Source (Input) Data:

Imagery:

· Spectral Bands: All four Landsat MSS bands,

· Coverage: Single Landsat WRS Path/Row,

· Projection/Datum: SOM / WGS84,

· Pixel Size: Mixture of 57.0 and 60.0 meters,

· Interpolation Method: Cubic Convolution,

· Orientation: Path oriented,

· Coverage Date: Scene dependent (nominally from 1972 to 1978).

Control:

· Horizontal: Control was passed from the GeoCover orthorectified Landsat TM imagery of same area.

· Vertical: DTM with 3-arc second postings, where available. Where 3-arc second data not available, GTOPO30 (30-arc second ) digital elevation models are used.

Digital Image Processing:

· Automatic Image-to-Image registration:
Performed using Earth Satellite Corporation’s proprietary software, which locates favorable site passes the control (via cross correlation) from the geodetically accurate TM imagery to the input MSS imagery.

· Orthorectification:
Resampled to a UTM/WGS84 projection using nearest neighbor (i.e. no interpolation).

· Image Enhancements:
The data are spatially and spectrally unenhanced.
