In chrisvwn/Rnightlights: Satellite Nightlight Data Extraction

Description

Given a list of countries, this function will provide alist of VIIRS nightlight tiles that intersect with them. This helps in processing multiple countries by determining which nightlight tiles are required for processing by allowing the download of all required tiles before processing. Note all VIIRS_* nlTypes have the same nlTiles.

Usage

getCtryTileList(ctryCodes, nlType, omitCountries = "none")

Arguments

ctryCodes	character vector of country codes to process
nlType	character string The nlType of interest
omitCountries	countries to exclude from processing. This is helpful when the number of countries to exclude is smaller than the number to process e.g. when one wants to process all countries and exclude countries that take long to process i.e. omitCountries = "long"

Value

TRUE/FALSE

Examples

Rnightlights:::getCtryTileList(ctryCodes=c("BDI", "KEN", "RWA", "TZA", "UGA"),
    nlType="VIIRS.M", omitCountries="none")

#only 1 tile for OLS
Rnightlights:::getCtryTileList(ctryCodes=c("BDI", "KEN", "RWA", "TZA", "UGA"),
    nlType="OLS.Y", omitCountries="none")
    #returns "DUMMY"
