[OpenLayers-Users] vector layer reprojection

[Robert Sanson]

HI

Yes, I believe the approach is to create a new layer and transform the features from the old layer and add them one by one into the new layer.

Regards,

Robert

Hi,

thanks for the response.
The situation is a bit different.

The feature are already loaded into layer and visible onto map. Now I have a combo control by which I modified SR onto map.
With this operation raster layers are reprojected correctly.
For raster layers what I have to do? I have to remove and re-add features on vector layer?

Thanks.

Giuseppe

Hi,

Try to transform all features using below code and then add features to vector layer.
Initialize and add all layers while map loading and then perform transformation operation on every feature.

geometry.transform(4326,3857);
feature.setGeometry(geometry);

vectorlayer.add(feature);

Hi all,

I have a problem with vector layer reprojection.
I have implemented a map viewer where is possible to change reference system.

If I load vector layer after that I have changed SR, this is correctly loaded. If i load vector layer and then I change SR, the raster layers are reprojected correctly, but the vector layer disappear.
Any idea?

Thanks a lot.

Giuseppe
