Points

Multiple points can be defined in a FEATURE section. If multiple points are defined in the same layer, they have the same CLASS settings; for example, for colors and styles.

Coordinates are entered in the units set in the layer’s projection. In this case, it assumes the map file projection is using decimal degrees.

    LAYER
      NAME inline_stops
      TYPE POINT
      STATUS DEFAULT
      FEATURE
        POINTS
          72.36 33.82
        END
        TEXT "My House"
      END
      FEATURE
        POINTS
          69.43 35.15
          71.21 37.95
          72.02 38.60
        END
        TEXT "My Stores"
      END
      CLASS
        COLOR 0 0 250
        SYMBOL 'circle'
        SIZE 6
      END
    END

Lines

Lines are simply a list of points strung together, but the layer must be TYPE LINE instead of TYPE POINT.

    LAYER
      NAME inline_track
      TYPE LINE
      STATUS DEFAULT
      MAXSCALE 10000000
      FEATURE
        POINTS
          72.36 33.82
          70.85 34.32
          69.43 35.15
          70.82 36.08
          70.90 37.05
          71.21 37.95
        END
      END
      CLASS
        COLOR 255 10 0
        SYMBOL 'circle'
        SIZE 2
      END
    END

Polygons

Polygons are the same as the line example, just a list of points.

They require the TYPE POLYGON parameter, and the final coordinate pair needs to be the same as the first, making it a closed polygon.
