Description: The streams were generated using standard techniques for stream delineation such as the TOPAZ technique. This technique compares the elevation of each pixel to its surrounding eight points. These comparisons will allow the identification of the direction to which the water will flow. It is from the central pixel to the surrounding pixel that has the lowest elevation of the surrounding eight pixels. The process is repeated until the streams are delineated across the entire image. This process was applied on a 10m resolution DEM.

It is from the central pixel to the surrounding pixel that has the lowest elevation of the surrounding eight pixels. The process is repeated until the streams are delineated across the entire image. This process was applied on a 30m resolution DEM.
Description: These are the backscatter difference images for ascending mode. The radar visibility mask for ascending acquisition have been applied. The areas 200 m away from roads are masked.
Name: Ascending Standard Deviation Classified Images
Display Field:
Type: Group Layer
Geometry Type: null
Description: This is the image showing 0 and 1 values. For each ascending backscatter difference image, 1 indicates the areas where difference is higher than 1 standard deviation whereas 0 indicates the areas with difference less than one standard deviation.
Description: These are the backscatter difference images for descending mode. The radar visibility mask for descending acquisition have been applied. The areas 200 m away from roads are masked.
Name: Descending Standard Deviation Classified Images
Display Field:
Type: Group Layer
Geometry Type: null
Description: This is the image showing 0 and 1 values. For each descending backscatter difference image, 1 indicates the areas with difference higher than 1 standard deviation whereas 0 indicates the areas with difference less than 1 standard deviation.
