I try to understand the color ramp in TIN and IDW interpolation. I work with height points layer. The low value in 8 and the highest value is 584. With the interpolation plugin i create TIN raster with Cellsize xy 5.
I get this raster:
and this is the color ramp:
This in the same point but with IDW interpolation:
in the TIN interpolation, i get this value:
and in the IDW interpolation, i get this value:
I don't understand:
- Why there are differences in the color ramp between the two options?
- What represent the value of some random point (not my layer points) when i use Identify Feature?
- Why the color ramp don't include the minimum\maximum height point value?
