Reclassify Slope - How does ArcGIS handle break values?

BenjaminVang-Johnson — Fri, 18 May 2012 14:05:26 GMT

Hello. I am reclassifying a slope raster into categories such as 0-1, 1-5, 5-10, etc. I assign my break values as 1, 5, 10. During reclassification how does the tool handle cells with the exact value of the break value? For example, if a cell has a value of exactly 1 does that cell get reclassfied into the 0-1 group or the 1-5 group?

Thank you

The break value will be reclassed with the first group. For example your value of 1 will go into the 0-1 group.

I tested this with a random raster with values from 1-10. I reclassed it to 3 values: 1-4: 1; 4-7: 2; 7-10: 3. The value of 1 returned 1 (1-4), and the value of 7 return 2 (4-7).
