# 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 parameters can be defined in two ways...
        # This is the traditional PROJ definition of Lambert Azimuthal Equal-Area
        # projection for the Continental U.S.
        #  "proj=laea"
        #  "ellps=clrk66"
        #  "lat_0=45"
        #  "lon_0=-100"
        # Alternatively, you can specify an EPSG code.
        # This is the EPSG code for Lambert Azimuthal Equal-Area
        # projection for the U.S.

  # The web object is defined at the level below the map object.  All
  # web-related parameters (I interchange "parameters" and "keyword/value
  # pairs" quite frequently, sorry about that) are defined in this object.
        IMAGEPATH "/ms4w/tmp/"
        IMAGEURL  "/tmp/"

  # 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.

        # Here's an example of the input projection definition.
        # EPSG:4326 is code for geographic (latlong) projection
        # using the WGS84 datum.
        # PROJECTION objects within the LAYER object define the input
        # projection--this is the native projection of your data.

        # 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"

        # Just like CLASSITEM, LABELITEM defines the database attribute that you
        # will be using to draw labels.  In this case, the values of the attribute
        # "STATE" will be used to label the states polygons.
        LABELITEM    "STATE"

        # The class object is defined within the layer object.  You can define as
        # many classes as you need.
          NAME 'States'
          EXPRESSION 'land'

          # There are styles in a class, just like there are classes in a layer,
          # just like there are layers in a map.  You can define multiple styles in
          # a class just as you can define multiple classes in a layer and multiple
          # layers in a map.
                COLOR      232 232 232

          # There can be labels in a class, just like there are classes in a layer,
          # just like there are layers in a map.  You can define multiple labels in
          # a class just as you can define multiple classes in a layer and multiple
          # layers in a map.
          # MapServer has a very flexible labeling system.  With that flexibility
          # comes complexity, specially when using truetype fonts.  Please read
          # through the LABEL section of the MapServer map file documentation at
          # http://www.mapserver.org/mapfile for more information.

  # 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 can read and display bitmapped (like GIFs), RGB/A (true
  # color), and multispectral (images with more than 3 bands, like raw LandSat
  # images) rasters.

  # MapServer can consume layers from other map servers as
  # long as those servers are Web Mapping Service (WMS) providers.  WMS is a
  # web service specification from Open Geospatial Consortium (OGC) and is
  # intended to be an interoperability standard for web mapping applications.
  # This allows us to display layers we don't usually have (or can't store in
  # our computers due to space limitations).  The downside is that we have to
  # depend on some other server to display our layer, and that server can be
  # down when you really need it.  The cool thing is that NASA has a WMS server
  # that serves out MODIS satellite maps for the whole world--try storing
  # those datasets on your computer!  Read more about the service at
