January 2022 product notes
The following page outlines observations made from product testing and observations which are of note to users of the product. Ordnance Survey is working towards fixing these errors for the next release.
Language qualifiers
The xml:lang attributes are not populated in the product. They are planned for population in a future product release where a feature has more than one name.
Name continuity
The names of watercourses in the product are not all continuous throughout their extent.
HydroNode categories
There are a number of errors with HydroNode features with the hydroNodeCategory value 'Source' and 'Outlet', where the flowDirection of the connected WatercourseLink is in the wrong direction or is unknown.
Geometry issues
There are a number of WatercourseLink features which self-intersect. The vast majority are at the mm level and were created by rounding processes. These will be fixed in a future release.
There are a small number of WatercourseLink features which are shorter in length than 1m. There are a small number of WatercourseLink features which form a closed loop.
There are a number of double digitised WatercourseLink features across the product.
