I'm trying to get a fast workflow established for merging rasters.
In this example, we have 151 ASCII text grid files. I take a list of those file names, jam them into my Google Sheet
, and then run the calculated field contents in a Release 9 command window.
From this point, I have to open the map component in order to access the "Edit -> Merge -> Merge Images..." dialog. The map takes about 5 minutes to open. The info messages on each layer is just that intermediate levels are not updated, which I don't care about in this workflow.
I click merge and a new image component is instantly created, apparently of the correct dimensions but containing no data rows.
So first, am I doing something wrong?
Second, the magic that happens when the MERGE button is clicked would be wonderful to see in its SQL form, which would remove the need to interactively "open" (and await) the map component rendering on-screen, and facilitate a SQL-only interface for this workflow. Is that possible, to see the commands that are run for "Merge Images"?
