Dataset details: Madagascar 100m Population
______________________________________________

DATASET: Version 2.0 estimates for numbers of people per pixel ('ppp') and people per hectare ('pph'), for 2010, 2015 and 2020, with national totals adjusted to match UN population division estimates (http://esa.un.org/wpp/), and remaining unadjusted. Note, an additional dataset is included for the census year, on which 2010, 2015 and 2020 estimates are based.
REGION: Africa
SPATIAL RESOLUTION: 0.000833333 decimal degrees (approx 100m at the equator)
PROJECTION: Geographic WGS84 for 'people per pixel' (ppp) datasets; local projection applied for 'people per hectare' (pph) datasets
UNITS: Estimated persons per grid square 
MAPPING APPROACH: Dasymetric modeling approach incorporating a Random Forest estimation technique (model version 2c), as described in:  Stevens, F. R. et al. (2015). Disaggregating Census Data for Population Mapping Using Random Forests with Remotely-Sensed and Ancillary Data. PLOS ONE, 10(2), e0107042. doi:10.1371/journal.pone.0107046. Note, different RF models were combined to produce the final Madagascar output: a nation-wide model and specific models for some cities. City-specific models for Antananarivo and Toasmina are described in separated metadata files. Output maps were mosaicked to obtain one consistent nation-wide map.
