I have been using databases for years and have used QGIS since 1.8 for
general mapping. I know it can use additional data attached to the
geographic data via a union query to display lots of different things. I
have map areas where population density would be nice to display using
different background fill colors bases on that density. I just need a bit
of a boost getting the idea as to how to start and which way to go.
I have been using the program with SpatiaLite database. Do I need to go
tto the PostGis db? Most of my other data is currently in MySQL.
Thanks for amy advice / guidance!!
