| CityData and CountryData property "Coordinates" gives results in lat-long, but the "Coordinates" property does not have have any built-in projection syntax. GeoGridPosition converts lat-long coordinates into {longitude, latitude} needed for display... |

| The outter List layer of your data was giving FindFit some heartburn. I had to remove that with First. The result of FindFit is replacement rules of the form {R1 -> val1, R2 -> val2, R3 -> val3, ...}. These rules will directly replace the matching... |
