There are a couple of websites, where you can create a map of the countries you visited, e.g. http://www.amcharts.com/visited_countries. I think, this would be a cool thing to add to my travel blog. However, all pages I could find, use a Mercator projection for the map, which I don't particularly like. I was wondering, if anyone knows of a way to create these kind of maps for different map projections (like Hobo-Dyer or Gall-Peters).
Basemap offers a wide range of projections, (see here), and you can then plot your places that you have been to onto the map. This can then be saved in a variety of formats for posting on your blog or you can use something like plot.ly to produce them online. A good example in an iPython notebook, (but using the global temperatures), is here with nice explanations of how it was done.
An example of the code needed to make a projection, (with a single point):
from mpl_toolkits.basemap import Basemap import numpy as np import matplotlib.pyplot as plt width = 28000000; lon_0 = -105; lat_0 = 40 # Change the origin lat/long here m = Basemap(width=width,height=width,projection='aeqd', # Change projection here lat_0=lat_0,lon_0=lon_0) # fill background. m.drawmapboundary(fill_color='aqua') # draw coasts and fill continents. m.drawcoastlines(linewidth=0.5) m.fillcontinents(color='coral',lake_color='aqua') # 20 degree graticule. m.drawparallels(np.arange(-80,81,20)) m.drawmeridians(np.arange(-180,180,20)) # draw a black dot at the center. xpt, ypt = m(lon_0, lat_0) m.plot([xpt],[ypt],'ko') # draw the title. plt.title('Azimuthal Equidistant Projection') plt.show()
The results: Once you have the basic process set up you can change the projection or the projection center in seconds.
