Title

DC2 MHWS 1890s

Abstract

High Water Mark of Ordinary Spring Tide. Digitised from the OS 2nd Edition. Scale 6 inch map (1:10,560) county series. Epoch 1890 to 1959. The 'soft' or erodible shoreline has been mapped, not the whole coastline. For more information see www.dynamiccoast.com. Updated as part of the second phase of Dynamic Coast research (2021).

Lineage

This data was developed as part of the National Coastal Change Assessment (see www.dynamiccoast.com) The high water mark for the soft (erodible) coast was extracted from the OS Six-Inch County Series Second Edition sheets. For the OS Six-Inch Inch County Series Second Edition, the ‘High Water Mark of Ordinary Spring Tides’ (HWMOST) was mapped, and in the ‘OS 1970’s data the Mean High Water Springs (MHWS) was mapped (note this is just a difference of terminology, the definitions are the same). Once the positional accuracy of the mpas were checked and updated against aerial photography, the high water mark was extracted using a combination of manually and automated extraction. The manual extraction required the use graphics tablet which allows the high water mark to be traced using a stylus (within the NCCA the Wacom Cinitq 24HD graphics tablet was used). The autmoted extraction used the ArcScan toolbar with ArcMap. The digitised high water mark was and linked across sheet boundaries, and then assigned the appropriate metadata e.g. survey dates, sheet number, and length (in metres) etc. OS Six-Inch County Series Second Edition Out of copyright with tiles provided by The National Library of Scotland OS 1970’s data was available under the PSGA and this derived data is considered open
