The authors of the land cover data have already added pixel values for the different vegetation types. The susceptibility model that I am following has different coefficients for each type of vegetation. I am not sure how to specifically calculate for each vegetation type because there all within the Land Cover raster. I also have lithology data that I will be using as a proxy for rock strength and was wondering how I would go about adding that value to each pixel for its respective category.&nbsp;</P><P></P><P>Any advice would be much appreciated.&nbsp;&nbsp;</P></BODY></HTML> Thu, 14 Nov 2019 21:17:01 GMT https://community.esri.com/t5/911-gis-questions/nominal-data-raster-calculation/m-p/785520#M212 ToniRamirez 2019-11-14T21:17:01Z Re: Nominal data - raster calculation https://community.esri.com/t5/911-gis-questions/nominal-data-raster-calculation/m-p/785521#M213 <HTML><HEAD></HEAD><BODY><P>Hi&nbsp;<A href="https://community.esri.com/migrated-users/369267">Toni Ramirez </A></P><P>It would be advisable to perform the calculations separately for each type of vegetation</P><P>If you also have lithological data, it is recommended that you also separate them.</P><P>Finally to get a final raster you can do raster sum</P><P>Everything will depend on your goals.</P><P></P><P>I hope it helps</P></BODY></HTML> Tue, 26 Nov 2019 21:02:32 GMT https://community.esri.com/t5/911-gis-questions/nominal-data-raster-calculation/m-p/785521#M213 JuanSantos 2019-11-26T21:02:32Z
