Suitability map with interpolation from value... to value...

Discussion created by annekull on Aug 13, 2012

I need to make a suitablility map which has to consist of following classes:
1. values from 0 to 1,5 must have value 0. It is easy, but now comes the tricky part:
2. values from 1,5 to 2 must change gradually from 0 (for value 1.5) to 100 (for value 2).
3. And then again from 2-25 the new value would be 100 and
4. from 25-40 the value must again change smoothly from 100 (for value 25) to 1 (for value 40) and
5. all values from 40 and up must have suitability value 1.

What is the best solution for creating this kind of map?

Best regards,
