KML opens with the wrong geoposition - kml

I'm trying to create a map of the Stockholm's subway lines in Fusional Tables.
In the Fusion Tables I created a map with geo each station:
https://www.google.com/fusiontables/DataSource?docid=1K7F2DMY5JBA6ZQOH8a1a4dQjwxoksRDMJ3-wPEg#map:id=3
I want to connect them to the polyline.
Options to create polylines and way in the tables there, or they are very well hidden.
So I created this KML file and loaded into tables:

What is my fault? Is there some other way create polylines in tables between objects?

You have the coordinates backwards. KML coordinates are longitude,latitude,altitude.

LabelStyle.... Why won't this code produce red font on half size labels?

I'm doing a proof-of-concept map. Goal is half sized labels, with red font, and no icon. I've tried everything, even copy pasting from the google KML reference manuals and many examples posted here. What am I missing? I'm trying to display the map in both Google's "My maps" and also as a called data file at the browser utility gmap4. The test map should show four labels with Google streetmap of Pennsylvania for a baselayer...... Thanks for any help.

The KML syntax includes a number of tags that are not supported by plain Google maps (my map) or by sotfware based on the Google map API. One of the non-supported tags is .
See: https://developers.google.com/maps/documentation/javascript/kmllayer#supported-elements
To make a label with no icon try making a transparent icon.

KML icons on every waypoint

I want to export telephone poles and cables out of our database into a KML file for Google Earth.
For every node we have an array of poles, the cables are always connected towards the next pole in the array.
An export making simple paths seems to be easy enough. But these paths just show a path, they don't show every waypoint (telephone pole).
This is an example in Google Maps what I want to achieve in .kml
If you want paths and points for each of the poles (aka waypoints) then you need your KML to include not only the line segments separate points for each of the positions of the poles.
Your KML will need to be structured like this where poleSyle will have an IconStyle with the icon you want for the points and lineStyle will be a thick green line
<kml xmlns="http://www.opengis.net/kml/2.2">
<Document>
<Style id="poleStyle">
...
</Style>
<Style id="lineStyle">
...
</Style>
<Placemark>

<Placemark>

<description>address pole1</description>
<styleUrl>#poleStyle</styleUrl>
<Point>
<coordinates>...</coordinates>
</Point>
</Placemark>
...

</kml>
If you don't want or need a unique name or description for every point then you can combine the points in a single Placemark inside a MultiGeometry like this:
<Placemark>
<styleUrl>#poleStyle</styleUrl>
<MultiGeometry>
<Point>
<coordinates>...</coordinates>
</Point>
<Point>
<coordinates>...</coordinates>
</Point>
</MultiGeometry>

Multiple icons in one KML Placemark

I have some symbols that I want to add to a KML file (for Google Earth). However, my symbols consist of multiple icons overlayed on top of each other. For other maps that I use I simply draw the icons on top of each other and control the selection/right click actions so that the user only sees it as one object, but in Google Earth if I add each overlayed icon as a separate placemark the user sees multiple objects when they click on it. Is there a way to add a single placemark in kml with multiple icons?
I wanted to do something like this:

where I just have multiple <Icon> tags (or multiple <IconStyle> tags). However, looking at the schema this is not valid and I tried it anyways and it only picks the last one.
Is this even possible or will I need to dynamically create rolled up icons in code and include those in my .kmz file?
A KML placemark can only have one icon image. You will need to combine (roll up) your icons into a single image and then apply that to the placemark.

Placemarks lookat range ignored

I'm using this KML file (lets call it load.kml)
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://earth.google.com/kml/2.1">
<Document>
<NetworkLink>

To point Google Earth to a kml file (lets call it test.kml). When I load test.kml regularly (without using load.kml) the range I set works correctly (the zoom level is how I set it).
But when test.kml gets loaded using load.kml the range is incorrect. The placemark zooms in really far and ignores the range I set in the test.kml file.
Is there something overriding the range inside load.kml?
Example of test.kml:

There are a few undocumented differences when you load KML directly as opposed to via a NetworkLink.
When you load the KML via the NetworLink it looks for a LookAt or Camera in the outermost element which is the Document in test.kml file.
You can either 1) copy/move the <LookAt> from the Placemark to the parent Document element in test.kml or 2) copy the <LookAt> and insert into the NetworkLink in load.kml and make flyToView=0.
If the target KML has timestamps then the behavior via Networklinks is different then loading it directly. See related issue.

delaying balloon component in a KML code

I have just started to learn how to manipulate the KML files. here is a problem that I do not know how to overcome.... I created a polygon and added a description to be shown as a balloon, but it appears as soon as Google Earth starts working before the polygon can be seen. what I want is to show the balloon from a specific distance where the polygon appears(for example in the range distance of LookAt element).
anybody knows how to manage that?
my code follows:
<?xml version="1.0" encoding="UTF-8"?>

Normally you can skip rendering the polygon until you get "close" enough to it as defined by a Region element which is determined by calculating when a given area maps to a min or max # of pixels.
Also, the <gx:balloonVisibility> tag forces the description balloon to appear when the KML is loaded regardless of whether Region is active. Adding a Region direct in the KML still shows the popup balloon.
To do what you want to do, you must wrap the KML file with a second KML file with a NetworkLink with a Region that loads the seconds KML only when the region is active (aka close enough) at which time the description is displayed along with the polygon.

And target.kml file contains the original KML you gave:
<?xml version="1.0" encoding="ISO-8859-1"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<Placemark>
<name>Stadium</name>
...
</Placemark>
</kml>
You can change the distance the feature + balloon appears by adjusting the minLodPixels value and/or the size of the region. At present the feature will display when the region defined by area surrounding the polygon is at least 128 pixels on the screen. Change to 32 or 64 and/or make the region area larger to make it appear quicker.
Note Google Earth client doesn't give you a tool to edit or even see the Region bounding boxes on the map so debugging this is tricky. You can paste your KML into this tool to generate KML making the Region bounding area visible. This helps to debug Regions more easily.
