Ordnance Survey 1:25,000 scale Explorer Map:
183 Chelmsford & The Rodings
This map covers the exact same geographical area as the paper equivalent sold by the Ordnance Survey. The map coverage image shows the exact area covered.
The sample mapping image is not geographically from the area that this product covers, but is provided to illustrate the standard of mapping being provided.
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 Defintion at home for perfect printing, and Standard Definition on say a smartphone to save on storage requirements.
- Ultimate SD & HD
Take the Standard and High Definition maps, and then also add four more maps from Ordnance Survey that cover the same area: OS 1:50,000 Landranger SD, OS 1:50,000 Landranger HD, 1:10,000 scale OS Street View and 1:50,000 scale GroundRanger.
