Re: [Qgis-user] Using OS Raster Data in QGIS

2022-06-25 Thread Patrick Dunford via Qgis-user 
Generic rules for raster image files is there will be at least two or 
three files for each tile:


* The raster itself

* The world file which has a similar extension usually ending with a W 
e.g. JGW for a JPEG tile


* One or more XML files

The world file contains the coordinates and pixel size information, the 
XML file(s) will contain the CRS information.


If these files are missing Qgis will display a ? at the end of the file 
name when attempting to load it.


You can set the CRS in Qgis to compensate for a missing XML file CRS, 
but the world file is essential otherwise the raster will be loaded at 
the origin coordinates (0,0) of whatever CRS is being used.

Hi, I used QGIS about 4 years ago to produce maps for 1:25,000 and 
1:50,000 OS maps, I feel a fool now, but I am struggling to get QGIS 
2.18.28 to upload the files in the Raster (miscellaneous) section as I 
used to do. I just get all the files not being recognised.


I have downloaded the latest QGIS 3.8, but do not understand this one 
at all.


Could someone help me with a step by step loading of the OS raster 
data into the QGIS system so that I can produce some maps please?


I also have the Geo referencing and sea tiles but again QGIS does not 
seem to like them. I am using EPSG:27700


Thank You

 Rasters sometimes have more than one file with the same name for each raster. 
A good rule of thumb is to open the largest file. The documentation for adding 
rasters to a project will help you with the procedure. The link below is to the 
current Long Term Release documentation 3.22. 3.8 is quite old. 
https://docs.qgis.org/3.22/en/docs/training_manual/rasters/index.html

You may also be using vector data from Ordinance Survey, so from the Data 
Source Manager click on vector on the left and select Directory for source type 
and UK.NTF2 from type and then navigate to your data file.

Nicolas, everyone,

Sorry to top post here but I'm not sure where to start below.

What about just using the various drawing tools on the print layout?
Arrows can be added, annotation, polylines, that sort of thing?  Of course
it's not in the original data / layers, but is that important?
