  \section overviewCoast Overview
  
  Coastlines are stored in SHP files and are stored in <i>share/magics/??m</i> directories.
  The shape files are downloaded from <a href="http://www.naturalearthdata.com/">http://www.naturalearthdata.com/</a>.
  
  \section sourceCode Coding
  
  - Parameters are defined in src/xml/CoastPlotting.xml
  
  - Generated files src/visualisers/BoundariesAttributes.cc src/visualisers/CoastPlottingAttributes.cc src/visualisers/CitiesAttributes.cc
  
  - Code for shape file reading is in src/decoders/ShapeDecoder.cc
  
  - Code for coastline processing src/visualisers/CoastPlotting.cc
  
  \section Boundaries Boundaries

  \section readingOfShape Pre-processing and reading of Shape files

  Only the following extensions are required for shape files: [ dbf, shp, shx, prj ]. Extensions .sbn and sbx are undocumented formats used only by ESRI software.

  To extract subsets of shape files into other shape files use the ogr2ogr command line utility (from gdal) as follows:
 
      ogr2ogr <output_folder> <input_shape_file>.shp -where "<condition>"

  For example, to ignore minor feature data in the 10m shape files we did the following:

      ogr2ogr output_folder 10m_lakes.shp -where "ScaleRank < 7"

  Where 'ScaleRank' is one of the fields in the shape file. Information on which fields are present are given in the .dbf file (which can be opened with Open Office Spreadsheet).

  Conditions can be combined, for example

      ogr2ogr output_folder 10m_lakes.shp -where "ScaleRank = 1 AND Name2 != 'Great Lakes'"
