Why Usera?
Migrants make up 12% of Spanish population
Five-fold increase since the 1990s
Starting in 2000 large numbers of Bolivians
began immigrating to Spain
Today, 4% of the Bolivian GDP comes from
remittances, most of which come from Spain

My Plan
Initially:
Make data usable for Arc/Geocoding
Geocode using the addresses
BUT:
Yo no habla español
Madrid street layers unavailable
My Plan
Map the data using the latitude/longitude data
Convert the coordinates into Decimal Degrees
X in decimal degrees=degrees + minutes/60
+seconds/60
Latitude (N) Longitude (W)
40° 23.179 3° 42.023
