I am working in QGIS 1.8.0 Lisbosa. Currently I am trying to georeference a building blueprint in a .TIF format to a Google Streets layer. After selecting four points (the corners of the building), I run the function (Thin Plate Spline - Cubic Spline) with a target SRS of UTM Zone 18N (EPSG: 3725). However, the results don't show up on the map. When I click zoom to layer, the screenview doesn't move. So either it isn't working, or the results are invisible.

Any idea what I'm doing wrong here? I know I've Georeferenced similar blueprints before, but I'm not sure what I'm doing differently.

If you have Google Street Layer from Openlayers plugin as background, your project CRS and that of the geotiff must be EPSG:3875 when georeferencing.

You can reproject the result later into any other CRS.
