  1. 1. Mapping forest habitats in protected areas by integrating LiDAR and SPOT Multispectral Data

    University essay from KTH/Geoinformatik

    Author : Manuela Alvarez; [2016]
    Keywords : LiDAR; spectral; spectral-LiDAR; SVM classification; forest classification;

    Abstract : KNAS (Continuous Habitat Mapping of Protected Areas) is a Metria AB project that produces vegetation and habitat mapping in protected areas in Sweden. Vegetation and habitat mapping is challenging due to its heterogeneity, spatial variability and complex vertical and horizontal structure. READ MORE

    Abstract : Ett första steg i arbetet att uppskatta kolflödet mellan landbaserade ekosystem och atmosfären är att så precist som möjligt analysera kvantiteten ovanjordisk biomassa. LiDAR teknologi har i detta avseende visat sig vara ett värdefullt verktyg. READ MORE

  5. 4. Change Detection in Stockholm between 1986 and 2006 using SPOT Multispectral and Panchromatic Data

    University essay from KTH/Geodesi och geoinformatik

    Author : Ann-Mari Skrifvare; [2013]
    Keywords : change detection; remote sensing;

    Abstract : With an increasing urban population in Sweden, expecting to reach 90% by 2050 (UN World Urbanization prospects, The 2011 Revision), this high level of urban population put pressure on functioning infrastructure, sufficient housing and need to monitor the environmental effects such as pollution and the effects of land use change. Stockholm County currently holds 22% of the population and accounts for nearly half of the urban growth in Sweden (Svensk Handelskammare). READ MORE

  6. 5. Mapping Lupinus nootkatensis in Iceland using SPOT 5 images
