  1. 1. BIM to GIS-based building model conversion in support of urban energy simulation

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Zeyao Zhang; [2018]
    Nyckelord :BIM; GIS; CityGML; Energy Assessment; Building Energy Modelling; GEM; Earth and Environmental Sciences;

    Sammanfattning : In the context of growing population and increasing greenhouse gas emissions, urban energy planning is becoming a topic of high concern. With the rapid pace of urban construction, it is claimed that 40% of America’s total energy consumption is accounted by the building sector. LÄS MER

  2. 2. Comparison of multi-temporal and multispectral Sentinel-2 and Unmanned Aerial Vehicle imagery for crop type mapping

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Stephania Zabala Ramos; [2017]
    Nyckelord :classification; Random Forest; precision agriculture; UAV; remote sensing; Micasense; GEM; Earth and Environmental Sciences;

    Sammanfattning : Precision Agriculture aims to maximize crop production and the efficiency of land use to meet the increased demand for food while minimizing environmental impact and economic cost of food production. Crop type maps are needed for Precision Agriculture applications and remote sensing techniques are an efficient way to produce this information. LÄS MER

  3. 3. Identification Methods of Sri Lankan Corundum in Comparison to Other Common Gemstones

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Axel Kilbo Pehrson; [2017]
    Nyckelord :identification; Sri Lanka; corundum; gemstones; identifikation; Sri Lanka; Korund; ädelstenar;

    Sammanfattning : Sri Lanka is one of the leading countries in export of high quality corundum (Al2O3) gemstones due to the Precambrian rocks geological background. Combined highgrade metamorphic silicates and carbonate rocks makes perfect conditions for crystallization of this mineral. LÄS MER

  4. 4. Monitoring trends of greenness and LULC (land use/land cover) change in Addis Ababa and its surrounding using MODIS time-series and LANDSAT Data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tesfaye Gebeyehu Admasu; [2017]
    Nyckelord :Time-series; MODIS; Addis Ababa; Physical Geography and Ecosystem Science; NDVI; Greenness; LULC; GEM; Earth and Environmental Sciences;

    Sammanfattning : NDVI(Normalized Difference Vegetation Index) was introduced in 1974. Despite its limitations, it has been under use for monitoring bio-physical and cultural landscapes from satellite. LÄS MER

  5. 5. Identifying potential critical transitions in a forest ecosystem using satellite data

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Krishna Lamsal; [2017]
    Nyckelord :early warning; critical transition; tipping point; EVI; time series; GEM; Earth and Environmental Sciences;

    Sammanfattning : Ecosystems can undergo changes that are slow and gradual, or an abrupt change - a sudden nonlinear dynamics that can bring catastrophic changes and ultimately leads to the change in the structure and functioning. Non-linear and discontinuous changes sometimes may cause the system to shift into another undesirable state, called ‘regime shifts’ or ‘critical transition’. LÄS MER
