Raster to Geodatabase Issue

JosephinaReyman — Tue, 03 Dec 2024 19:28:25 GMT

Hi I am trying to use the "Raster to Geodatabase" tool, however, whenever I hit run I get this error.

"Failed to convert Topos Wetlands Symbols\SLC_Topos_Symbols_Extracted_Wetlands_Subsamples. can only join an iterable"

The raster doesn't even pop up in the geodatabase.

Does anyone have an idea how to fix this?

Hello
What I understand is that you want to put a raster into the Geodatabase?
Am I correct?

Yes I have over 40 rasters. I was hoping I can use the tool to put them in all at once, but it doesn't seem to be cooperating.

Use the ADD RASTERS TO MOSAIC DATASET tool, so you can enter them all at once.
But first you must create a CSV file so that it can recognize it.
Here I attach an image of the structure of the table that you must make and that you must be able to see inside it.
In Camera ID, you put it the same as the image, in raster you must put the address of where your images or rasters are located, the SRS is the coordinate system, you must enter the one that corresponds to you.
I hope it helps you, and if you don't understand something, let me know. Greetings.

Thanks I'll give it a go.

Rather than storing the rasters in your geodatabase, you could create a mosaic dataset in your geodatabase and then reference the original source rasters. The workflow to do this is here.

In the future, or for anybody else looking, try simply removing the raster from the group before fiddling with a mosaic dataset. The characters "-" and "/" mess with the iterable or whatever, and the group adds one to the item name artificially, as seen: "Topos Wetlands Symbols\SLC_Topos..." I had this error, and ungrouping the rasters immediately fixed the issue.

Hi, checking in from the future to say that this solution worked like a charm. Thank you!

I have run into this same error and I do not want to mosaic my rasters. I am not following what JoshBerna means by 'removing the raster from the group'. It appears that you were successful in following his guidance. Can you help me understand the processing steps? TY!

If your raster is grouped/in a group with other rasters/items in the contents pane, ungroup it, then try to add the raster to the geodatabase.
