Metadata: Bait digging areas 2019/2020
Abstract:
The data has been collected under a contract run under the Wales non-licensable activities project. Bait digging and collection of living resources was identified as an activity which is causing damage to the Marine Protection Area (MPA) network in Wales. The data obtained from this contract provides NRW with evidence which will help inform discussions around future management of this activity. A GIS layer was created through interpretation of the visible evidence of bait digging from the aerial images (NRW_DS124825 Bait digging areas aerial imagery 2019/2020). The GIS layer was created by digitising around areas identified as impacted by bait digging. In addition the layer displays site name, confidence in interpretation, the age of the evidence (old/new) and digging intensity (low, medium and high) along with who captured the data, the date and image date.

| Internal code | Internally assigned metadata identifier | 8860 |
| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | Bait digging areas 2019/2020 |
| Alternative title | The purpose of alternative title is to record any additional names by which the dataset may be known. | Intertidal Drone Photos 2019-2020.lyr, Bait digging areas (2019-2020).lyr |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | NRW_DS124806 |
| Resource Identifier | This is the code assigned by the data owner. | 4f4c4942-4343-5764-6473-313234383036 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | dataset |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2019-09-30 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2020-03-13 |

| Abstract | The abstract provides a clear and brief statement of the content of the resource. | The data has been collected under a contract run under the Wales non-licensable activities project. Bait digging and collection of living resources was identified as an activity which is causing damage to the Marine Protection Area (MPA) network in Wales. The data obtained from this contract provides NRW with evidence which will help inform discussions around future management of this activity.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | To produce the GIS layer (BaitDiggingAreas20192020), a virtual raster was created for each site using the aerial imagery as tiles. A 100m grid was applied over each site to ensure all areas of the site were examined. Aerial imagery was inspected at 1:250 scale. A scale of 1:500 was used to review areas where evidence of bait digging was not expected, and squares checked off when reviewed. The site surveyor and the digitiser discussed mapping of polygons in the areas visited by foot. The digitiser established what could be identified. It should be acknowledged that this layer has been created using the contractor’s interpretation of imagery (along with some ground truthing) and is not likely to represent a complete picture of damage at these sites. It also represents a snapshot in time. |
