Satellite Remote Sensing in Archaeology: Imagery Analysis
- 1. Remote Sensing in Archaeology Imagery Analysis
- 2. Remote Sensing Perception at a distance Interpretation of imagery Spatial analysis
- 3. Archaeology Site detection Regional spatial analysis Predictive modeling Historic preservation in regional planning
- 4. Early Remotely Sensed Data French balloonist Reconnaissance photography USDA and USGS aerial data Landsat program
- 5. Multispectral Imagery Several to hundreds of 9 data layers 1 1 8 Layer 1 (8,9) 9 Stacked data file 1 1 8 Layer 2 (8,9) 9 Choose three to show 1 1 8 Layer 3 (8,9)
- 6. Multispectral Scanning Selected wavelengths Airborne and satellite Measurement of differences Electromagnetic radiation
- 7. Electromagnetic Radiation Light, heat, and microwaves Differential reflection/emmisivity
- 8. Shorter Wavelengths Reflectance Solar radiation Visible,NIR, and MIR
- 9. Longer Wave Lengths Thermal bands Emissivity Radar Geometric and dielectric properties
- 10. Key Targets for Wavelength Blue Soil, plants, buildings, roads, water Green Traces of buildings and roads, plant type boundaries Red Buildings, roads, chlorophyll absorption bands Near infrared Soil moisture, bodies of water Middle infrared Types of rock, Soil moisture Thermal infrared Heat, soil moisture, plant stress Microwave Objects buried in arid soils, cultural features
