[Qgis-user] New user puzzled by GRASS Directory structure

[Wayne]

I’m new to QGIS and the GRASS plug-in directory instructions.  Here is my situation.  I have forestry clients that are mostly in one county in the state.  However I some times have a client in a different county.  I have to create vector layers that are unique for each client.  I get all my resource layers from the State either via WMS or downloading specific vector and raster layers and these would be used for each client work.  Many of their layers are for the entire State not for just a part of the State (county).  

What would be the best way to set up the Location and Mapsets for this?  

Also, I see you need to define the Location bounds and you can use an existing layer to set the extent.   If I have a mix of layers I will get from the State—some the entire State and some a section.  Which layer is it better to choose for the Location bounds?  

I have used ArcView in the past so this GRASS Database system sure is confusing.   Thanks for any help.  Wayne
