How did I miss that I could create polygons with the fishnet. Thank you very much, exactly what I needed!

That would work perfectly, just one little hiccup I only have an ArcGIS Standard license with Spatial Analyst.

Had to do a few different version of this, but got it to work, thanks! I've added an extra credits question to Jayantas comment, feel free to weigh in, if you know the answer

Thank you, both of the suggestion works. Much appreciated. Another question a bit different, can you convert a raster too vector, without it grouping raster cells, so that basically each raster cell becomes a polygon? Input raster Unwanted output vector Wanted output in vector No data 1 No data No data 1 No data No data 1 No data 3 1 8 3 8 3 1 8 2 2 4 2 4 2 2 4

Hello I'm have two polygon layers, one have been dissolved, the other is the original data with a lot of smaller polygons in it. The polygon layers overlap each other. Each of the dissolved polygons have an unique id, that I would like to add to all the smaller polygons, so I can see where the smaller polygons belong. I'm thinking some kind of join or similar based on the spatial relationship (overlap), but I can't get it too work. Tried adding a concept illustration: Input: Wanted output Dissolved polygon ID Size Small polygon size Small polygon ID 4479 10 1 4479 1 4479 1 4479 1 4479 1 4479 1 4479 1 4479 1 4479 1 4479 1 4479

Alright, I've tried what you suggested with the below output. I'm not quite sure (even though I've read the How it works) what I'm looking at to be honest. (Might be I'm just a bit slow). Input was Int_RasterCa3, which is the depth in each cell Unit: Centimeter. The output RegionG_Int_1 has a whole different spectrum, also when I use Identify it doesn't look like adjacent cells are grouped? Greatly appreciated the help Dan

Thank you for the quick reply. I get an error 000864,Input raster: The input is not within the defined domain. ERROR 000863: Invalid GP data type. The raster is a GeoTiff with float values I think, is that an issue? Edit: I can see it must be an integer type. So I should try to multiply my values with 10000000 (or there about), convert to Int (using Int toolbox) and then try again?

Hello I've got a raster that represents the water depth at a specific return period for a whole municipality (e.g. a lot of cells both with neighbours and single cells). The grid is a 10x10 m, so I know I can calculate the volume of each cell as depth x 10 x 10. What I then need is to group these together, so that I get the sum of all connected cells, preferably I then need to convert that to a vector/area/polygon with the total volume. So basically all individual raster cells that touch each other need to be summed up and grouped together. I've got 3d analyst and spatial analyst license along with Standard Arc license. Any help would be much appreciated.
