Ordnance Survey 1:25,000 scale Explorer Mapping of Complete Great Britain.
OMN Pro Software
All of these products contain our OMN Pro software.
We have four different configurations:
- Standard Definition (SD)
The original specification of digital maps that the Ordnance Survey launched which are drawn at 254 dots per inch.
- High Definition (HD)
The Ordnance Survey more recently released their High Definition data, from which they print their actual paper map series. These are 660 dots per inch, and therefore offer up over six times the resolution of Standard Definition maps.
- Standard & High Definition
We find many users have a requirement for both High and Standard Definition maps such as using High Definition at home for perfect printing, and Standard Definition on say a smartphone to save on storage requirements.
- Ultimate SD & HD
Take the High Definition OS 1:25,000 scale Explorer maps in both SD and HD formats, and then also add four more maps from Ordnance Survey that cover the same area: OS 1:50,000 Landranger SD, 1:50,000 Landranger HD, 1:50,000 scale GroundRanger and 1:10,000 scale OS Open Map Local.
USB or USB/Download?
Download is simply cheaper, so if you have a good broadband connection download is probably the way to go. If you aren't sure, give the download a try, and if you change your mind, we can send out a USB memory key for the difference in price.
