  1. 1. Wisdom-volkano : a novel tool based on open GIS and time-series to analyse and share volcanic data

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Fulgencio Sanmartín; [2016]
    Keywords : volcanic eruption; GIS; interferogram; time-series; seismology; GNSS; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Abstract : Active volcanoes threaten life around. In order to predict their eruptions earlier and mitigate their hazards, several variables must be observed and compared. Geographical information systems (GIS) combine different geospatial images from remote or local sensing. However, GIS often miss how maps change during the time. READ MORE

  2. 2. Developing a web-based system to visualize vegetation trends by a nonlinear regression algorithm

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Yufei Wei; [2016]
    Keywords : nonlinear regression algorithm; PolyTrend; vegetation trends; Physical Geography and Ecosystem Analysis; NDVI; Web Development; Django; MATLAB; Python; Earth and Environmental Sciences;

    Abstract : Comparing with traditional linear regression methods that used to monitor vegetation trends, a nonlinear regression algorithm (PolyTrend) developed by Jamali et al. (2014) can provide more accurate information of vegetation trends by fitting a polynomial line with a degree of up to three for ASCII-formed time-series NDVI (Normalized Difference Vegetation Index) dataset of a single pixel.
