ESA - CCI LAND COVER S2 PROTOTYPE LC MAP AT 10M OF MESOAMERICA


INFO

The CCI Land Cover (LC) team is proud to announce the successful development of
a prototype high resolution LC map at 10m over Mexico and Central America based
on more than 2 years of Sentinel-2A and 2B observations from January 2016 to
March 2018. The main objective of the 'S2 prototype LC map at 10m of
Mesoamerica' release is to collect users feedback in order to improve the next
generation of HR Land Cover products and drive the R&D activities to achieve
that objective.

The Coordinate Reference System used for this dataset is a geographic coordinate
system (GCS) based on the World Geodetic System 84 (WGS84) reference ellipsoid
and using a Plate Carrée projection.

The typology of the 'S2 prototype LC map at 10m of Mesoamerica' was defined
using the Land Cover Classification System (LCCS) (FAO) which defines LC classes
using a set of classifiers. The system was designed as a hierarchical
classification, which allows adjusting the thematic detail of the legend to the
amount of information available to describe each LC class, whilst following a
standardised classification approach.

In this LC mapping exercise, the regional landscape of Mexico and Central
America is described in 10 generic LC classes: "trees cover areas", "shrubs
cover areas", "grassland", "cropland", "vegetation aquatic or regularly
flooded", "sparse vegetation", "bare areas", "built up areas", "snow and/or ice"
and "open water".

The classification chain is organized into 3 main steps: (i) the preparation of
the training dataset and generation of a stratification layer using auxiliary
datasets, (ii) the generation of a LC map using a random forest classifier on
the Sentinel-2A and 2B Level 2 TOC time series and (iii) the application of
post-edition rules to reformat the generated LC map into the standards of the
ESA CCI-LC S2 prototype LC map of Mesoamerica at 10m. Further information can be
found in the ESA CCI-LC Algorithm Theoretical Basis Document 2018.

The qualitative assessment is done through comparisons between the 'S2 prototype
LC map at 10m of Mesoamerica', the North American Land Change Monitoring System
for Mexico (MEX-NALCMS) (Latifovic et al., 2012), Globeland30 (Chen et al.,
2014) at 30m spatial resolution and very high resolution imagery.

The 'S2 prototype LC map at 10m of Mesoamerica' accuracy was estimated over a
significant set of locations in Mexico by comparison with reference data
collected for the year 2018. The validation process independence is ensured by
using a validation dataset not used during the generation of the product.
Further information can be found in the ESA CCI-LC Product Validation and
Intercomparison Report and in the Memoria de actividades en la validación del
mapa de México y Centroamérica.
