[mapserver-users] multiple map layers with different scales

[Fawcett, David (MPCA)]

Create a layer for each data set.  

Use Layer MAXSCALEDENOM and MINSCALEDENOM to define when the layer should be drawn.  http://mapserver.org/mapfile/layer.html

I have multiple map layers with different scales.
 
For example,
+---------------------------------------------+
|  A    +-----------------------------+          |
|        | B                             +----------+ | 
|        |                                | C           |  |
|        |                                +----------+ |
|        |                                      |           |
|        +----------------------------+           |
+---------------------------------------------+

A   1:1000 
B   1:500
C   1:100

How can I setup them in mapserver, so that I can render the map with
different detail.

For example:

given a scale value from 1:100
The map is rendered with:
+---------------------------------------------+
|  A    +-----------------------------+          |
|        | B                             +----------+ | 
|        |                                | C           |  |
|        |                                +----------+ |
|        |                                      |           |
|        +----------------------------+           |
+---------------------------------------------+


given a scale value from 1:200
The map is rendered with:
+---------------------------------------------+
|  A    +-----------------------------+          |
|        | B                                   |           | 
|        |                                      |           |
|        |                                      |           |
|        |                                      |           |
|        +----------------------------+           |
+---------------------------------------------+

given a scale value from 1:700
The map is rendered with:
+---------------------------------------------+
|  A                                                       |
|                                                           | 
|                                                           |
|                                                           |
|                                                           |
|                                                           |
+---------------------------------------------+
 
Is that possible?
