Purpose

The aim of the Grassland data layer is to identify grassland and non-grassland areas for the reference year 2015. The expectation is that this data is a comparable product across Europe.

Statement

The Grassland high resolution dataset uses 2015 as a new baseline reference year for the product. It fully replaces all previous 2012 reference year products. As a reaction to the lessons learned from the 2012 production, the approach was drastically changed, and the 2015 product is based on a longer time series of imagery from a few different sensors. In addition, the EEA combined radar (SAR) data and optical data for the first time to improve the classification accuracy.

The aim by the EEA is for the thematic accuracy is for 85% to be achieved within each biogeographic region, this assessment will be made on the primary layer, the grassland mask. A quantitative approach will be used based on a set of stratified random point samples compared to external datasets (e.g. GoogleEarth, national orthophotos or national grassland datasets). Assessments by the EEA shows an overall accuracy of 96.66% and a geometric accuracy of less than half a pixel, this is according to the ortho-rectified satellite image base delivered by ESA.

However, the EPA quality assessment of the Grassland HRL data for 2015 for Ireland is that the overall quality is of insufficient quality with significant miss classification from both a commission and omission perspective. A lot of improvements are required to resolve many of the issues identified around the miss capture of grassland areas in urban centres and sports facilities. The verification work also highlighted intermittent capture of grassland throughout the country and the poor delineation of grassland boundaries. Currently data in Ireland will always be a better data source meaning the current usage of this data in Ireland is likely to be limited.

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.
