Jaye, Manager GIS and RS, Forestry Development Authority (FDA) Slide 2 Project Background Previous work by Metria/GeoVille 2011 in a study funded within the joint ESA/WB eoWorld initiative Mapping of forest areas in NW Liberia Detailed forest mapping for 2010, 2007, 2002 Change detection Slide 3 Conclusions from the EOWorld mapping 2011 Products are suitable for local level planning and regional statistics Benchmark for forest monitoring Large areas with low impact from forestry activities ~10 % available by current infrastructure Most forest cover changes in agricultural forest close to settlements Technical specifications Minimum mapping unit of 0.5 ha Spatial resolution of 10 m (5 m) Most recent RapidEye imagery & Landsat 8 used (2012-2014) Object- and pixel based classification Post classification editing by manual interpretation Liberia Land Cover 2014-15 (Legend) Forest >80% Forest 30-80% Forest 2500 inhabitants) Rural (< 2500 inhabitants) provided ancillary data by LISGIS Surface Water Bodies Grassland (Savannah) & Shrubs Bare soil Ecosystem complex (rocks & sand) Slope classes ; 30 %; (separate layer) Elevation (separate layer) Road and railway network (separate layer) Primary road (paved) Secondary road (unpaved) Tracks (backroads) Railways Slide 8 Satellite Data Search and Preparation (Feb May 2014) Landsat data (Feb April 2014) Purchase of RapidEye coverage (May 2014) Funded by European Space Agency Single User Licence End User FDA Workshop in Monrovia April 2014 Anchor the proposed land cover and forest mapping approach and class definitions Collect information for the inception report and technical specifications for the maps and the GIS-tools Training for field validation Inception Report and Technical Specifications (May 2014, Final Aug 2014) Mapping of Test Area - 10% of the area (Oct Dec 2014) Field Survey performed by FDA staff (Nov 20 Dec 3, 2014) Project Milestones RapidEye coverage (85% of Liberia) Slide 9 Project Milestones (contd) Validation Report (March 2015) New cloud-free Landsat 8 data (Dec 29, 2014 Jan 7, 2015) Contract Extension (May 2015) Full area mapping (Apr Sep 2015) Delivery of mapping products (Oct 2015) Digital and hardcopy Remaining work Internal validation results (Dec 2015) Training material and programme (Dec 2015) Training workshop (January 2016) Final Report (February 2016) Independent validation Landsat 8 coverage Slide 10 Outcomes of the project for Liberia Up to date high resolution forest and land cover information Knowledge about forest resources and agricultural land A platform for natural resource monitoring A baseline for the REDD process and carbon monitoring Capacity building for forest mapping & monitoring with Earth Observation Slide 11 Detailed Land Cover Map 2015 compared to 2004 map (from test area) Land cover 2013 (produced by JV Metria/GeoVille) Minimum mapping unit: 0.5 ha Land cover 2004 (Bayol) Slide 12 Mapping Results Land Cover and Forest Mapping - 2015 The classification was done by combining the 5 m resolution of RapidEye (2012-2013) and the spectral information from Landsat 8 (2014 -2015) Landsat-8 mosaicRapidEye coverage (B/W Slide 13 Mapping Results Land Cover and Forest Mapping - 2015 With roads and railroads Slide 14 Some examples Slide 15 Land cover class Hectares% of mapped area Forest >80% 4 389 27045.5% Forest 30 - 80 % 2 186 49522.6% Forest
