Hi I am trying to make a map of Sierra Leone and am running into trouble. I am brand new at this so I will explain what I have done so far. Please don't be impressed by all the fancy code that follows. I have no idea what I am doing. The code was lifted from random places around the web.
SL has 4 provinces: Northern, Southern, Eastern, and Western, which are diced up into 14 districts as shown here:
http://en.wikipedia.org/wiki/Administrative_divisions_of_Sierra_Leone
I found I could create Entity's for 13 of the 14 districts via the following:
districts = {"Bo Sierra Leone", "Bombali", "Bonthe District", "Kailahun District",
"Kambia District", "Kenema District", "Koinadugu District", "Kono District",
"Moyamba District", "Port Loko District", "Pujehun District", "Tonkolili District",
"Western Rural District", "Western Urban Sierra Leone"};
slDistricts = SemanticInterpretation /@ districts
GeoListPlot[slDistricts, ImageSize -> Large, GeoLabels -> True]
but it fails to make the district of Bo and instead returns a city. There are apparently two problems. One is that SemanticInterpretation fails to make an Entity for the district of Bo which seems to bode ill for me. The other is that I can't get it to generate maps of the other 3 districts in Southern either. Is there some way to "teach" SemanticInterpretation that there exists a an AdministrativeDivision in Sierra Leone named Bo and also to somehow update the information that the Geo routines are using so that they'll plot the 4 districts in Southern.
I also tried plotting single districts and it fails for all the ones in Southern. As you can see I could get maps of districts in Northern and Western, but the attempts to map the 4 districts in Southern failed.
