<div dir="ltr"><div><br></div><div>Hi Dennis,</div><div><br></div><div>I've done exactly what you describe in GM3. Slightly different than Duck's method because like you I serve the DEM from MapServer and in GM3 you can still use MapServer directly as a source.</div><div><br></div><div>The steps are:</div><div><br></div><div>- create a mapfile for the DEM source, and list it as a map source in the Mapbook</div><div>- the mapfile is configured for WMS GetInfo, STATUS is ON, and (optional) there is no STYLE defined</div><div>
- the Mapbook map source should have an identify template so that any results are visible to the user
<br></div><div>- user will get a result from the DEM whenever they click within the bounds of the DEM</div><div><br></div><div>Here is the basic Mapbook map source if it's helpful:</div><div><br></div><div><map-source name=" bare_earth
" type="mapserver" tiled="false"><br><div style="margin-left:40px"><file>bare_earth</file><br> <layer name="bare_earth" status="on"><br></div><div style="margin-left:40px"><div style="margin-left:40px"> <template name="identify"><![CDATA[<br></div></div><div style="margin-left:40px"><div style="margin-left:40px"><div style="margin-left:40px"> <div class="result-item"><br></div></div></div><div style="margin-left:40px"><div style="margin-left:40px"><div style="margin-left:40px"><div style="margin-left:40px"> <div class="result-title" style="background-color: #F5DEB3; padding: 5px; "></div><div style="margin-left:40px">LiDAR Spot Elevation</div><div style="margin-left:40px"></div><br> <b>Bare Earth NAVD88 Elevation: </b> {{ properties.value_0 }}<br><br></div></div></div></div><div style="margin-left:40px"><div style="margin-left:40px"><div style="margin-left:40px"> </div><br> ]]></div></div></div><div style="margin-left:40px"><div style="margin-left:40px"></template><br></div></div><div style="margin-left:40px"> </layer><br> <param name="FORMAT" value="image/png;bits=8"/><br></div> </map-source> </div><br><div>I like having no style defined for the web service so that the DEM itself is not visible, and the elevation result is a "bonus" result that returns along with whatever results are relevant for the clicked location.</div><div><br></div><div>I haven't tried the
type="wms"
method of access for the DEM, but can set up a test if needed. I think with status="on" in the map source you might not need the layer to be listed in the catalog?, but without testing I'm not sure...</div><div><br></div><div>best,</div><div>Tanya</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Wed, Jan 21, 2026 at 9:13 AM Dan Little via GeoMoose-users <<a href="mailto:geomoose-users@lists.osgeo.org">geomoose-users@lists.osgeo.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Hi Dennis!</div><div><br></div><div>Sorry for the slow response here.
