Displaying points without image icons

[triscuit713]

I have searched the forums for the terms "point", "point cloud", "points without icons" to no avail.

I am trying to display a point cloud in google earth. When I enclose my point coordinates within point and placemark tags, the points are visualized with the pushpin icons. These points are supposed to approximate the wall of a building, and the pushpin icons do nothing to help draw that visualization.

I've tried replacing the icons with my own tiny icons, and this is better. My ideal solution would be to display points as tiny spheres. Is this possibly in Google Earth? Does anyone has a better idea?

Hi
As much as I understand, you want to draw lines. Dont you?

[triscuit713]

Not lines. I'd like to be able to generate models that look like the ones here: Human Point Cloud

except for the wall of a building instead of a person.

Unless I am misunderstanding you, and you are saying there is a way to generate a model that looks like the above with line tags somehow.

[tekgergedan]

Lines (GE terminology: paths) are done only with the Plus version or above.

Anyway...
To make those models, use combinations of icon sizes and transparencies. Do you know it? But first, of course and you already realized, the ready-made icons may not satisfy you and you may need to create a custom icon.

EDIT: Can you attach your later work (at least partially) so I can see what is really wrong and how can it be overcome?
If you mean when zooming in and out the icons mesh up and the model becomes intricate, there is no solution.

Maybe this snippet of KML will help

Code:

---

 <kml xmlns="http://earth.google.com/kml/2.0">
<Document>
<Style id="defaultStyle">
	<LabelStyle>
		<scale>0</scale>
	</LabelStyle>
	<IconStyle id="hoverIcon">
		<scale>0.3</scale>
	</IconStyle>
</Style>

<Folder>
  <name>Geograph British Isles</name>

		<Placemark>
			<name>ST7985 : The view from White Sheet Hill</name>
			<Point>
				<coordinates>-2.300017,51.563493,25</coordinates>
			</Point>
			<styleUrl>#defaultStyle</styleUrl>
		</Placemark> 

---

The important bits are the Style tags, which does a number of things, 0 scale for label so its missing (no text), 0.3 scale for Icon to make it smaller! and the styleURL you need in each placemark to tell it use the defined style,

You can also change the Icon of the placemark, the easiest way is to view use the Google Earth client to pick an icon (right clicking on the Placemark and selecting Edit) then viewing the resultant KML.

Hope that helps,

Barry

Here is a sample kmz file illustrating what I have so far.

KMZ Model of Wall

[tekgergedan]

Ops, a big file... My PC almost freeze...

Is this what you want? click

barry, you code creates an error message with me.

Not a whole KML , just enough to show the parts that need to be copy/pasted

[tekgergedan]

OK, I filled up the rest but didnt work. I'll try it out again later.

The attached KMZ file may help you to get further with your project.

• Shortened the file by using only the first 100 or so points, because the earlier file was too long to work with conveniently.
  
• Got rid of the extra tags in each point definition.
  
• Changed the icons and reduced their size.
  
  You should reduce the number of points.
  
• It currently takes WAY too long to load.
  
• The points are too dense for the Google Earth display mechanism -- just a few points would show users what you're trying to do.

Hi Price, it is true that the work include too many points. But we have to understand what the OP's problem is really. I doubt about whether your attachment is the answer.
