How can I create raster from the value joined from a table in gSSURGO product

[TianyiZhang]

Hi,

I am a new to ArcGIS. I am using a soil GIS product (gSSURGO). The UserGuide can be seen here (https://docs.google.com/file/d/0B61_...it?usp=sharing).

In this production, they have a raster file (the MuRaster_WV in Page 8 of userGuid), which have a ID key (mukey in Page 10) that is used for linking to other variables stored in tables. As you can see from userguid, they first load MuRaster_WV (P.8) and then link it with other three variables in muaggatt (P.17), and then show the spatial distribution for hydgrpdcd (P.20) and aws0150wta (P. 23).

So far so good, but I want to resample and merge aws0150wta data. But I found I failed probably because the aws0150wta is still in table but not as a raster file (is it right reason?). Thus I am wondering how can I create raster from the value joined from a table in the production?

An example data can be downloaded from here (https://docs.google.com/file/d/0B61_...it?usp=sharing).

Sorry my mother language is not English. If you cannot understand, please let me know. I appreciate to your help. Thank you very much.

Hi Tianyi,

I wasn't able to open any link in your thread. but if the data is in the VAT (Value Attribute Table) of the raster use the tool "Lookup (Spatial Analyst)".

In case the data is in a separate table you can use the tool "Reclass by Table (Spatial Analyst)". From the Help:

To reclassify individual values, use a simple remap table of two items. The first item identifies the value to reclassify, and the other item identifies the value to assign to it. Set the 'to value field' the same as the 'from value field'. The value to assign to the output is 'output value field'.

Kind regards,
