About the overlay layer called "France altimétrie GEOGRAPHICALGRIDSYSTEMS.SLOPES.MOUNTAIN": it has GetFeatureInfo functionalities based on the web service of the IGN Géoportail altimetrie REST API.<br/>
The embedMap app implements the query functionalities of the <a href="http://opengeospatial.github.io/e-learning/wms/text/operations.html#getfeatureinfo" target="_blank" >GetFeatureInfo request protocol</a>: it sends the X and Y expressed in pixels relating to the click on the map however the <a href="https://geoservices.ign.fr/documentation/services/services-geoplateforme/altimetrie" target="_blank" >Géoportail web service relating to altimetry</a> only accepts longitude and latitude expressed in decimal degrees (WGS84).</br/></br/>
This is why a match must be made before sending the request to the web service in question, this operation is carried out by the <strong>test_rest_adapter_altimetrie.php</strong> file.</br/></br/>
It is also at the level of this file that a rework of the formatting of the information returned by the Géoportail web service is done for the "text/html" format: use of a space as a thousands separator, comma rather than period as decimal separator, etc.<br/>
<hr>
The overlay layer called "France Densité INSEE.FILOSOFI.POPULATION" has GetFeatureInfo functionalities based on the INSEE.FILOSOFI.PART.PLUS.65.ANS.SECRET queryable layer (html format),<br/>
the params are written from <a target="_blank" href="https://geoservices.ign.fr/services-web-experts-economie" >from https://geoservices.ign.fr/services-web-experts-economie</a> and from <a target="_blank" href="https://data.geopf.fr/wms-v/ows?SERVICE=WMS&REQUEST=GetCapabilities&version=1.3.0" >https://data.geopf.fr/wms-v/ows?SERVICE=WMS&REQUEST=GetCapabilities&version=1.3.0</a>.<br/>
