Hi Craig,
Thanks to your precise instructions I've been able to import the data
correctly. :-)
I now have another issue, how to display continuous colors.
I went to Properties and fiddled with both Graduated Symbol and
Continuous Colors. The results appear in the attached pics, and look
terrible and useless. I don't want a symbol for each pixel, but a
simple color code. An example of what I'm trying to achieve is also
attached.
I also noted that the transparency cursor does not do anything.
I guess I miss something important here.
Can you please help?
Thanks,
Chris
Hi Chris
You are likely to receive better help and a quicker response if you post
your questions to the mailing list. I'm running hard at the moment, so
your mail has sat in my inbox for a few days. I've only had a very quick
look at the images you sent me and these are my first thoughts:
1. The resolution of your sample map (the example of what you are trying
to achieve) is VERY much higher than the resolution of your data
2. The maps you have created appear to have large areas with the same
data values. Either there are problems with your source data or you have
lost precision when creating the map. Did you import float values into
an integer map?
3. To produce a higher resolution map you may need to use a model like
r.sun from GRASS and calibrate it against your data (if you are sure
your data is right!)
Regards
Craig
