If needed we could just add to the current code and move it into the mosaic dataset from the GDB. Any...any...help would be massively appreciated as we are all at our programming limits.

Re: I'm trying to convert TIF images into a Mosaic dataset using Python. Somebody here has created the Python working right now to a raster GDB but they can't get any further. This is my one area of weakness (programming/coding). Does anybody know how

JohnPavek — Wed, 26 Feb 2020 21:27:58 GMT

Our main goal though is to go from the TIFFS straight to the Mosaic dataset if possible

DavidPike — Wed, 26 Feb 2020 22:00:52 GMT

Does it have to be from python? Creation of a mosaic dataset and importing rasters is an easy process and you can just provide a workspace. I'm sure it can be done in arcpy if needs be though.

JohnPavek — Thu, 27 Feb 2020 16:24:20 GMT

Thanks for your reply David!

The way the process works ibased on the code I provided is this...the TIFFs are modified Then thru a process that runs in Task Scheduler every morning at 7 AM any changed TIFFs are found and added to the raster GDB raster dataset overwriting what is there. Then the GDB and its associated TIFFs are served out to a webservice. So we have to automate the process. But like I said we could just keep the process as is but add a step to take the raster GDB into a mosaic.

To this community: we are really stuck here and searching for help anywhere we can find it. But I figured that this community would have the best experience and ability to help. Please...please...if you can offer something let me know. I'm going to look into Modelbuilder and see if it can help. But I'm really a blind person now swinging in the dark with 1 hand tied behind my back.

Re: Need major, major help converting Tifs into a Mosaic with Python

DavidPike — Fri, 28 Feb 2020 15:28:04 GMT

Can you explain the steps of the code and what its doing/think it's doing. Does that code block work? I can see raster catalogues mentioned in the code. Full explanations of what the data is, looks like and what you want to achieve will help people to help you.

Re: Need major, major help converting Tifs into a Mosaic with Python

JohnPavek — Fri, 28 Feb 2020 19:18:31 GMT

Hi David.

Ok...I'm a;ways trying to find the right balance of info in GeoNet vs. too much...

The workflow is this...people make changes in the TIFFs using CAD. Each morning at 7 AM a job in Task Scheduler kicks off the code. This code will go and find ones that have been changed and replace them into the raster dataset. An earlier version just recopied all the TIFFs each time but I think this version just dealt with the changed ones. Then this raster dataset is used in a few mapservices. This code works fine and I have learned that if it works let it be as much as possible as I have found not my type of thing.

Now there is a request to go to the Mosaic dataset instead of the raster dataset. I figured since the raster dataset is there and working why not take the raster dataset and just change that to a Mosaic dataset. That way I just add a new codeblock and work that in instead of rewriting the whole code. I've included a few images of the raster dataset below.

Re: Need major, major help converting Tifs into a Mosaic with Python

DavidPike — Fri, 28 Feb 2020 19:35:18 GMT

We need to get terminology right.

.tif is a tiff file outside a geodatabase.

A raster dataset is a raster inside a geodatabase in FGDBR format.

A Raster catalog is either unmanaged or managed (references raster file paths or contains the rasters respectively) and sits inside a geodatabase. This is also very outdated.

A mosaic dataset sits inside a geodatabase and references rasters and is the recommended container.

Re: Need major, major help converting Tifs into a Mosaic with Python

JohnPavek — Fri, 28 Feb 2020 20:13:09 GMT

Ok...I think it is a raster catalog if I remember my ArcCatalog symbols right. Plus I tried something and an error i got mentioned that it is "not unmanaged" which I would assume means managed (yes...that is what the message said). If you look at the images shown on the last message it includes the images themselves. I definitely need to get it to a mosaic dataset. The person that created things left a long time ago and the documentation is very weak. So putting together what I can. I'll try to find out more. Is there something I can do that would definitely show what it is?

Re: Need major, major help converting Tifs into a Mosaic with Python

DavidPike — Fri, 28 Feb 2020 20:40:21 GMT

If you right click, properties, fields tab then at the bottom it may have a managed yes/no box.

It looks like line 239 is deleting your old tiff and 243 is inserting the new one.

I would copy all your tiffs into a new mosaic dataset, then set line 243 to copy new tiffs into the mosaic dataset. If this works be aware that line 239 will have to change to remove old tiffs from the mosaic dataset, or simply set 243 up to replace existing.

I'd get someone to rewrite that whole script also.

JohnPavek — Fri, 28 Feb 2020 21:03:55 GMT

Hi David

Here is what I saw and I now know it is a Raster Catalog because the heading of the Properties: box is "Raster Catalog Properties" which I don't why I missed that. This is one of the reasons I hate coding/programming...you miss a comma and your lost for hours/days/weeks...I don't have the patience for that.

I will look into your suggestion David about the code. I'm going to try to use Modelbuilder to help me get the code together. It might be worth doing your suggestion but I have learned if it is working don't break it. If I just could get the Raster Catalog GDB to convert/be loaded/etc into the mosaic dataset then I could use Modelbuilder to get that to work, export out to Python and add the codeset in getting that to play nice with the other code.

Re: Need major, major help converting Tifs into a Mosaic with Python

DavidPike — Fri, 28 Feb 2020 21:33:16 GMT

Use Create Referenced Mosaic Dataset. If the files which get removed and replaced in the raster catalog keep the same names, you will only need to create this mosaic dataset once, then it will simply reference the paths in the catalog. Ie create it once and that's it.
