[OpenLayers-Users] Highlighting Feature on KML Layer

[Jerome A. Wendell]

Phil,

 

Thank you very much for your reply.  Is there another format for vector
layers that you would recommend?  I do have the option to possibly create
the data in another format.

 

Thanks,

 

Jerome

I am new to web mapping and to OpenLayers.  I have created a basic map that
has a base layer and a KML vector layer.  The features in the KML vector
layer have several attributes.  When opening my map, is it possible to
highlight and zoom to a specific feature in the KML vector layer based on
one of the attributes?


You will note that google isnt good about providing that functionality
themselves in their products. KML is a very flexible format. You can define
attributes for a featureset in the set header and then provide just the data
for the feature ( as you would for a "normal" layer), but you can also have
attribute and data for each feature (ie each feature could have different
attributes). Furthermore the KML could just be a network link.

In short, I dont think it is implemented in OL but maybe others would prove
me wrong. If you are stuck using KML vector files, then I think you will
need custom code to pick your way through a loaded KML layer feature
entries. If you have option of not using KML than I would strongly consider
it. If your data is in say geoserver then you can create a WFS kml link to
view in GE from your web application but using KML directly is slow and
limited.
