Using QGIS, you can load the shapefile as a new layer, and Set CRS for Layer to EPSG:7405 (or better EPSG:27700). Then use Save As... to save it to another filename and EPSG:4326. Alternatively, GDAL ogr2ogr is the right tool for you. ogr2ogr -t_srs epsg:4326 -s_srs epsg:27700 dst_datasource_name src_datasource_name should deliver the data you want, ...

You can create a local CRS with an oblique mercator projection, and transform the data with gdalwarp and gdal_translate into it. See my advice here: Using customized Coordinate System for Archaeological site data This should work with 16-bit or grayscale data the same way. Paletted colours shoud be expanded to RGBA in advance. UPDATE Using QGIS, ...

Rather simple method is to write a new world file (.tfw) which contains rotation parameters. You can make such with OpenOffice Calc, for example. If you have a GeoTIFF file which contains reoreferencing info as stored into the image tag you must clear the geotiff tags and create a baseline tiff to start with. It can be done with gdal_translate: ...

Using QGIS 2.6.1 (and probably some previous versions as well) Go to "Processing toolbox" and search for "Reproject layer" under QGIS geoalgorithms, Select the tool and right click to open contextual menu, Select the "Ëxecute as batch process" option Select each one of your "input layer", "Target CRS" and "Reprojected layer name" Click ...

If you have GDAL, you can reproject the png with: galwarp -s_srs epsg:28992 -t_srs epsg:4326 source.png dest.tif If you want a png file as result, you have to use gdal_translate in a second step: gdal_translate -of PNG test.tif dest.tif dest.png

I asked internally here at Pitney Bowes and got this reply: You should be able to do it by copying the gsb file to MapInfo Pro folder end editing the NTv2.xml file. You will need to add this transformation to the NTv2.xml file: <NTv2Conversion> <Description>NTv2 for Switzerland from CH1903 to CH1903+</Description> ...

If I understood the surveyor's directions correctly, you should be able to make a custom projected coordinate reference system for the CAD data. Let's say that standard UTM coordinates are calculated like this: e = fe + k0 * x n = fn + k0 * y where e = UTM easting, n = UTM northing, k0 = 0.9996, fe = 500000.0, fn = 0.0, and x and y are the ...

This may help of even answer your question. I don't know how accurate you have to be in your maps but georeferencing should get you close. The how to is referencing an older version of arc but it should be basically the same as performing this in 10.2 ...

If you digitized the vector layer based on the raster but had a wrong CRS specified for the vector layer, the easiest option should be to simply overwrite the Shapefile's .prj file with the correct CRS information.
