1
Regional Scale Forest Mapping with Medium Resolution Satellite Data Dmitry E. Aksenov Elena S. Esipova Natalia V. Kuksina Mikhail L. Karpachevsky
3
Minimum set of information includes: Forest cover Dominant tree species Age of the upper canopy Productivity / growing stock estimation
4
Options for the forest cover and tree species: Modis data (like UMD TreeCover) + official forest survey data (lesoustroistvo) Landsat TM/ETM+ classification IRS-P6 AWiFS classification
5
Example of Landsat ETM+
6
dark coniferous (spruce, fir) pine mixed deciduous – dark coniferous deciduous (birch, aspen) cleacuts fire scars...and its classification by tree species
7
IRS-P6 AWiFS
8
Retrospective data allow age classification ~2000 Landsat ETM+ GLCF ~1990 Landsat TM GLCF ~1980 Landsat MSS GLCF 2007 Landsat TM IRS-P6 AWiFS ScanEx <1980 clearcuts in Landsat MSS Change detection MSS-TM Change detection TM-ETM+ Change detection ETM+-AWiFS MSS classification
9
Landsat MSS (~1980)
10
Landsat TM (~1990)
11
Change detection MSS-TM
12
Landsat TM (~1990)
13
Landsat ETM+ (~2000)
14
Change TM-ETM+
15
Logging of 1980-2000
16
Productivity / growing stock is still a problem NDVI in combination with official data? Radar data for sparse forests? Landsat imagery classification in combination with ground data (kNN-method)?
18
Kirov Oblast Mapping (2004-2006) ~2000 Landsat ETM+ GLCF ~1990 Landsat TM GLCF ~1980 Landsat MSS GLCF 2007 Landsat TM IRS-P6 AWiFS ScanEx <1980 clearcuts in Landsat MSS Change detection MSS-TM Change detection TM-ETM+ Change detection ETM+-AWiFS MSS classification + Landsat ETM+ classification for tree species
19
European Russia Mapping (2006-2007) ~2000 Landsat ETM+ GLCF ~1990 Landsat TM GLCF ~1980 Landsat MSS GLCF 2006 Modis <1980 clearcuts in Landsat MSS Change detection MSS-TM Change detection TM-ETM+ Change detection Modis 2001-2006 MSS classification + UMD Treecover Forest of the USSR (1990) Modis classification (Bartalev et al.)
20
European Russia Mapping (plans for 2008) ~2000 Landsat ETM+ GLCF ~1990 Landsat TM GLCF ~1980 Landsat MSS GLCF 2007 Landsat TM IRS-P6 AWiFS ScanEx <1980 clearcuts in Landsat MSS Change detection MSS-TM Change detection TM-ETM+ Change detection ETM+-AWiFS MSS classification + IRS-P6 AWiFS classification for tree species
21
Logging sustainability Planting Natural reforestation clearcuts selective logging forest fires pest outbreaks Forest resources Economically unavailable forests: - remote areas; - low-productive stands; - environmental limitations; - protected areas
22
MSS-TM-ETM+ change detection Northern Kirov Oblast
23
Lamdsat MSS, ~1980
24
Landsat TM, ~1990
25
Landsat ETM+, ~2000
26
non-forest areas clearcuts 1990 – 2000 ther forest clearcuts 1980-1990
27
non-forest areas clearcuts 1980 – 2000 гг. other forest
28
non-forest lands clearcuts 1980 – 2000 other forest old coniferous
