Aggregate raster to another layer

KevinWesselink — Tue, 19 Dec 2017 10:02:23 GMT

Hi all,

I have created a raster dataset which I want to aggregrate to another layer I have. This layer has borders of neighbourhoods and I want to map the average of each neighboorheid in my raster.

My raster looks like this;

And I want my output to look like this;

Do you guys have some tips for me?

I am fairly new when it comes to arcmap so any tips are welcome!

Cheers,

Kevin

I you have access to Spatial Analyst, the first thing that come into mind would be using Zonal Statistics—Help | ArcGIS Desktop . What do the colors in your map represent? I see blue, 2 tones of orange and red. Are these somehow numeric values? In that case Zonal Statistics would be the tool to use. In case that is categorical data like land use or something similar, you should use Tabulate Area—Help | ArcGIS Desktop in order to get information about each land use in each neighborhood.

Hi Xander,

Thank you for your answer.

The colors represent a combination I created in a weighted overview of landuse (vegetation and roads) and groundwater. I will test out both tools and check the results.
