While sharing screens, we went section by section in the zonal stats tool environments confirming it was set to the same thing. Is there anywhere else we should check for differences? - Thanks

‎07-12-2016

I recently shared a GIS tool with another user; however we are not getting the same results. We made sure to test the tool using 1) Identical inputs and 2) the same version of GIS. But we keep getting different results when running the tool on different computers/servers/systems (we work at different companies). We have gone step by step, comparing results as we go. We narrowed it down to a problem when we perform "Zonal Statistics". The inputs are identical (running from a gdb) but we do not get an identical output raster. Could there be options or default settings we have different that could be causing the discrepancy? If so, what settings should we look at specifically? Thanks

I'm using the Iso Cluster Unsupervised Classifcation to take a CIR aerial and find the impervious cover. I'll tell it to use 6 classes but on occasion my output will only have 4 or 5 classes. This is a step within a larger model so my solution needs to be general and apply for any input raster. Thanks

Ok - I found a solution (posting in case someone reads this later with a similar problem) 1) Model parameter = Results Folder (not a gdb like I had it set up to do) 2) First Step in the model - create "Temp" GDB in the user defined Results Folder 3) In the raster to polygon tool, have the output feature polygon be %Results_Folder%\Temp.gdb\%val%_poly The tool requires the output path to have .gdb or it will append .shp to the name. This accomplishes that without having to manually change the path. Thanks everyone for the help!

%val% is already a parsed path variable. The tool itself will append .shp to the file name if it doesn't read .gdb in the file path. This happens when I set up the tool in the model and have only been able to change it manually as a parameter later when I try an run it.

I am using a file geodatabase. The problem is that when I tell the "raster to polygon" tool to create the output polygon features as %temp%\%val%_poly it will append .shp to the file name. However, %temp% is a geodatabase and doesn't allow .shp I've been getting around this by setting the output as a parameter and telling it to create the feature as E:\temp.gdb\%val%_poly each time I run the model. My final version can't ask the user to include an inline variable.

The files are too big and it kept crashing in memory. Using a defined gdb stopped the crashing but then it wouldn't let me use the location as an inline variable.

I created a model to iterate through and process rasters and convert the desired value field to a polygon. The final model needs to be robust and very user friendly. However, when I try to use an inline variable to put the polygon into a user defined temp geodatabase the tool will add ".shp" to the output file name. Unless it is pathed to a gdb in the model it will add the ".shp" But since the output is really a gdb, it causes an error during the run. The problem: I've been getting around this by making the polygon output into a parameter and changing the location myself each run. But then it's not exactly user friendly. How I "fix" the problem: How can I prevent the automatic addition of ".shp" on this step? And leave out my work-around solution so the eventual user only defines a temp gdb? (None of the other steps have this issue with the inline variable) Thanks

Thanks! My final product needs to be user friendly and the batch won't work for that. But I will definitely use it when I'm processing on my own from now on.

Thanks! There was no particular reason I went with a shapefile versus a feature class. I just learned about the size allowances today from a coworker and I think that will help fix a lot of the problems. How do you set up a batch run with GIS? I've only done it before with just a shell script. My "final" model is needs to be something anyone can run through the tool interface in GIS.

The desired format is a model so that it can be easily used by others or modified later. I like the idea of integrating a script into the model. I'm just not as familiar with doing it that way (I either write the whole script myself or make a model, I'm still learning how to do them together) Do either or you have example scripts of your suggestions? Is there a way to wait until there's an error and tell the model to just move on to the next? Or do I have to predict what all the errors might be an write something to catch them all? Basically my task is 2 fold 1) process 300 rasters and 2) have a robust model that can be rerun later without any errors

I wrote a model to process a large number of rasters. It asks for an input folder and it will iterate through each raster to perform the steps. Some of the raster outputs are very large, and I will occasionally get an error and stop the whole model. Attached is screen shot of my model. It will only fail at: (1) the "raster to polygon" step for shapefile exceeding 2GB limit or (2) the "dissolve" step for lack of memory. (Note: none of the data is 'intermediate' because of the memory issues, the dissolve polygon can just be extremely large with over 3 million features) What I am looking for A WAY TO KEEP THE MODEL RUNNING. If a step fails, is there a way that I can keep the iteration going and move on to the next raster? It takes ~3hours to process each raster and I need to be able to run this overnight and on the weekends. If it fails on the first raster, I'm loosing too much of my processing time so I want it to at least keep running. Thanks PS: If you have ideas on eliminating the failures altogether, that would be helpful too! I have almost 300 of these to do.

Thanks! I'm fairly certain now that they sent us the wrong aerials. I just needed to be sure before going back to them.

I have a .sid raster that apparently has infrared. But it only has 3 bands, making it most likely RGI or something similar. My metadata does not specifically tell me which band corresponds to which wavelengths. When I load it into GIS it defaults to R=band1, G=band2, and B=band3. Is it safe to assume band 3 is infrared? Is there a way to know for sure? I have no other supporting documentation to help me, just the raster. -- Thanks Note: there is a slight possibility that the image does not actually have infrared. When I look at the lake, it is almost black like other false color images suggesting it probably does have infrared. I just need be able to know without a doubt if I have infrared or not.

To was polygon to polygon for the intersect. I wonder if there was some lock on the data? I eventually wrote a model that iterated select each boundary to perform intersect and generated over 300 individual shapefiles clipped along the boundaries. Then merged all of them altogether after it ran. (Longer method, but it worked) Thank you so much for the help!
