Question

Were is the best way to get MrSID map layers? (it doesn't matter if there are free or not)

What about cadastral survey map base layers?

THANKSSSSS!!!!!!!!!!

Answer 1

MrSID -- Multi-resolution Seamless Image Database layers are developed by a number of vendors.  If you want them, you can either purchase them from the vendor or you can borrow the dataset from someone who has already purchased the data.

Cadastral (property tax) map base layers is ambiguous.  Are you talking about the parcel information?  Or are you talking about the raw street information.  If you want the parcel information, you need to contact the local governmental authority, they are the owners of record.
