IKONOS Imagery
Metadata:
The CPC Ecuador Spatial Database contains 9 IKONOS scenes for different sections
of our study area. The scenes span the time frame from 10/25/2000 to 02/09/2002.
General metadata is below, containing information relevant to all scenes.
Specific metadata follows, containing the details for each individual scene.
General Metadata:
- Abstract:
-
Each scene contains two images: a multispectral and a panchromatic. The
multispectral image has four spectral bands that correspond to Blue, Green, Red,
and Near Infrared portions of the electromagnetic spectrum. The panchromatic
image is one grayscale image that covers the entire electromagnetic wavelength
range covered by the multispectral image.
- Source:
-
All scenes were acquired from Space Imaging
through the University of New Hampshire's
EOS-WEBSTER program.
- Spatial Resolution:
-
Multispectral - 4 meters
Panchromatic - 1 meter
- Spectral Bandwidth (μm):
-
Band 1: 0.445 - 0.516
Band 2: 0.506 - 0.595
Band 3: 0.632 - 0.698
Band 4: 0.757 - 0.853
Panchromatic: 0.526 - 0.929
- Horizontal Accuracy:
-
The data were all processed at the Standard Master level of precision, resulting
in a horizontal positional accuracy of ± 12.2 meters.
