE; relative mean square error; segmentation;

    Abstract : The purpose of this thesis was to study the effects of uncertainty in the pixel level estimates concerning the potential benefits of dynamic, pixel-based treatment units compared to traditional stand-based treatment allocation. Because of automatic stand delineation having benefits resulting in the possibility to be more commonly used in forest industry. READ MORE

  4. 3. Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter

    University essay from SLU/Dept. of Forest Resource Management

    Author : Adam Burström; [2014]
    Keywords : traktplanering; subjektiv inventering; intervjuer; Heureka; inoptimalförlust;

    Abstract : A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. READ MORE

  5. 4. Ajuourhållning av ungskogsdata med hjälp av digitala flygbilder

    University essay from SLU/Dept. of Forest Resource Management

    Author : Henrik Johansson; [2008]
    Keywords : tolkning i digitala flygbilder; ajourhållning; bedömning av skogliga variabler i digitala flygbilder;

    Abstract : The purpose of this study is to investigate whether it is possible for SCA to update their stand register with use of digital aerial photos photographed with a Zeiss/Intergraph DMC. "Updating" in this study implies the delineation of stands and estimating stand variables such as average stand height, volume density, stand volume, and tree species composition in order to identify stands which can be of current interest for thinning.

  6. 5. Utvärdering av flygbildstolkning för uppskattning av beståndsvariabler och åtgärdsförslag i ungskogar : en studie på Korsnäs Skog och Bergvik Skog AB i västra Dalarna

    University essay from SLU/Dept. of Forest Resource Management

    Author : Lars Andersson; [2008]
    Keywords : beståndsdata; flygbildstolkning; gallring; inventering; röjning; åtgärdsförslag;

    Abstract : In Korsnäs district Dala Väst there were problems with information concerning their younger forests, mainly those in pre-thinning stage. They were divided into large, heterogeneous stands with often poor stand data quality. In 2006 an aerial photo interpretation of the young forests was conducted to fix these problems. READ MORE
