660 Dots Per Inch Mapping
We have been supplied with new 660 DPI mapping and the results are simply stunning. Colours are much more faithful to the paper map originals, lettering and contour lines are smoother and clearer. These HD maps are beautiful.
Compare for yourself
Inside the Map Manager, first of all press the ‘Map Sync’ button to update your available maps. Then locate the ‘Anquet Demo Maps’ group and click on the arrow to the left to expand the group of maps. From here you can download the following maps to compare HD and normal mapping: ‘OS 1:25,000′, ‘OS 1:25,000 HD’, ‘OS 1:50,000′ and ‘OS 1:50,000 HD’.
If you have Outdoor Map Navigator Pro installed, you can bring the maps up in Split Screen and view them side by side.
The move to 660 DPI
Anquet Maps have been licensing Ordnance Survey mapping for over ten years. When we started out, the size of the datasets were just huge even for PC’s of the day. Now it’s possible to keep all of this data on a smartphone!
When the Ordnance Survey launched their digital mapping, they specified it for computers of the time, and so all data was supplied at 254 DPI (Dots Per Inch.)
With ever increasing speed and storage capabilities of computers, it was time for the Ordnance Survey to update the quality.
Most modern printers can now also far exceed the original 254 DPI standard data, and therefore 660 DPI data will produce much clearer map prints.
Dots Per Inch (DPI)
HD resolution mapping is 660 DPI, so one square inch of mapping has 660*660 pixels.
Standard resolution Ordnance Survey mapping is 254 DPI, so one square inch of mapping has 254 *254 pixels.
Doing some simple maths: (660*660)/ (254*254) = 6.75 more definition.
Although the source data is sizeable, using our own compression techniques which are well suited to mapping, the growth in file size is very reasonable for the improvement in quality. For instance complete Great Britain OS 1:50,000 HD data is 4GB, compared to 2.7GB for the standard data.
Upgrade to High Definition Maps
When you download a map from Anquet Cloud, you are downloading the exact data from the time that you purchased the map. So if you purchased a Landranger map in say October 2010, whenever you download that map, you would be getting our June 2010 mapping data as that was the newest available map data when the map was purchased.
We only have the new HD mapping that matches to our most recent June 2012 release.
I have bought Landranger maps on or after 1 June 2012
Please contact our sales desk on 01202 286 080, and they can upgrade you to HD for the price difference between the standard and HD product.
Worked Example: Great Britain North 50k bought 1 June 2012 upgrade cost: HD price – Standard price = £87.36 – £72.80 = £14.56 My Landranger maps were bought before 1 June 2012
Please contact our sales desk on 01202 286 080, who can upgrade your maps to 2012 for half the cost of the standard mapping as per our normal terms, and then if you wish to move to HD, the price difference between the standard and HD product would also be charged.
Worked Example: Great Britain North 50k bought 1 June 2010 upgrade cost: Cost to Upgrade to 2012 data = £72.80/2 = £36.40 Move to HD = £87.36 – £72.80 = £14.56 Total cost = £36.40+14.56 = £50.96
