  • Multiangular remote sensing data
  • Subarctic areas

 

Research

I have graduated in January 2003 from the University of Turku and started my PhD studies in May 2003. I have four year position as graduate student in geoinformatics.

The working title of my PhD thesis is "Application of multiangular remote sensing data for land cover mapping and monitoring in tundra–taiga transition zone". The project aims to examine the potential of the multiangular observations to improve the accuracy of forest biophysical and inventory variables. The study area is located in northernmost Finland. The satellite data includes medium to coarse spatial resolution MISR (http://www-misr.jpl.nasa.gov/) and MODIS (http://modis.gsfc.nasa.gov/) data, but also high resolution ASTER (http://asterweb.jpl.nasa.gov/) data. The reference data consist of field measurements and biotope and forest inventory data. The methods include the statistical estimation of forest variables, accuracy assessment of existing land cover products and sensitivity analysis using canopy reflectance models.

My other research interests include remote sensing of boreal forest biomass and phenological monitoring of forest vegetation.

My previous research includes the work as a research assistant in the OMEGA project (http://omega.utu.fi) in the University of Turku in 2001–2003.
