So I've started working for a company where people use background data like rivers, buildings, roads and so on a lot. The data is used all over the country, so I have to download a lot of data for each municipalities in my country.
I want to set up a layer file, so that i.e builing data have the same symbology all over, even though it might be 100 different shapefiles for this data. I want all maps to have the same color code and symbology, even if I update the data twice a year, or the shapefiles are from different areas.
What is a good approach for this problem?
