Imperviousness High Resolution Layer Data Series
The European Environment Agency, as lead authority under the Copernicus Land Monitoring Service, co-ordinate the development of Pan European datasets. One of the products produced by the EEA under this programme are the “High Resolution Datasets” which are a data series covering numerous different thematic land uses / land covers. Comparable data is produced across Europe using earth observation methods developed in partnership with private industry. The Environmental Protection Agency, as members of the European network EIONET, provides data quality assessments and disseminates the data for Ireland.
The High Resolution Imperviousness is a data series of products that capture the percentage and change of soil sealing. Built-up areas are characterized by the substitution of the original (semi-) natural land cover or water surface with an artificial and often impervious land cover. These artificial surfaces are usually maintained over long periods of time. A series of high resolution imperviousness datasets (for the reference years 2006, 2009, 2012 and 2015) identifying all artificially sealed areas was produced. This series of imperviousness layers constitutes the main status layers. They are per-pixel estimates of impermeable cover of soil (soil sealing) and are mapped as the degree of imperviousness (0-100%). Imperviousness change layers were also produced as a difference between the reference years (2006-2009, 2009-2012, 2012-2015 and additionally 2006-2012, the later aims to fully match the CORINE Land Cover production cycle) and are presented 1) as degree of imperviousness change (-100% -- +100%), in 20m pixel size, and 2) a classified (categorical) 20m change product.
There are additional 100m pixel resolution products available on the <a href=" https://land.copernicus.eu/pan-european/high-resolution-layers"> Copernicus Land Monitoring Service </a>website, these were excluded from the EPA GeoPortal as the national verification team made and assessment that the 20m provided better information. Technical deails of the imperviousness data series are available <a href=" https://land.copernicus.eu/user-corner/technical-library/hrl-imperviousness-technical-document-prod-2015"> here. </a>

- Statement
-
The series of high resolution imperviousness datasets (for the 2006, 2009, 2012 and 2015 reference years) with all artificially sealed areas was produced using automatic derivation based on calibrated Normalized Difference Vegetation Index (NDVI).
During production of the Imperviousness data series the EEA 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 is given to targeting 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 Imperviousness data for 2015 is that the overall quality, based on look and feel assessment, is good in urban areas but insufficient in the rural areas of Ireland. In rural areas there is significant settlement in villages and via ribbon development along the national road network, this data is not captured well in the imperviousness data. Statistical verification carried out by the national verification team and based on random point sample assessments highlights a significant level of commission and omission errors. The primary issues were experienced when transitioning to the more rural areas of Ireland but there were also issues identified with mineral extractions sites being classified as impervious areas. It was also noted that there were inconsistencies between different regions of Ireland with some regions having better accuracy than others.
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.
