1 Galina N. Fet Image Processing for Conifer Forest Detection in Tien-Shan Mountains. Marshall University, Department of Physical Sciences Geobiophysical Modeling Graduate Program May 18, 2006

2 STUDY AREA Environmental Monitoring Natural Resources Exploration and Conservation International Tourism Development TIEN-SHAN MOUNTAINS, KYRGYZ REPUBLIC Google Earth

3 STUDY OBJECTIVES  imagery classification: vegetation and non-vegetation feature extraction  vegetation classification and mapping using ground data and imagery  species database compilation for Internet distribution

4 VEGETATION COMPLEXITY  Juniper or Spruce clear stands or mix FOREST => THAN 75 %  Dwarf Juniper and shrubs  Riparian mountain forests with Spruce  Grasslands and mountain meadows with Juniper or dwarf Juniper

5 FOREST TYPE GROUND CONTROL POINTS DATA AND SPECIES GEODATABASE DIGITAL ELEVATION MODEL SATELLITE IMAGERY AND ROCESSING SOFTWARE INCREASE QUALITY AND ACCURACY PRODUCE ELEVATION LAYER EXTRACT ELEVATION CONTOURS AND WATERSHEDS BAND COMBINATION ASESSMENT AND STATISTICS 3D VISUALIZATION SPATIAL STATISTICS AND SURFACE ANALYSIS IMAGE PROCESSING AND CLASSIFICATION STEPS AND COPONENTS PLANT ECOLOGY AND BOTANY

15 SUPERVISED CLASSIFICATION DIGITIZING CONTOURS SPECTRAL SIGNATURES

16 SUPERVISED CLASSIFICATION SPRUCE FOREST mixed with two different species of junupers (Juniperus turkestanica – dwarf juniper and Juniperus semiglobosa), SPRUCE-BIRCH forest with shrubs and other deciduous trees in the understory. DWARF JUNIFER SHRUBLIKE FOREST in association with numerous and diverse shrubs in the understory
