[Qgis-user] QGIS- How to render a raster using a field other than Value [SEC=UNCLASSIFIED]

[Inna Nogeste]

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.

Regards,
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
Damien

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.

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.
