EPSG:24378 Kalianpur 1975 / India I should be the local CRS in the region you mentioned. The extent seems to fit to that: To get this picture using QGIS, create these text files: E N 73.4775 34.3629 and Easting Northing 3250193.00 1115573.00 3249214.00 1111220.00 Load each into QGIS as Delimited Text File, with blank as delimiter and setting CRS to ...

I think this is a good question and just wanted to add a more explicit answer aimed directly to the original phrasing of the question. No, reprojecting a shapefile does not only change the prj file, it changes both the prj file and the main shapefile contents (the .shp file). The reason being, as demonstrated by @csw, reprojecting a shapefile has to ...

For the Mercator projection, the extent can not reach North and South pole for mathematical reasons. The standard Google and Openstreetmap mercator projection is limited to 85.011° North and South to get a square map. See http://wiki.openstreetmap.org/wiki/Slippy_map_tilenames#X_and_Y for explanation. Using EPSG:3857, the extent of a map is ...

I discribed a workflow to get aeqd maps using a sphere instead of an ellipsoid here: Manipulating Azimuthal Equidistant Projections in QGIS If you only want to have 180°, I suggest clipping the resulting picture with a polygon in aeqd projection would be the solution. For a bearing from -45° to 135° from the center of projection at 7E 51N, the clipping ...

I suggest to change your settings under Settings -> Options, CRS, CRS for new layers to Prompt for CRS You can rightclick on every layer -> Set CRS for Layer and check that your rail data has the custom CRS, but road data another CRS as stated for your library. If the data comes as shapefiles, they should have the correct .prj file with projection ...

I'm not sure where you found the code epsg:4277 from but it is a representation of the OS national grid in degrees (if I'm reading the EPSG file correctly) the much more common EPSG code is EPSG:27700 which is measured in meters.
