   Sammanfattning : This report investigates the utilization of digital camera images (DCIs), sensitive in the visible part of the spectrum, for documentation of seasonal and inter-annual variations in snow cover and plant phenology. The DCIs used were transformed to orthographic images (ortho-image) from ordinary oblique DCIs taken between January 2001 and December 2003 at a sub- arctic mire (Stordalen) in northern Sweden.

3. 2. Multitemporala vegetationsstudier i nordöstra Kenya med AVHRR NDVI

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

   Författare :Camilla Jönsson; [1998]
   Nyckelord :geografi; naturgeografi; vegetationsstudier; nordöstra Kenya; AVHRR; NDVI; Earth and Environmental Sciences;

   Sammanfattning : In this paper coarse spatial resolution, high temporal frequency satellite data from the NOAA/AVHRR system are presented and analysed to demonstrate their utility for monitoring vegetation in a semiarid environment and for describing its seasonal dynamics. The study area consists of four districts in the North East of Kenya, namely Marsabit, Samburu, Mandera and Wajir. LÄS MER
