History

1858: First aerial pictures by French photographer and balloonist Nada over Paris, France.

1959: Explorer 6 takes first satellite image of earth.

1972: Birth of Landsat and birth of spaceborne MSI.

1972: Blue Marble from Apollo 17.

1977: KH-11 series satellites give first near real-time imagery.

2007: Worldview-1 has current lowest commercial GSD @ 0.5m for a satellite.


The Playing Field (μm)

Sample HSI

Sample MSI


Visible Wavelength Sensors


Houston, TX 10/07 via Worldview-1


Houston, TX 10/07 via Worldview-1


Utility of MSI

  • NDVI

  • Crop growth stage

  • Fire detection

  • Surface Temperature

  • Landcover usage (NLCD)

  • Deforestation monitoring

  • Mineral mapping

  • Soil Brightness Index (SBI)

  • Green Vegetation Index (GVI)


Multispectral Sensors


Land Cover Classification


MODIS Fire Map


MODIS NDVI


Landsat Program

  • Sats launched 1972-1999

  • 7 satellites (Landsat 6 failed to reach orbit)

  • Only 5 and 7 still functioning

  • Multispectral (MSS) on Landsat 1-5

  • Thematic Mapper (TM) sensor on Landsat 4 & 5

    • 0.45 um – 2.35um + thermal band (10.4-12.5)

  • Enhanced Thematic Mapper (ETM+) on Landsat 7

  • Landsat 1: 18 day revisit, RBV, MSS

  • Landsat 2: 18 day revisit, RBV, MSS

  • Landsat 3: 18 day revisit, RBV, MSS, first with thermal band

  • Landsat 4: 16 day revisit, TM, MSS, 30m max resolution

  • Landsat 5: TM, MSS, 16 day revisit, provide global archive of satellite photos, TM

  • Landsat 7 (ETM+, 16 day revisit, 15m resolution panchromatic, 60m thermal resolution, Current, cloud free imagery)

    • ETM+ has 8 bands including thermal


Utility of HSI

  • Material abundance maps (MAMs)

  • Subpixel detection

  • Automatic target recognition (ATR)

  • Crop health

  • Crop type


Hyperspectral Sensors


Mineral Maps of Cuprite, NV


MAM from Moffett Field, CA


Utility of SAR

  • Polarization

  • All weather

  • DEM

  • Urban density

  • Soil moisture

  • Crop type


SAR Sensors


SIR-C/X-SAR SAR Examples
