… ecological services associated with new housing estate. The thesis aims, with remote sensing and field studies as methods, to investigate whether it is possible to turn focus from using BAF as a planning tool when building new habitations and instead to use it as an analysis …
… on two totally different applications, facial expressions recognition and remote sensing. The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These …
… water might be strongly correlated to the concentration of dissolved nitrogen. Remote sensing, statistics and GIS were used as valuable tools for gathering, analyzing and handling large amounts of spatial information with high accuracy and integration.
en förändringsstudie av småvatten i Skåne och deras kväveretentionsförmåga
… over Scania were randomly chosen and systematically scanned for wetlands using remote sensing. The wetlands were then onscreen digitalized in a GIS. Area and numbers were then analyzed along with some spatial features important for nitrogen retention, such as location in the …
The purpose of this study is to investigate how to use remote sensing data when making a forest management plan. The main focus of the study is to compare different methods to identify forest stands of a forest property, and by manual measures and estimates try to evaluate the …
en förstudie
En förutsättning för skoglig planering på alla nivåer är att man har en god uppfattning om tillståndet i den stående skogen. K valiten på de beslut som fattas kommer därför att vara direkt beroende av mängden och kvaliten på den information som samlats in. Sensorer som radar …
Populärvetenskaplig sammanfattning: Det var torkan under åren 1968 - 1973 som fokuserade världens uppmärksamhet till Sahelregionen, som är ett smalt bälte mellan Saharaöknen i norra Afrika och grässlätterna söder därom. De ovanligt torra åren hade lett till matbrist i form av …
Several studies have analysed the relationship between Normalised Difference Vegetation Index (NDVI) and radiative surface temperature. A main goal for most studies have been to find the best method for carrying out land cover classifications and to study land cover changes …
The Multispectral Canopy Reflectance Model (MCRM) by Kuusk (1995) has been used to simulate the reflectance of a sugarbeet canopy. The simulated reflectance values show high absorptance in the VIS area, compared to field measurements, and high reflectance values in the NIR area …
jämförelse mellan 1940, 1980 och 2000-talet
Populärvetenskaplig sammanfattning: Småvatten i form av dammar och våtmarker har en viktig funktion i både den terrestra och akvatiska miljön. De fungerar till exempel som buffert för näringsämnen från att flöda ut i havet och dem ökar den biologiska mångfalden bland växter och …
Populärvetenskaplig sammanfattning: Kan satellitbilder användas för att studera skador på bok och ek? Sedan mitten av 1970-talet har man sett ökande skador på skogen i stora delar av Europa. Olika storlek på skadorna och att storleken på skadorna skiljer sig åt beroende på var …
en metodstudie
… it was possible to classify the fire effects on the tree stands using remote sensing. A test of was performed with three experienced interpreters of aerial photography, using the field data as reference material. The results show that the method gives a high accuracy in …
… new inventory techniques to get the important forest data. The company Foran Remote Sensing offers the opportunity with airborne laserscanning of forest and forest land. Foran got the mission of Bergvik and StoraEnso to laser scan Bergviks possession in Älvdalen, Dalarna …
This study presents results for observing forest changes in Sweden using multi-temporal L-band satellite data and is a part of the JAXA’s ALOS Kyoto and Carbon Initiative. An extensive dataset of images acquired by the Advanced Land Observing Satellite Phased Array type L-band …
beräkningar med massaslutenhet
This master’s thesis is a remote sensing study of an area-based method used to detect forest in need of thinning by use of laser data and field samples. Only pine-dominated forest has been included in the study and height limits were set to match empirical restrictions. The …
