Dear all,
I am trying to replicate some results from a publication. There, one of the datasets they use is WISE30sec map (available for download here: https://www.isric.org/explore/wise-databases). My problem is that even tough they state the following:
"The zip file includes a raster GIS file (WISE30sec) as well as a range of soil attribute data files (see Appendix 3 of the documentation). Using ArcGIS® or similar, users may join the raster data to the derived soil properties files, as managed the MSAccess® database (WISE30sec.mdb). Linkage is through the map unit code or grid cell identifier (NEWSUID) of the raster set and the NEWSUID of the various soil attribute data files."
I am unable to perform the above-mentioned join as I fail to find the grid cell identifier (NEWSUID) when using the Add Join function. ArcMap only shows the fields "ObjectID", "Value" and "Count" and none of them coincides with values shown at the tables I am trying to access. I have tried to copy raster and build attribute table but it didn't work. Also, when I put it in R, I cannot see these attributes that the raster is supposed to have.
Thank you in advance.
I suspect that the authors may have converted the raster to a polygon feature class, which was then assigned the NEWSUID field. At that point, they could do a join to the attribute table. But, they are possibly missing a few steps because how would you correctly assign the NEWSUID values to the new polygons. Otherwise you would not be able to link the correct attribute field back to the correct polygon field. Something does not seem right.
Do, carfully, conversion from raster to vector, then join tables.
Dear Abel Ruiz-Giralt ,
I tried to do the join with the dataset WISE30sec and some tables in the mdb DB. It worked for me, both joining the table directly form the TOC and using the Add Join tool, as you can see in the attached pictures. I used ArcMap 10.3.1. Is there something i missed?
