GML not rendered correctly

[antoniolocandro]

Expected behavior and actual behavior.

*** Already reported in QGIS but they suggested this is really a GDAL thing to be investigated, sorry I don't have more technical skills to do it completely by myself ***

If I add the following attached file the GML should all be over the North Atlantic between USA and Europe, however when point features use the following root element aixm:ElevatedPoint (<aixm:AeronauticalGroundLight gml:id="uuid.9481f274-f05b-4c00-9017-eae75d33c45b">) it is not rendered correctly as opposed to if used aixm:Point (<aixm:DesignatedPoint gml:id="uuid.2fea81e6-023b-4069-b8cd-2ab96da27862">)

Steps to reproduce the problem.

I am using the following file loaded in QGIS

EA_AIP_DS_FULL_20170701.zip

I add the filed attached before and will select only the following layers as shown per the image
layers_for_test

You will notice the following view on the map canvas of QGIS

I will start with the following two point layers for review

I have concluded the following

-> render correctly (check layer = DesignatedPoint)

<aixm:Point srsName="urn:ogc:def:crs:EPSG::4326" gml:id="pBOR10">
gml:pos51.529284 -33.555661</gml:pos>
<aixm:horizontalAccuracy xsi:nil="true" nilReason="unknown"/>
</aixm:Point>

-> render incorrectly (check layer = AeronauticalGroundLight )

<aixm:ElevatedPoint srsName="urn:ogc:def:crs:EPSG::4326" gml:id="ID_343">
gml:pos55.36666666666667 -33.983333333333334</gml:pos>
</aixm:ElevatedPoint>

So why does QGIS/GDAL handles improperly the second case, is like it doesn't take into consideration the axis order for it which is lat,lon for EPSG:4326, I suppose because it is a specialization class from the aviation schema, but it is supposed to be inheriting properties from the GML, here is the definition for it which mentions "This is a specialization of the Point class and it inherits all attributes and associations of that class." which in turn the Point class "This is a specialization of the GM_Point class and it inherits all attributes and associations of that class."

All of this is supposed to be based on ISO 19107
http://www.aixm.aero/sites/aixm.aero/files/imce/AIXM511HTML/AIXM/Class_ElevatedPoint.html?menu=open

So to sum up the layer AeronauticalGroundLight has the axis reversed like it can't honor the axis order and it uses the AIXM:ElevatedPoint, the layer DesignatedPoint has the axis correct but uses AIXM:Point

Operating system

Confirmed fix! Thanks you this will make it possible to use it for aviation even more

I have one more issue

render incorrectly (check layer = Airspace )

the following feature identifier

<aixm:Airspace gml:id="uuid.21a13c9f-a8ff-4fdd-9aaa-5dbfd91514b8">
<gml:identifier codeSpace="urn:uuid:"
>21a13c9f-a8ff-4fdd-9aaa-5dbfd91514b8</gml:identifier>
...
<aixm:Surface srsName="urn:ogc:def:crs:EPSG::4326"
gml:id="ID_240">
gml:patches
gml:PolygonPatch
gml:exterior
gml:Ring
gml:curveMember
<gml:Curve gml:id="ID_241">
gml:segments
<gml:CircleByCenterPoint numArc="1">
gml:posList52.36666666666667 -22.1</gml:posList>
<gml:radius uom="NM">15.0</gml:radius>
</gml:CircleByCenterPoint>
</gml:segments>
</gml:Curve>
</gml:curveMember>
</gml:Ring>
</gml:exterior>
</gml:PolygonPatch>
</gml:patches>
<aixm:horizontalAccuracy uom="KM"
>2.0</aixm:horizontalAccuracy>
</aixm:Surface>

Axis is inverted for this, seems the Circle by Center point doesn't honor also the axis order maybe is something similar to the aixm:ElevatedPoint?
