[Qgis-user] File-based Mastermap

[Andreas Neumann]

 Perhaps you could also look into SpatiaLite.

 It comes without the limitations of Shapefiles (column names, file 
 sizes) and is fast and a database without installation (file based).

 Also you need to copy only one file instead of multiple ones.

 SpatiaLite is not yet supported by FME (will be supported from FME 2013 
 on I heard) - but you can use ogr2ogr for file translations.

 I believe the new DB-Manager Plugin from the last Google Summer of Code 
 can also assist in converting data from Postgis to SpatiaLite, but I am 
 not 100% sure.
