Purpose

The aim of the Water & Wetness data series is to identify areas that are either permanent water, temporary water, permanent wetness or temporary wetness. The expectation is that this data is a comparable product across Europe.

Statement

The water and wetness layer is based on multi-temporal and multi-seasonal optical high-resolution satellite imagery. In addition to this it is also based on radar information (Sentinel-1 data) with a geometric resolution of 10m on a pan-European basis. A multitude of optical and SAR imagery is used, covering a prolonged time series of 7 years, which aim at capturing the intra-annual dynamics as much as possible within a given area and lead to one image composite per season (each season covered by 3 months) and year during the observation period.

Quality assurance follows the ISO9000 standards for Quality Management and comprises of dedicated procedures of ongoing quality checks (QA breakpoints) during implementation of the production chain, in order to keep persistent control over the various stages of production, assure fitness-for-purpose of the end-products and that all quality requirements are fulfilled. Priority has been given to the target thematic accuracies to be achieved by each product, as well as to the issues of product consistency (spatial, thematic, temporal) and homogeneity.

Quality Assessment: The quality assessment has been performed according to INSPIRE Data Specifications. The data quality elements considered are:

(i) Completeness,

(ii) Logical Consistency,

(iv) Thematic Accuracy,

(v) Temporal quality and

(vi) Usability.

Each of them (excl. the Thematic Accuracy hereafter) forms a section in the QA/QC Procedures.

The EPA quality assessment of the Wetness and Water HRL data for 2015 for Ireland shows that the overall quality of the data is insufficient. The assessment by the national team highlighted that some strata, particularly permanent water, are captured and identified accurately with good spatial accuracy. However, the capture of peatland and temporary wet areas was very poor. Considering the importance of these landcover types within the Irish landscape and their impact on climate change accurate data is essential. Peatland and temporary wet areas cover a large proportion of the national landcover and the poor quality of the HRL data for these strata brings the overall quality of the dataset into question. In Ireland, better quality national data is required to managed and monitoring peatland and temporary wet areas, therefore until there is significant improvements in this data the EPA sees limited use of this data at a national scale.

The reports developed as part of the national assessment and verification process a have been submitted to the EEA with the aim of addressing the primary issues during the production process of future datasets.
