Regression of PR885 - Flight tracks are unexpectedly clampedToGround

[t0b3]

PR #885 introduced a regression:

• flight tracks are unexpectedly clampedToGround

state before PR#885 == expected result

state after PR#885 == actual result
https://sys-map.dev.bgdi.ch/preview/bug_pb-591_3d_kml_improvments/index.html#/map?sr=3857&center=802000,5970370&camera=7.204872,47.173075,1477,-5,51,&z=17&3d&bgLayer=ch.swisstopo.swisstlm3d-karte-farbe_3d&layers=KML%7C208_Weissenstein_20_07_2024.kml

unfortunately theese two overrides ignore existing KML settings like <altitudeMode>absolute</altitudeMode> and opacity

web-mapviewer/src/modules/map/components/cesium/CesiumKMLLayer.vue

Lines 54 to 55 in 1428f4f

	alphaToApply = 0.5
	clampToGround = true

while clampToGround may make a lot of sense in some cases - for polylines it's not generally applicable ;-)

nb: does cesium parse altitudeMode well enough, doesn't it?

@t0b3 thanks for notifying us, we will have a look at it.

Hi @t0b3 ,
could you give a try on this Test link with the file you linked above? As it is a local file, it wasn't shared with us. And I couldn't test it myself

[t0b3]

@pakb while the path is now visible in the correct altitude 👍

let me share those observations:

• no terrain visible i.e. if chosen SWISSIMAGE or SWISSALTI3D
• the opacity from the KML is not respected but overriden and set to 0.5

[pakb]

Will be deployed in the next couple days on map.geo.admin.ch (I still have to found out why no background was shown in 3D)

[pakb]

@t0b3 it should now be available on https://map.geo.admin.ch if you want to test it again

[pakb]

the issue with KML is a known bug in 3D, but we sadly don't have an easy fix for that, we will be working more on 3D for the next version

@pakb thanks for the fix 😄 it works like a charm on PROD now (as you mentioned except for KML opacity)
