Two project are proposed presented. More or less the same metodology used (GPS /GIS)for two different purposes.
GPS-TRACKING OF RED DEER IN TELEMARK, NORWAY
The red deer population is growing rapidly in Telemark county, Southeast Norway. To increase our knowledge of animal movement GPS tracking was carried out. Animals were captured at a feeding station during winter. Seven adult hinds were immobilized with a mixture of xylazin, zolazepam and tiletamin in March 2000 and collared with GPS-Simplex™ from Televilt. The same immobilization procedure was carried out the following year and collars were removed February 2001. The above mentioned procedure was repeated in year 2001 to 2002 so the total number of animals traced is 14.
The GPS-collars fixed positions 5 times a day. Data were stored in the collar and down- loaded in ASCII format. The stored positions were retrieved and transferred to GIS Arc View with the additional Animal Movement extension.
Based on the GPS-positions pathways and grassing areas were determined in the GIS, and habitat analyses is carried out by use of remote sensing and GIS. Topography and vegetation is the landscape elements analyzed as key habitat elements.
Monitoring of physical activit in 6-year old children during outdoor school activity.
Physical fitness and physical environment stimulating physical activity is a matter of high concern in Norway. Traditionally racecars programs dealing with such topics are using questionnaires for data collection. In this project we have tested use of GPS connected to the children’s wrist, and heart rate monitors the children’s chest to measure the physical intensity and areas visited. This is a more quantitative way of data capture. The results are then downloaded from the instrument, stored in a database and presented and analyzed by use of GIS. As part of this project accuracy test of the GPS receivers are carried out to be able to give some guideline how to achieve the optimal accuracy by use of simple and cheap receivers.
