Hey again!
It’s has been a while since my last post, but I have to say that this is because I have been keeping myself busy with articles, conferences and so on so I have an excuse 🙂
Anyway, today I encountered another of those little problems that sometimes can make your life difficult.
If you open a raster in Arcgis and you dont want the default display, you can always get the layer properties and change the color ramp and so on. However, if you want to classify your values you have to choose: “Classified” or “Unique values” (depending on what you want). The problem comes when you have “to many” unique values in your raster so Arcgis does not allow you to change it.
Well, there is a simple solution to this, you just have to:
Go to tools/options
Go to Raster Tab
Click the Raster Attribute Table sub-tab
and finally increase the maximum number
This will allow you to compute all unique values you need to do a Manual classification or any other type you want. However, I have to say that if you have an old computer and thousands of unique values this will take a while…
I hope this is of some help 🙂
I’ll probably see you soon as I’m preparing myself for a hardcore modelling time in the next few months!
