<p>GPXSee supports most tile server based online maps out there, but the

<p>WMTS maps are distinguished by setting the <i>type</i> attribute of the
<i>map</i> element to <code>WMTS</code>. Both the KVP and REST access methods
are supported.</p>
<p>For KVP, the <i>url</i> element represents the WMTS base URL and three
additional elements are required - <i>layer</i>, <i>style</i> and <i>set</i>
(TileMatrixSet in WMTS). An optional <i>format</i> element may be specified
defining the desired image format. If not set, <code>image/png</code> is
used.</p>

&lt;style&gt;default&lt;/style&gt;
&lt;set axis="yx"&gt;ogc:1.0:globalcrs84pixel&lt;/set&gt;
&lt;/map&gt;
</pre>
<p>For REST access, the <i>url</i> element's <i>type</i> attribute must be set
to <code>REST</code>. The URL then represents the URL of the capabilities XML
document. The three mandatory elements - <i>layer</i>, <i>style</i> and
<i>set</i> - must be present like in the KVP case. Defining the format has no
relevance for the REST access method.</p>

<p>There is one more important attribute - the <i>axis</i> attribute of the
<i>set</i> element. It specifies the axis order for the CRS used for the
tile matrix set. Technically the order should be obtainable from the CRS definition,
but in praxis many servers use the wrong order. This is why GPXSee uses <b>x,y
(lon,lat) as default</b> and if the set uses the reverse order, the <i>axis</i>
attribute must be set to <code>yx</code> in the map definition.</p>

<p>OziExplorer maps, TrekBuddy maps/atlases and GeoTIFF images are supported by
GPXSee. Supported map projections are Web Mercator, Transverse Mercator, UTM,
