# Viewer with Scale Limits

The map client configuration

The ViewContext configuration

## Further notes

By using the map properites "minScale" and "maxScale" you can define the map viewer's scale limits. In the following example it is not possible to zoom to a zoom level that is below 1:500:

    <maxScale>500</maxScale>

There might be applications which require a specific layer to be displayed within a limited scale range. In the following example only one layer at a scale that is larger than 1:100,000 is queried:

    <Layer queryable="1">
      <Server service="OGC:WMS" version="1.1.1">
        <OnlineResource xlink:href="http://www2.demis.nl/wms/wms.asp?wms=WorldMap" />
      </Server>
          <Name>Hillshading</Name>
          <Title>Hillshading</Title>
      <SRS>EPSG:4326</SRS>
      <Extension>
        <le:Extension xmlns="">
          <minScale>100000000</minScale>
          <opacity>0.6</opacity>
        </le:Extension>
      </Extension>
    </Layer>
