I’m getting an error “The following 134 raster value do not have corresponding entries in the value map.” I followed the same steps mentioned in other threads, but still the issue is the same. Carbon Pool Table: [carbon\_pools\_USI.csv](https://community.naturalcapitalalliance.org/uploads/short-url/3KMDCOHBCe0ari8UQ7mdpkLTs99.csv) (772 Bytes) Raster file: [Map.tif](https://community.naturalcapitalalliance.org/uploads/short-url/ftoznnPDRC9v4QQUmXNZ3cZg6NK.tif) (1.5 MB) Could you please help me? ---

Hi @Nasna - Thanks for including your data. Looking at your Map.tif raster, it appears that it has 3 bands which are RGB (red/green/blue) values. The model will use the first band, so it is reading the R (red) values, which are not the land use codes represented by the carbon pool table. So you’ll need to look at your source data and figure out how to make a land use map whose values represent the land use codes, not RGB values. ~ Stacie ---

Thankyou so much, it worked! ---

Hi Stacie, Apologies for asking the same question which was posted on other threads. I went through similar threads but was not able to clear my doubt. html output I obtained is 25446.42 Mg of C. How can I interpret this result? Is this Mg of C for entire project study area? or Mg of C / tonnes? or Mg of C / m2? ---

Hi @Nasna - Yes, the values in the Aggregate Results section of the HTML report are totals for the entire project study area. I’m noticing now that the User Guide is missing a description of these values, I’ll add that information. ~ Stacie ---

Appreciate your prompt response. Yes, the user guide doesn’t specify the description of these outcomes. Is there a way to correlate HTML result and raster results? Are they related in anyways? ---

The HTML values are the result of using a method like Zonal Statistics to sum the per-pixel carbon values given in the output rasters _tot\_c\_cur.tif_ etc. So yes, the HTML results are directly based on the raster results. ~ Stacie ---
