Extract data from raster map by polygon

[Mikhail]

Hi, my map has two layers. One is a vector map that contains borders of a number of geographic units, and the other is a raster map of soil types. I'd like to 'match' them, and the ideal outcome is that the attribute table for the first layer would have an additional column 'Soil type', that would have the data from the corresponding area of the raster map. Is there any way to do this?

did you start with the extraction options? for example

Do you want areas?

Thank you. Extract by mask looks promising, but I do not need a raster map as an output. Essentially, my raster layer is a colour-coded soil map. What I want in the end is an extra column in the attribute table for the second layer, that would show the colour per each polygon. In those cases where the polygon contains areas with different colours, I'd like to get the colour that covers larger area. I can do this manually, but it's time consuming. I wonder if there is a way to automate this work.

using only value and count as the statistics options then join the table to the featureclass

make sure you read this as well to see the procedural concepts

Thank you, this should work. The only problem is that I imported my raster map as a Web Map, and the tool  does not recognise it as a raster dataset. Do I need to convert it to a dataset?

make it a raster, preferably a *.tif stored in a folder .... which is the preferred raster format

do the web stuff after data preparation and/or analysis is complete
