QGIS' georeferencer layer doesn't appear?

Question

I use QGIS 1.8.0 for Linux, and I want to draw roads manually on the map.

enter image description here

So according some tutorials, I use Raster>Geoferencer>Geoferencer to import a bitmap image including roads, and set Geoferencer like this screenshot.

However, after "Start geoferencing", the Geoferencer layer didn't appear on the map. Just like this:

enter image description here

I've tried move the reference layer to top and toggle "update drawing order" but it doesn't work.

What should I do?

Which coordinate reference systems (Layer/Project CRS) are you using? — q9f, Jan 04 '13 at 10:14
TWD67, and all of my layer set as that(including georeferencer) — kuanyui, Jan 04 '13 at 11:02

I had the same problem and found that following the instructions at OpenLayers Plugin Error: latitude or longitude exceeded limits worked. They are:

set the project CRS to EPSG:3857
make sure on-the-fly-projection is enabled
add the background openlayers map layer you want load other stuff that might have other layer CRS, like WGS84 in lat/lon degrees
save the project

After this georeferencing the image map with CRS EPSG:3857 worked. I wish I knew why.

This was the only thing that worked for me too, so weird... – kory Oct 08 '18 at 13:06 — kory, Oct 08 '18 at 13:06

Look for Settings -> Options, CRS Tab

under CRS for new Layer, you should activate Ask for CRS. and choose your custom CRS.

Standard is EPSG:4326, and the coordinates of your tif are most probably outside the allowed bounds of +-180°/90° of lon/lat coordinates.

All of my layer is TWD67-TM2(a common CRS used in Taiwan), including groreferencer. But it doesn't work when georefrencing. – kuanyui Jan 04 '13 at 11:09
Qgis Master offers EPSG:3827 and 3828 for that CRS. If you don't want to use that, you can use current GDAL to reproject the tif to a CRS known in your Qgis Lisboa. – AndreJ Jan 04 '13 at 11:17
Have tried, but doesn't work :( – kuanyui Jan 04 '13 at 11:22
Your screenshot shows EPSG:3857 as project CRS. If you have grabbed the georeference points from the screen, you have to set the target CRS also to EPSG:3857. – AndreJ Dec 16 '13 at 14:23

Try converting the image to be referenced to a jpg instead of a bitmap, it worked for me.
