RSPO Southeast Asia Landcover 2010

Collection of Land Cover products for Canada as produced by Natural Resources Canada using Landsat satellite imagery. This collection of cartographic products offers classified Land Cover of Canada at a 30 metre scale, updated on a 5 year basis.

Land cover polygons over Indonesia, classified from Landsat-5 imagery acquired on 7 August 2005. Each feature records the land cover class, sensor, date, area in square metres and hectares, and a confidence rating. Published by Orion Terrametrics.

Land cover polygons over Indonesia, classified from Landsat-7 imagery acquired on 26 May 2002. Each feature records the land cover class, sensor, date, area in square metres and hectares, and a confidence rating. Published by Orion Terrametrics.

The NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Global Food Security-support Analysis Data (GFSAD) data product provides cropland extent data over Southeast and Northeast Asia for nominal year 2015 at 30 meter resolution (GFSAD30SEACE). The monitoring of global cropland extent is critical for policymaking and provides important baseline data that are used in many agricultural cropland studies pertaining to water sustainability and food security. The GFSAD30SEACE data product uses the pixel-based supervised classifiers, Random Forest (RF), to retrieve cropland extent from a combination of Landsat 8 Operational Land Imager (OLI), Landsat 7 Enhanced Thematic Mapper Plus (ETM+), and elevation derived from the Shuttle Radar Topography Mission (SRTM) Version 3 data products. Each GFSAD30SEACE GeoTIFF file contains a cropland extent layer that defines areas of cropland, non-cropland, and water bodies over a 10° by 10° area. Known Issues * Certain small islands in the Pacific are not classified and therefore data for these areas are not provided. * Additional known issues, including constraints and limitations, are provided on page 19 of the ATBD.

Distribution of peatland that covers the tropics and sub tropics, excluding small islands. It was mapped in 231 meters spatial resolution. Peat is here defined as any soil having at least 30cm of decomposed or semi-decomposed organic material with at least 50% of organic matter. This corresponds to 29% of carbon content using 1.72 as the transformation factor. The peatland map is produced by adding the peat forming wetlands: mangrove (20), swamp/bog (30), Fen (40), riverine (50), and floodswamps (60) (note: the number in parentheses refer to pixel code of each class in Wetlands dataset). Our map of peatlands was contrasted against n=275 geo-positioned soil profiles containing peat, with 65% of agreement. Further fieldwork is however needed to validate our map. Mangroves are here considered to host the thresholds of depth and organic matter content needed for peat definition, although mineral soil may prevail. Mangroves contribute with ca. 180,000 km2 to the 1.7 million km2 of peatlands (11%), which would need further ground validation (i.e. in areas like Indonesian Papua have large extents of mangrove that contribute to peat, which would need ground-truthing to validate if they contain peat as defined here).

Polygon features representing land cover in Indonesia, published by Orion Terrametrics. Each feature records a land class, area, sensor date and sensor, with Landsat-8 imagery from 3 August 2015.
