a Map that doesn&#8217;t use base layers currently the map author has to set
the upper and lower bounds on the layers themselves. The defaults for layers
are 0 to Infinity, but this can certainly be changed for every layer so that
the map displays nothing below 10000 &nbsp;or above 500000 for example. This
doesn&#8217;t stop the user from zooming further in either direction, but with
no data it&#8217;s kind of pointless. There is no easily configurable limit

The author can zoom in and set the default view using this link. The bounds on
