comment I have opened a file in QGIS from OS data and want to change the colour of some tiles
Not enough info I'm afraid. Did you download the data from the OS OpenData site? If so, which dataset? If not, what and from where?

A little more detail required please. Which OS dataset for example?

comment Calculating median elevation for local authority areas using OS Terrain 50
2800-odd ASC files? I think you'll need to break the problem down into smaller chunks. I don't have a problem gathering the ASC DEMs for one 100 km OS grid square into a VRT file, for example, or using it. You could try merging the individual ASC files into one enormous ASC file, if your system can cope with doing this. Raster -> Miscellaneous -> Merge.

comment Installing/defining custom projection Nepal Modified UTN in QGIS?
I had a quick look at this document azvoleff.com/content/2011-10-13-gis-and-gps-workshop/…. From this it appears that 'Nepal Modified UTM' could in fact be any one of three projections (depending on which meridian the projection is aligned). Is it possible to post a link to a sample of your data?

It is confusing. After giving the CRS a name and entering the Proj string press the 'plus' (+) button again.

Many thanks Ian. I'm still having problems with spacing but with this lead I should be able to sort them out.

comment Datum shift issue between OSGB1936 and WGS84
Presumably one of them is right. If on both instances you go to London with your mouse pointer and note the coordinate reported it should be easy enough to work out which. Then concentrate on getting the other one right.

comment Open LiDAR DEM of the UK with *.asc extension
ASC (*.asc) files are rasters and will load into QGIS using the "Layer -> Add Layer -> Add Raster Layer..." dialogue.

comment Is there a style sheet available for OS Open Roads layer?
The OS style files for roads in the VM District and the OM Local datasets are confusing. There are three road style files and you have to load the 'roads' shapefile three times and then style each instance using a different style file. It would help if you could add to your question above a brief description of your project.

Not as far as I know, I don't think this dataset is intended for map-making as such, but is more for distances and routing. If you want to use it with mapping I think you'd need to add one of the other OS OpenData vector datasets and style this. Or design your own styles.
