ctryShpLyrName2Num

layerName

<p>Get the integer number of the layer. Is the last character in the name 
    and is a digit. E.g. for the 3rd layer in Kenya shapefile polygon 
    named "KEN_adm3" the layer number is <code>3</code>. The lowest layer number
    is <code>0</code></p>

Extracts raster and zonal statistics
from satellite nightlight rasters downloaded from the United States
National Oceanic and Atmospheric Administration (<http://www.noaa.gov>)
free data repositories. Both the DMSP-OLS annual and SNPP-VIIRS monthly
nightlight raster data are supported. Satellite nightlight raster tiles are
downloaded and cropped to the country boundaries using shapefiles from the GADM
database of Global Administrative Areas (<http://gadm.org>). Zonal statistics
are then calculated at the lowest administrative boundary for the selected
country and cached locally for future retrieval. Finally, a simple data
explorer/browser is included that allows one to visualize the cached data e.g.
graphing, mapping and clustering regional data.
