*Note that this is a work in progress. I am new to ESRI mapping and ArcGIS as well. Data available for each country is variable and takes time to verify. I present what I find but available data is not consistent from nation to nation. If you'd like to help add in more information for your region please shoot me and email at salmonfolkfilms *at gmail.
