# Example 1.2

## Static Map with Two Layers

As in the first example, this image was generated by linking the source of the <img> tag to this URL: https://demo.mapserver.org/cgi-bin/mapserv?map=/osgeo/mapserver/tutorial/htdocs/example1-2.map&layer=states_poly&layer=states_line&mode=map. This is how most of the examples in this section work.

Anyway, you’ll notice that the map here is the same as the first example. Yes, but the mapfile is different. Have a look.

This is what the mapfile looks like: Example1-2.map

### MapFile Structure

The mapfile structure, by objects, looks like this:

               MAP
          LAYER-|-LAYER
       CLASS-|     |-CLASS
    STYLE-|           |-STYLE

Here we split the original layer into two layers. The first layer is still a polygon layer but the STYLE object no longer has OUTLINECOLOR, such as:

    LAYER
      ...
      TYPE         POLYGON
      ...
      CLASS
        NAME       "States"
        STYLE
          COLOR    232 232 232
        END
      END
    END

The second layer is similar to the first except that the TYPE is changed to LINE and the COLOR in the STYLE is changed to the same color as the OUTLINECOLOR in the first example. This produces the same image as the first one.

    LAYER
      ...
      TYPE         LINE
      CLASS
        NAME       "State Boundary"
        STYLE
          COLOR    32 32 32
        END
      END
    END

### So, why do it this way?

If we continue to add layers on top of the states layer, the outline will most likely be covered up by these other layers. To still see the state boundaries after we add these other layers, we have to separate the states boundary line layer from the states polygon layer and put it on top of the other other layers. There is order in how we define/add layers and you’ll see it clearly as we proceed in this section.
