nacispreloader 0.2.4
Preloader of nacis natural earth shapefiles
License: MIT

# README #

This package is a preloader for nacis (North American Cartographic Information
Society) shapefiles.  It is intended to supplement python applications making
use of cartopy shapefiles (which are downloaded from nacis servers). By using
this preloader, the nacis download can be replaced with loading shapefiles from
s3 instead (where available).

Currently includes:
* 10m roads
* 10m, 50m, 110m countries
* 10m, 50m, 110m states_provinces
* 10m, 50m, 110m coastline 
* 10m, 50m, 110m rivers_lake_centerlines 

see http://www.naturalearthdata.com/downloads/ for more information about available shapefiles (those not provided by this preloader).
see also https://gist.github.com/DanielJWood/b71237cc200831acf8e637c05ce2c375#file-natural_earth_s3_links-md for alternate download location for the source shapefile zips.


### How to i use it? ###

from nacis.preloader import Preloader
preloader = Preloader('yours3bucket','yours3prefix')

# preload roads, countries, coastlines:
preloader.preload('roads','cultural','10m')
preloader.preload('countries','cultural','10m')
preloader.preload('coastline','physical','10m')

# make a chart:
import matplotlib.pyplot as plt
import cartopy
import cartopy.crs as ccrs

fig = plt.figure(figsize=(7,7))
ax = plt.axes(projection=ccrs.PlateCarree())
ax.coastlines(resolution='10m', color = 'black', linewidth=1.0)
cartopy.feature.NaturalEarthFeature('cultural','countries','10m')
cartopy.feature.NaturalEarthFeature('cultural','roads','10m')
ax.set_extent([-180,180,-90,90])
plt.savefig('out.png')
plt.close()
