The feature is used to extract by mask (boundary cut-out) but all the other datasets are rasters. Nevertheless, I understand the point made. I have a storage constraint that is why I was avoiding inline model variable substitution but it looks like its the way to go and then merge the raster. I had looked at the help doc for Append so many times and I did not understand that the point "This tool does not perform edge matching; there will be no adjustment to the geometry of features" means it does not honor Snap Raster environment setting. Is that right?

I am having a problem with the output of an Append tool because the result is off 500m by 18m from the raster dataset in the snap raster environment of the modelbuilder. Software: ArcGIS Desktop 10.6 Background: The Append tool is the last tool in the model. The model has an iterate feature selection which chooses features by name, performs calculations through an RC and then is supposed to append the result in an empty raster. Problem: The result before and after the append is correct i.e. its data in the cell is correct on both accounts but the appended results shifts 500m to the right and 18m up. All snap and processing extent properties have been re-checked and are set correctly i.e in the modelbuilder and in the making of the empty append raster dataset. Possible solutions done: many! Including running the model in the ArcCatalog, running it in the foreground in ArcMap, changing the Schema type in the Append tool, setting up the environment settings again in the Append tool (over and above the ones for the modelbuilder), reducing the results by 1000 (the result has many zeros), running iterator in a sub-model and the Append tool in a master model….but nothing seems to work. This last solution gave an error that one of the datasets during the beginning of the iteration can not be deleted. My last option left is to shift the whole appended dataset with the Shift tool. Before I do this, I wanted to share and ask if there's anything am missing and what I can do to have the appended results snap to raster correctly (without the shift).

These questions and many others helped me realize the intricacies in any spatial analysis project thus I started at the very beginning. Thanks at Xander Bakker. PS:Sorry my reply is too old.

Hi guys, I looked at the problem again and used other tools in modelbuilder such as GET FIELD VALUE and CALCULATE VALUE to get the results I needed.

Hi all, I have a model where I would like to perform further geoprocessing, if it fits a certain condition. To be more specific, I have dataset which i put through the CON tool and the output is either 0, 1. Thereafter, I perform ZONAL STATISTICS whose output, I DIVIDE out from the original dataset. When the output of the divide tool, if it is greater than 90% to go back to the output of the CON tool and "reclassify"* the 0 to 1 such that I only have 1 in the whole dataset. If the output of the divide tool is less than 90%, no further processing is needed. I have attached a screenshot of the model. I checked the website Branching: Implementing if-then-else logic for IF/ELSE statement as a starting point but I have no skills in python and thus need help in making the script. The other website checked Using If-Then-Else logic for branching—Help | ArcGIS Desktop, the examples open out to the ArcGIS blog and have no further helpful information that I have found. I am using ArcGIS 10.6 and have Spatial Analyst extension. PS: "reclassify"- am not sure if this is the right tool to use but i used it for better explanation.
