-The water mask identifies coastal waters and major inland waterbodies. These areas are assigned a pixel value of 0.

The water mask is stored as an 8-bit unsigned integer GeoTIFF file and is always included in the product package.
+The water mask identifies coastal waters and most inland waterbodies. These areas are assigned a pixel value of 0. All remaining pixels (land, islands, very small inland waterbodies, and landfast Antarctic ice) have a value of 1. All areas between 85 and 90 degrees north latitude are assigned a value of 0, and all areas between 85 and 90 degrees south latitude are assigned a value of 1. The water mask is stored as an 8-bit unsigned integer GeoTIFF file and is always included in the product package.
 
-The water mask is generated by ASF using data from OpenStreetMap(https://www.openstreetmap.org/about) and/or ESA WorldCover(https://esa-worldcover.org/en/about/about) depending on location. Areas within Canada, Alaska, and Russia are primarily covered by ESA WorldCover data, while the rest of the world is covered by OpenStreetMaps data.

Refer to our InSAR Water Masking Tutorial for more information: https://arcg.is/19aKHj
 
 Note that applying the mask after phase unwrapping does not prevent unwrapping errors caused by the inclusion of water pixels as valid data during the phase unwrapping process. When submitting InSAR jobs for processing, there is an option to "Apply Water Mask". Selecting this option uses the water mask to adjust the validity mask used for phase unwrapping. This prevents phase unwrapping from occurring over large expanses of water, which can lead to unexpected deformation signals or phase jumps in the unwrapped outputs. This mask {{ "was" if water_mask_applied else "was not" }} applied during phase unwrapping. Refer to the Unwrapped Interferogram description above (item 2) for more information.
