Region Growing Tool

Dear all,

Does anybody make a tool similer to "Region Growing Properties" of ERDAS IMAGINE?
Any suggestion will also be appreciated.

There is a tool in Spatial analyst that will do this . It is called 'Expand'. It can be found under ArcToolbox > Spatial analyst tools > Generalization > Expand.

Thanks Jamie.

"Expand" tool looks like working well when applying Thematic raster data,
however, what I would like to have is expand an area on Multispectral
continuous raster data, satellite imagery, based on Euclid distance
for four neighbor or eight neighbor direction.
This function should be quite useful to generate boundary polygon of
distinctive area of multispectral data like water, single species forest,
and so on.
In fact, this function is contained on ERDAS Image Analysis for ArcGIS,
but I would like to populate it on "ESRI" ArcGIS due to the political,
competitive, reason.

Best regards.

That would be useful. I would submit that to the ideas site. It's something that ESRI might want to take into consideration for the future as they move into the more into world of image processing.

Thanks Jamie.

I look forward to seeing something good on near future ArcGIS.
In fact, hand digitizing water boundary is quite unproductive procedure...

I think it's a good time to rehash this request.

Raster function of ArcGIS Pro is good, however, loading this "Region Growing"

will strengthen it more.

Us cases:

- Flood analysis

- Getting homogeneous training samples for future product concerning AI like deep learning as well as Image Classification

Makoto, I suggest posting this as an ArcGIS Idea. (Click ArcGIS Ideas at the top of the GeoNet page.)
