About the Maps
Our maps are raster maps (made up of pixels/dots, like a digital photo). Although all
the maps make fine wall coverings, particularly the Free Decorative Maps, the relief and land cover maps
are mainly intended as backgrounds for your geographic projects.
If you are not a GIS person, don’t be put off by the word “georeferenced”. You can open
and work on any map on this site using any picture software. If you save a georeferenced map using
non-GIS software, you only risk losing the embedded geodata, which is no problem if you don't need it.
All our georeferenced maps are supplied in Geographic projection (a.k.a. Latitude-Longitude,
Plate Carree, Equirectangular projections). We can supply re-projected and/or resized versions of any of
these maps as part of our
custom map service.
We also offer Miller-projection versions of our georeferenced world maps for customers
who need a ready-made sensibly-projected world map to start painting on.
The non-georeferenced Orthgraphic maps come with sufficient latitude-longitude data to
assist GIS folk to georeference them.
All the maps are supplied with normal colour saturation, brightness, and contrast levels.
To increase the prominence of any data you want to superimpose , simply "fade" any map by adjusting these
values with your software.
Note about rivers: natural physical features such as major lakes and river valleys appear
on both the relief and land cover maps. Major rivers are also discernable on the land cover maps, but rivers
(the water surfaces) are not marked on the relief maps.
Free maps: we recommend you save the free maps directly to your computer, rather than by saving
an image opened in your browser. This will ensure maintenance of image quality, and any embedded geodata.
