Action: When run, this administrative.makefile download administrative L0 (countries), L1 (subunits), and cities (places) GIS sources, process them (unzip, crop, filter), to output an elegant composite stack of your target L1 district upon L0 backgrounds, as topojson and WP styled SVG files.
Output:
Direct command:
make -f administrative.makefile ITEM=India WEST=67.0 NORTH=37.5 EAST=99.0 SOUTH=05.0 SELECTOR_L1="admin IN ('INDIA')"Parameters:
SELECTOR_L1=… (SQL selector, default value "admin IN ('France')") selects and keeps L1 administrative areas respecting SQL query.SELECTOR_PLACES=… (SQL selector, default value ADM0NAME = '$(ITEM)' AND POP_MAX > '$(POP_MIN)') selects and keeps places administrative areas respecting SQL query.SELECTOR_POP_MIN=… (integer > 0, default value 200000) selects and keeps places (towns and cities) with populations above (>) value. Easier than SELECTOR_PLACES=.QUANTIZATION=… (default 1e4, from 1e3 to 1e6) : maximum number of differentiable points along either dimensionDerivated from ogr2ogr and topojson.js.
[1]: If not there, the download task will automatically download the NaturalEarth countries, subunits, and places archive files totaling about 30MB. This may take from few minutes.
