Hi,
If you save your raster as a "point file", you can then merge your point data
with the "raster point file". Then, you can use any field as a " z" field
and make a new raster with every field if they are numbers.
You could make a multi band raster with your data. Unfortunately, you
will need to remember the correspondence between the numbers and the field
values. Unfortunately, there is no raster data base in QGIS.

Thanks Damien,
For the purposes of the product that I'm working on the preference is for
the data to be maintained as a raster.
I've been using QGIS to test cartographic design and Map Server export
(plugin) functionalities. It's worked fine for the data I've been given
and what I've wanted to achieve except for the land use raster. I've
needed to use ArcMap for the landuse raster data.
The MapServer plugin isn't working in QGIS 2.10 Pisa but was working in
QGIS 2.8.

Inna

At this point my only suggestion is to convert the raster to polygons.
Hopefully the text is maintained.
Could you send a clipped version of the raster to confirm?
Thanks

Thanks for the suggestion. I've looked at it. Band = Band 1 (Gray) and
there is no option to select a field or even input Values.
It would be good if QGIS could have the option of selecting a field to
symbolise as this would be useful in raster data such as land use.

Ah ok the text field may cause a problem.
I don’t have any rasters with text values to test. What happens when you try
the paletted render type with text in the band rendering tab on the layer
properties dialogue?
Cheers

Hi Damien,
Thanks for your reply.
I am working with land use raster data which only has 1 band.
The values in the Value field have been attributed to a landuse (as a text
attribute) in a newly created field which is what I want symbolise. In ESRI
ArcMap, I can select whatever Value Field I want from a drop
down list of fields in the raster data. It would be good to have a similar
function in QGIS.

If your raster has more than one value field (band) it should be pretty
simple. The band rendering tab on the layer properties dialog lets you chose
the band to colour.
In the attached screen grab I have chosen band 1 using a singleband
pseudocolour render.
Hope that helps.

Value [SEC=UNCLASSIFIED]
I would like to render my raster using a field that is not the Value field. Is
it possible to do this in QGIS? This is easily done in ESRI ArcMap.
I have access to both QGIS 2.10 and QGIS 2.8.
