Creating external map - formats and size?
I have the whole of the UK in Ordnance Survey 1:25 as 10km squares in TIFF (not geo tiff) with TAB and TFW files for location data.
I understand i need to change the format with MAPC2MAPC for Locus.
Should i keep the map as 10km tiles (there are 2700 tiles)
merge to one large map (whole of uk, 12GB)
split into a couple of maps (<2GB?)
What is the best format?
I see sqlitedb mentioned a lot but is GEMF more efficient?
I have converted one tile as a test and its size as a TIFF was 400kb + 2kb for TAB. Its size then became 2.7mb as a sqlitedb and 2.2mb as GEMF.
Is this growth normal? The TIFFS are already 12GB total.
