Boreal Forest Snow Damage Mapping Using Multi-Temporal Sentinel-1 Data

Area-based Snow Damage Classification of Forest Canopies Using Bi-temporal Lidar Data

Multitemporal LiDAR data provide means for mapping structural changes in forest canopies. We demonstrate the use of area-based estimation method for snow damage assessment. Change features of bi-temporal LiDAR point height distributions were used as predictors in combination with in situ training data. In the winter 2009−2010, snow damages occurred in Hyytiälä (62°N, 24°E), southern Finland. Sn...

Snow Cover Monitoring Using Multi-temporal Envisat/asar Data

ABSTRACT A method has been developed to apply multi-temporal Advanced Synthetic Aperture Radar (ENVISAT/ASAR, C-Band) images to snow cover monitoring and mapping in mountainous areas. A multi-temporal dataset that includes sequences of ascending and descending ASAR wide swath and beam mode IS2 scenes acquired over Switzerland was investigated. The images were geometrically corrected to remove r...

Characterizing boreal forest wildfire with multi-temporal Landsat and LIDAR data

Retrieval of Biomass in Boreal Forest from Multi-temporal ERS-1/2 Interferometry

It is well known that C-band repeat-pass InSAR coherence can more accurately predict boreal forest stem volume than microwave radar backscatter. In this paper two boreal forest areas have been studied, one in Finland and one in Sweden. In spite of the small number of forest stands (approximately 40 stands at each site with mean area of 7 ha and stem volume range of 350 m/ha and 550 m/ha) a divi...

Comparison of Stem Volume Retrieval Accuracy in Boreal Forest Using Multi-temporal Ers Coherence Images

The availability of multi-temporal ERS one-day coherence images and extensive in situ data from test sites located in Sweden, Finland and Siberia has allowed a first assessment on the consistency of stem volume retrieval at stand level within the boreal zone. The test sites are characterised by different forest structure and ground properties. The coherence data had baselines up to 374 m. The r...
