2014 Ortho OSNI — OpenDataNI

The primary objective from this project was to acquire historical shoreline information for all of the Northern Ireland coastline. Having this detailed understanding of the coast’s shoreline position and geometry over annual to decadal time periods is essential in any management of the coast. The historical shoreline analysis was based on all available Ordnance Survey maps and aerial imagery information. Analysis looked at position and geometry over annual to decadal time periods, providing a dynamic picture of how the coastline has changed since the start of the early 1800s. Once all datasets were collated, data was interrogated using the ArcGIS package – Digital Shoreline Analysis System (DSAS). DSAS is a software package which enables a user to calculate rate-of -change s tatistics from multiple historical shoreline positions. Rate-of-change was collected at 25m intervals and displaye Publisher: OpenDataNI (via data.gov.uk). Delivered as a cleaned, analysis-ready CSV table.
