Comments

The RGB ECW mosaic is consistent with the coverage offered by the source 1km tiles. 

Missing Data

Comments

The RGB ECW mosaic provides the same coverage as the source 1km TIFF tiles. All ISC rivers in the CMA are covered to a width of 2-3km across the river. The image space in between the original imagery strips (ie, the un-imaged areas) contain NULL data.
