create contour lines on raster based on value

MeghanKulkarni1 — Wed, 12 Jul 2017 22:13:07 GMT

Hello,

I have sort of weird problem. I have raster data set having 3 unique values. I want to create contour lines around this raster based on value at particular cell.

Here is screenshot of my raster data set.

Can someone help me with this?

Thanking You.

Hello Dan,

Thanks for your reply .

how it works is how I want my contour in output. What interval should I use?

Tried with 10, 15 didn't worked(blank poly lines generated).

To elaborate further, my whole raster data set contains 2, 3 or 4 pixel value. I want contour line generated around these values which have same value.

Thanking You.

My Best

you can only use contour values that are within the range of the cell values you have. My guess is that your map only has values of 1, 2 and 3 so your interval won't work.. unless you can provide details to the contrary
