Method Detail

load

public org.openstreetmap.atlas.geography.atlas.Atlas load(java.lang.String input,
                                                          java.lang.String country)

Loads an Atlas from the input location

Parameters:

input - location of the Atlas source

country - country of the Atlas

Returns:

Atlas representation of the data source

load

public org.openstreetmap.atlas.geography.atlas.Atlas load(java.lang.String input,
                                                          java.lang.String country,
