Validation Check S98_Dev7002

Initial values from Excel workbook dated 23 October 2024

DevID: S98_Dev7002 Classification: Critical Error Check Message: S-102 depth values error Check Description: S-102 depth values (excluding noData, defined by bounding rectangle) shall only spatially intersect the following Group 1 features (S-101):

1. Depth Area
2. Dredged area Check Solution: TBD Products: S-102/S-101 Inputs: Dataset vs Dataset

Notes from 25 November 2024 meeting: Consider vector geometries vs. raster geometries Consider explicitly listing features not allowed for intersection Consider adding unsurveyed areas to allowed list Consider making distinct the two cases of partial overlap and total overlap Consider leaving as critical for largest scale ENC but relegating to Warning on smaller scale ENCs.

The word “bounding rectangle” is not defined precisely enough. Does it mean the boundary of each individual pixel/grid cell of the coverage or the boundary of the data area of the coverage?

If it is the data area, then this creates a problem. The bounding rectangle of the data area can also contain NoData pixels/grid cells, which then overlay the corresponding non-permitted Group 1 objects. The only all-encompassing description of the boundary of the pixel/grid cell or the data area is therefore a polygon. The graphic explains this.

• The word “rectangle” should therefore be replaced by “polygon”.
• Furthermore, it should be defined more precisely what “bounding” refers to (pixel/grid cell or data area of the coverage).
