Processing toolbox: Create layer in a different projection from an existing vector layer

[brookisme]

In processing, it would be nice to be able to take an existing vector layer and create a new vector layer in a different projection. For instance starting with a layer in EPSG:4326 one could then create a new layer that is in ESPG:3857.

Note one advantage of this is that one could use the new layer and existing functionality (see #510) to then buffer in meters.

#471 is key for this issue; the user will want to know the projection of the source data to decide to use this feature. Since openlayers is doing on-the-fly reprojection, there is currently no way to tell.

Hello, in QGIS - with GDAL, I only see the option to reproject a raster layer and not vector, the above option you see doesn't show me the command how it reprojects a vector layer

Yeah, that's a QGIS quirk, it shows the command only for some processing toolbox items. This would look like:

ogr2ogr -t_srs {target_srs} new_layer.json old_layer.json
