He can use a command in AutoCAD called ALIGN to geo-reference his existing drawing. He will need to copy in his existing work into the OS dwg you have sent him. He can then select all his work, use and the ALIGN command to line his drawing up with the OS data. This will only work if there are a couple of reference points in his existing drawing that ...

You've got so many lat-long points to georeference it probably doesnt matter much what you use. I just created eight points at some graticule grid points and warped the raster to EPSG:4326 (lat-long). The results look pretty good. If what you really wanted to do was assign the correct CRS of the original image to it then you'd have to work out what the ...

It is Georeferencing that I would use to try and do this. I have done that for Australian maps from the 19th century related to family history. If you try, and get stuck, then just ask a more focussed question about precisely where you get stuck.

Your assumption is right, you need the correct values for the corner coordinates. Since the source image is slightly larger than the Earth, you can not simply reproject the corner coordinates. You may use a different approach: According to the project site, the 5500x5500pix data is providing a 2km resolution on the center. So the extent from the center is ...

Archaeological digs usually use a localized grid, that while it may be originally based off a national grid, is customized to fit the local demands. these grids might be orientated to fit the archaeological architecture, topography, and sometimes to force only positive values of east/north in order to make measurements easier. Georeferencing this raster ...

You should use something like: gdal_translate -of GTiff zoom13.mbtiles export.tiff The reason for the -of GTiff part is that the default output is TIFF, with external georeferencing, rather than GeoTIFF. See http://www.gdal.org/frmt_gtiff.html If you want to rebuild the overviews (similar to what you probably have in mbtiles), gdaladdo will probably help: ...

I think it is a duplicate of How to georeference a dxf?,How to georeference a vector layer with control points? 1) Using the limits of the Carta Administrativa Oficial de Portugal (shapefile, the projection is EPSG:3763 (ETRS89 / Portugal TM06)) you can georeference the original pdf file 2) To georeference a shapefile (it is better to transform your dxf ...

You can use affine transformation plugin if you know the offset of the vectors, DXF have to be converted to QGIS editable format (e.g. shapefile) You can use LibreCAD to translate the DXF file You can use SurveyingCalculation plugin to calculate transformation parameters from coordinates given in source and target CRS

This Google Earth support page explains how to achieve this. Basically you need to make sure that your imagery is on WGS 1984 projection and follow File>Import steps. You may be asked to create a Super Layer, which will be a KMZ version of your imagery. Another option is to use Layer to KML tool in ArcGIS. You need to be careful as setting the "Output Image ...
