N2 - Determination of the spatial extent of peatlands and monitoring their
status is important for the evaluation of soil carbon stocks and
greenhouse gas fluxes. At European Level there is a need to provide
accurate and updated estimate of the distribution of peatlands.
Comparison of national data with EU wide land cover mapping shows that
there is limited compatibility between the different data sets. In this
study a methodology of standardized mapping and monitoring of peatlands
at regional level (national to supra-national bio-climatic regions), is
presented. This methodology, based on the enhanced integration of
existing thematic maps through GIS analysis in combination with remote
sensing, has been applied to Estonia, as study case. Existing national
maps and field inventory of Estonian peatlands have been used for a GIS
based evaluation of peatlands relevant information contained in Corine
Land Cover. Remote sensing has been employed in 2 ways: a multispectral
approach using Landsat TM and a phenology oriented time series analysis
of SPOT VEGETATION NDVI both implemented for the entire territory of
Estonia. The remote sensing results are evaluated against the existing
high resolution Estonian map of peatlands. In the case study it has been
shown that peatlands are both spectrally and phenologically clearly
distinct from other land cover types and therefore have a good potential
to allow semi-automated mapping over large areas with relatively high
accuracy, which lays the basis for efficient monitoring and mapping of
peatlands change.
