  • Last Amended: 3 September 2001 From Marine Maps you can create a map from one of six predefined scale bands based on the Charted Raster product. The maps in each scale band can be zoomed in and out to best display the selected area. The map can be viewed on screen or printed at A4 size as a PNG format file. The Marine Lexicon (based on the International Hydrographic Organization's ecPilot demo) allows the user to explore the symbols and abbreviations used on Admiralty Charts that are used within Marine Maps. Marine Lexicon is available to any registered user. The Marine Lexicon (based on the International Hydrographic Organization's ecPilot demo) allows the user to explore the symbols and abbreviations used on Admiralty Charts that are used within Marine Maps.

  • Last Amended: 3 September 2001 Admiralty Charts – come from SeaZone Solutions Ltd, which is part of the UK Hydrographic Office. hydrospatial is 2008 and 2009 has just arrived - not sure when it'll go live yet (3 Sept 2009) charted raster is 2006 The Usage Band's map scales used in Marine Maps are as follows: Ocean - small scale ( 1:3,500,000 to 1:750,000) Sea - small scale (> 1:750,000 to 1:300,000) General - small to mid scale (1:200,000 to 1:100,000) Coastal - mid scale ( 1:100,000 to 1:50,000) Approaches - mid to large scale ( 1:50,000 to 1:15,000) Harbour - large scale ( 1:25,000 to 1:2,500) Why can I see black triangular slivers around some of the Marine Maps? The Marine Maps facility in Marine Digimap uses the Charted Raster product to build up a mosaic of maps for each scale band. These mosaics are made up of many different maps and each one has its own geographical projection. In order to display the mosaics as a continuous map each individual map has to be reprojected so that they are all the same. As most of the maps' projections are very similar they fit well together. However, some have been rotated considerably to fit with the other maps; in these cases it is possible that you will see black triangular slivers between them and the surrounding maps.

    36. 36. Marine Maps • Online map creation, uses scanned Admiralty Chart images (Charted Raster data) • Print/download A4 maps • The maps are grouped into 6 scale bands; ocean, sea, general, coastal, approaches and harbour (roughly equivalent to the usage bands of Admiralty Charts). • Each scale band features a different set of Admiralty Charts, with features most relevant to the scale. The scanned images are used to build up a mosaic of maps for each scale band. • Scales vary from 1:3.5million to 1:2,500. • These make ideal backdrop maps, but must NOT be used for navigation.
    37. 37. Scale/Usage bands • Ocean - small scale ( 1:3,500,000 to 1:750,000) • Sea - small scale (> 1:750,000 to 1:300,000) • General - small to mid scale (1:200,000 to 1:100,000) • Coastal - mid scale ( 1:100,000 to 1:50,000) • Approaches - mid to large scale ( 1:50,000 to 1:15,000) • Harbour - large scale ( 1:25,000 to 1:2,500)
    38. 38. Marine Maps • Source maps may be at different scales. • In Marine Maps, maps of different source scales are viewed at same scale…so you may find some differences in detail in adjacent areas.
    39. 39. Opening screen
    40. 40. Marine Maps home page • Use the drop down menu to view areas covered by different usage bands. • To search, enter details in a search box or click on the map to go to your area of interest.

    49. 49. Onward use of data in ArcGIS Hydrospatial data: • Older versions of ArcGIS not supported. Can’t guarantee data will work in ArcView 3.x • Shape files, no need to convert • All of the files provided with Shape files must be kept in the same folder • To view data as it is seen in Marine Digimap, need to download and install 2 folders with cartographic styles and apply these: – fonts.zip – style.zip • Folders and information on applying styles available in Help > Using data with ArcGIS
    50. 50. Content  What is Marine Digimap?  What can I do with Marine Digimap?  Marine Roam  Marine Maps  Hydrospatial Data Download  Charted Raster Download
    51. 51. Charted Raster Download – 4 step process
