Base and background layers

What is it: 

The base and background layers give the data on MS Maps NMPi a locational context. Terrestrial and marine data sources are available:

There are six terrestrial layers:

  1. Positron - Tiles by CARTO
  2. Open Street Map
  3. Ordnance Survey GB Premium Stack to MM Topo
  4. Ordnance Survey GB Premium Raster Stack to MM Topo
  5. Ordnance Survey GB Premium Stack to MM Topo (Grey)
  6. Ordnance Survey GB Premium Raster Stack to MM Topo (Grey)

There are two marine data feeds, in the 'Aerial photography, hydrographic charts, and bathymetry (background layers)' layer group:

  1. Bathymetry (OceanWise Marine Themes DEM)
  2. Raster Charts XL (OceanWise) (Not visible at all scales) (geographical coverage variable)

These maps are supplied by a Web Service and are maintained by the separate data originators

Data originators: 
OceanWise
OpenStreetMap (OSM)
Ordnance Survey (OS)

More Information: 

Charts, by their nature for safety of navigation, do not need coverage at all scales for all geographical areas. When populating a portal, such as NMPi, with a web feed this means that if users pan around the screen at a single scale the resolution of the visible charts may change (particularly at chart edges). To ensure that the maximum detail charts (mainly inshore and some offshore areas) are available at zoomed in levels results in areas that have lesser detail chart coverage experiencing some loss of resolution and possibly some electronic artefacts from others scales appearing along the coastline. Users are recommended to switch zoom levels to ensure best view. Due to the resolution of the bathymetry data feed, the Marine Themes data layer is not available at all zoom levels
