# The annotated map file (sort of)

#
# MapServer map file uses the pound sign (#) to denote the start of a line
# comment--each line that needs to be commented has to be prepended with a "#".
#
# Map files begin with MAP keyword to signify the start of the map object.
# Well, the entire map file is THE map object.  Enclosed between MAP and END
# at the very bottom of this map file, are keyword/value pairs and other
# objects.

  # The projection object is typically used within the map and the layer
  # objects. You only define it once within the map object and this definition
  # becomes your output projection--MapServer will render your maps in this
  # projection.  You also use the projection object within the layer object to
  # define your input projection.  Your layers can be in different
  # projections--MapServer will reproject them into your output projection.
  # If no projection is defined within the layer object, MapServer assumes
  # your input projection is the same as your output projection.  This is not
  # a required object unless you're creating a map file that supports one of
  # the OGC interoperability web services specifications (WMS/WFS/WCS).

  # This is the output PROJECTION definition ------
  PROJECTION
    # Projection parameters can be defined in two ways...

    # projection for the Continental U.S.

  # Layer objects are defined beneath the map object.  You need at least one
  # layer defined in your map file before you can display a map...  You can
  # define as many layers as you'd like although a limit is typically hard-coded
  # in map.h in the MapServer source.  The default limit is set at 100.  You'd
  # have to have a very specialized application to need more than 100 layers in
  # your application.

    # CLASSITEM defines the non-spatial attribute that you will be using to
    # separate a layer into classes.  This attribute will be in the DBF file
    # of your shapefile (it will be different for each data format).  In this
    # example the shapefile states_ugl has an associated database
    # (states_ugl.dbf) that contains an attribute called "CLASS".  You will be
    # using two values in the CLASS attribute to separate the classes (also
    # called themes) used in this layer--land and water.  CLASSITEM is used in
    # association with the EXPRESSION parameter in the CLASS object.  See below.
    CLASSITEM    "CLASS"

    # The class object is defined within the layer object.  You can define as
    # many classes as you need (well, there are limits as with layers, but it's
    # senseless to define more than ten on a "normal" layer.  There are
    # situations, however, where you might have to do it.)

      NAME 'States'
      EXPRESSION 'land'

      # There are styles in a class, just like there are classes in a layer,

  # In addition to vector data (shapefiles are vector data), MapServer supports
  # a host of raster formats.  In GIS world, one of the most common raster
  # formats is GeoTIFF, a TIFF image with geospatial headers.  MapServer also
  # supports JPEG, PNG, GIF, and other common formats.  Other raster formats
  # supported by MapServer include ESRI Arc/Info grid, HDF and HDF-EOS, NetCDF,
  # Generic raster binaries, OGC Web Map Service (WMS) layers, etc.  Pretty much
  # any raster format you can think of is probably supported, thanks to the
  # impressive Geospatial Data Abstraction Library (GDAL, pronounced "GOODALL"
  # or GOODLE?).  More information on GDAL is available at http://www.gdal.org.
  #
  # MapServer 4.x can read and display bitmapped (like GIFs), RGB/A (true
  # color), and multispectral (images with more than 3 bands, like raw LandSat
  # images) rasters.
