# 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...
# 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.

END # End of the output Projection definition ---
# 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

# 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 (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.)

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

# layers in a map.

# 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.
