I'm Qgis user from Czech Republic. We have a spatial national coordination system (Krovak system) having positive X axes pointing to the south and positive Y axes to the west. Many geographical systems have problem to display such coordination system, so usually is used transformation which gives:
X_transformed = - Y_Krovak Y_transormed = - X_Krovak The above described transformed coordination system is described in EPSG database as EPSG: 102067
To my sadness this projection was excluded from Qgis projection database starting Qgis 1.7.4. Many Czech wms servers work with this projection and I need their data. Many GIS projects are accomodated into this transformed coordination system.
To bring EPSG 102067 projection into my QGis 1.8 I override its original projection database file which is distributed with projection database file of Qgis 1.7.3 (including EPSG 102067 projection). Name of this file is srs.db
My problem is that I can not correctly geoference raster map into EPSG 102067 projection system. Above mentioned information possible could be part of the problem, or absolutely not. My attempts are resulting into georefferenced raster having height and width less than 1 meter.
Georeference points and original bmp raster could be downloaded form http://www.1progeo.cz/download.php

as a zip archive so to debug my mistake could be quite easy. Would you be so kind to help me to give me guidence how to georeference raster map correctly?
Thank you very much.
With best regards
