National Ecosystem and Ecosystem Services Map – Land Promoting Good Water Quality

Category: Environment
Views: 109
Openness rating:

This dataset contains a raster file showing the contribution of land to the maintenance of high water quality, though natural filtration of sediment.

This dataset is part of a dataset series that establishes an ecosystem service maps (national scale) for a set of services prioritised through stakeholder consultation and any intermediate layers created by Environment Systems Ltd in the cause of the project. The individual dataset resources in the datasets series are to be considered in conjunction with the project report: https://www.npws.ie/research-projects/ecosystems-services-mapping-and-assessment

The project provides a National Ecosystem and Ecosystem Services (ES) map for a suite of prioritised services to assist implementation of MAES (Mapping and Assessment of Ecosystems and their services) in Ireland.

This involves stakeholder consultation for identification of services to be mapped, the development of a list of indicators and proxies for mapping, as well as an assessment of limitations to ES mapping on differing scales (Local, Catchment, Region, National, EU) based on data availability. Reporting on data gaps forms part of the project outputs.

The project relied on the usage of pre-existing data, which was also utilised to create intermediate data layers to aid in ES mapping. For a full list of the data used throughout the project workings, please refer to the project report.

Provenance information 50m raster grid file used in the Mapping and Assessment of Ecosystems Service Project. Created by Environment Systems Ltd. (ESL). The dataset was derived through additive analysis of relevant spatial data including; 1. Habitat type (Habitat Asset Register, refer to resource 1), 2. NextMap 5m DTM, 3. Teagasc Soil, 4. Teagasc Subsoil, 5. Groundwater Recharge, 6. Groundwater Aquifers 7. Conservation Designations These datasets were scored to represent the contribution of the individual classes to filtration of sediment out of the water. For the full processing methodology, including a comprehensive list of the input datasets, associated scores, full processing methodology, including any modification of the input data refer to the project Final Report (resource 23). The final raster dataset has been created at a cell size of 50m. All processing steps were carried out at a cell size of 50m. Metadata for all input datasets is included with the datasets in question. Filename / Map package / PNG: 3010_MAES15-ESmap_WaterQuality.tif / 3010_MAES15-ESmap_WaterQuality.mpk / 3010_MAES15-ESmap_WaterQuality.png For the full processing methodology, including any modification of the input data, refer to the project Final Report (see Resource 23). Project processing was carried out in EPSG29902. Final outputs were converted to EPSG2157, using the transformation provided by proj4 (https://trac.osgeo.org/proj/wiki/FAQ), which is used by most GIS software for coordinate system manipulation. The source Coordinate Reference System is Irish Transverse Mercator (ITM). The transformation used is equivalent in accuracy to the one held by NPWS. This dataset has been created using various processing and GIS software including; ArcMap 10.1, FME, and QGIS.
