  1. 11. Relationship between tree species composition and phenology extracted from satellite data in Swedish forests

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Stefan Arvidsson; [2015]
    Keywords : MODIS; forests mapping; fractional mapping; satellite derived phenology; GIS; Physical Geography and Ecosystem analysis; TIMESAT; NDVI; EVI; Earth and Environmental Sciences;

    Abstract : This study investigated the “relationship between tree species composition and phenology extracted from satellite data in Swedish forests”. The proposed method investigated in this study aims at mapping the fractional composition of deciduous/coniferous tree species and also the fractional composition of Norway spruce (Picea abies) and several pine (Pinus sp.

  3. 12. Focal Operations with Network Distance Based Neighbourhoods : Implementation, Application and Visualization

    University essay from KTH/Geoinformatik

    Author : Nore Ottenby; [2015]
    Keywords : GIS; Map algebra; Focal sum; Focal Proximity; Network Analysis; Network Space; Location Problem; City Planning; Arcpy; Density map; Hotspot map;

    Abstract : In spatial analysis, many operations are performed considering the neighbouring locations of a feature. The standard definition of a neighbourhood is an area confined by geometrical length and direction with respect to its focus. When allocating a location for a service, the population distribution is often considered. READ MORE

  4. 13. Interactive visualization of financial data : Development of a visual data mining tool

    University essay from Institutionen för informationsteknologi

    Author : Joakim Saltin; [2012]
    Keywords : visual data mining; visualization; data warehousing; software engineering; materialized views; OLAP; OLAP cubes; greedy algorithm; high-performance query;

    Abstract : In this project, a prototype visual data mining tool was developed, allowing users to interactively investigate large multi-dimensional datasets visually (using 2D visualization techniques) using so called drill-down, roll-up and slicing operations. The project included all steps of the development, from writing specifications and designing the program to implementing and evaluating it. READ MORE

  5. 14. Real-time rendering of very large 3D scenes using hierarchical mesh simplification

    University essay from Institutionen för teknik och naturvetenskap

    Author : Daniel Jönsson; [2009]
    Keywords : terrain rendering; mesh decimation; mesh simplification; out-of-core; atmosphere rendering; large dataset visualization;

    Abstract : Captured and generated 3D data can be so large that it creates a problem for today's computers since they do not fit into the main or graphics card memory. Therefore methods for handling and rendering the data must be developed. This thesis presents a way to pre-process and render out-of-core height map data for real time use. READ MORE

  6. 15. Interactive Visualization Of Large Scale Time-Varying Datasets

    University essay from Institutionen för teknik och naturvetenskap

    Author : Willem Jan Frishert; [2008]
    Keywords : Large Scale Time-Varying Data; Direct Volume Rendering; Scientific Visualization; Real-Time Rendering;

    Abstract : Visualization of large scale time-varying volumetric datasets is an active topic of research. Technical limitations in terms of bandwidth and memory usage become a problem when visualizing these datasets on commodity computers at interactive frame rates. READ MORE
