[MultiGeometry] ge

[Laurent]

Hi,

I want to deserialize a kml file with KmlLib (Kml library, version C#
(Aug 25, 2011)), but it's don't work.
The deserialisation are ok, but when I watch my object, I don't get
some properties of this object.
By example, in my kml file, I have these sections :
<Folder>
<name>02 - Aisne</name>
<Placemark>
<name>Limites administratives</name>
<styleUrl>#khStyle2676</styleUrl>
<MultiGeometry>
<extrude>1</extrude>
<LineString>
<extrude>1</extrude>
<coordinates>
4.12644497,49.67821369000001,0 4.12623943,49.67472240000001,0
4.12484074,49.65061485,0 4.11720479,49.64152870000001,0 4.1...
</coordinates>
</LineString>
<LineString>
<extrude>1</extrude>
<coordinates>
2.99020203,49.21067358,0
2.99171255,49.2...2.99020203,49.21067358,0
</coordinates>
</LineString>
</MultiGeometry>
</Placemark>
</Folder>
I want to get coordinates's section, but they are no visible in
deserialised object, no properties match.
Somebody, have an idea? There something, that I don't understand ?
This Kml lib's version is beta, and if yes, how I get another rc
version ?

Thanks a lot

Hi Michael,

Thank's for your examples, you use the same library than me ? (same version). Another question, kmlLib (version C++) look's more complete than KmlLib (version C#), it's really ?

I don't get the coordinates values in Multigeometry/LineString's Tags, because the deserialised object don't contains this properties.

I have the same problem, when I like get value coordinates in Placemark tag ?

Example :<Point id="khPoint933">

          <coordinates>-0.3600000143051101,49.18444444444445,0</coordinates>

        </Point>

In attachment, I have put my kml file, could you test the obtention of coordinates in Multigeometry tags ?

Have you an idea ?

Sincerely,

Laurent BROUCK

I don't know anything about the C# version. Can't help you there.

I've attached a diff that modifies
examples/helloworld/printgeometry.cc to print coordinates of
LineStrings and Points when it sees them. For example:

$ echo "<Placemark><Point><coordinates>0,1,2
3,4,5</coordinates></Point></Placemark>" > /tmp/x.kml &&
./examples/helloworld/printgeometry /tmp/x.kml
Found a Point
coordinates:
<coordinates>0,1,2
3,4,5
</coordinates>

Thank Michael for your help, I will watch more this examples.

In your, my kml file is correct ?

Hello Michael,

I have spend many times about this problem, and he is dont't solve :(

I thinl, yout lib in C++ is more complete than C# version, for example, I didn't find the function get_geometry_array_size.

I have no more idea, only post a news comments on the forum !

Best suggestion is to contact the maintainer of the C# version.
