Here it is.....let me know if you have any questions. I'll be working on the TIFF to GRID conversion. [ATTACH=CONFIG]26160[/ATTACH]

I realize the image is unclear.....let me try again.

Thanks Shitij. Take a look. Hope you can see this okay..... [ATTACH=CONFIG]26159[/ATTACH] The selection is based on a shapefile which has about 15 polygons, which should be zonally linked to the rasters via the Zonal Statistics as Table tool......right?!!?! So the output is incorrect in that it just doesn't match what the corresponding raster files have as stored values, which is what I was expecting. I understand that the statistic is performed as an average of the pixels within each polygon, but the output for some of the rows is assigned a value even when I know for a fact there is no value i.e. the output should be zero!!! I hope this isn't too confusing. Let me know what you think. Thanks.

Esri analyze tool only works well under the projected GRID data format (ESRI raste format). So convert it to grid format first. How do I go from TIFF to GRID?

Hi Shiko, How are you selecting the polygons? Are you sure the selection is being passed to the next tool? How is your output incorrect? Are the values wrong or all records Null? Always consider attaching a snapshot of the model with the forum post. It makes it easier to see the upstream and downstream processes. Shitij I've actaully been struggling with that, which is why I haven't. Maybe you could walk me through the process. What I was trying to do is copy the model by doing a PrintScreen and then converting the image to a JPEG or other image file but to no success. How do you usually do it?

I dont know if the tiff input is a problem? I usually use grids. Also, what about cell size? What is the cell size of the tiff, then have you set the environment up for your analysis? Well, the cells are pretty tight.....60 by 60. What environment settings in particular should I adjust? Right now I only have the Workspace environment setting checked...I'm not quite sure about the rest.

So I have a model that utilizes the Zonal Statistics as a Table tool and it runs beautifully. However, the output is incredibly false. The input feature zone data is a shapefile comprised of a select few polygons. The zone field selected is FID. The input value raster is a .tiff file which stores the correct values for the output. The output table is saved to the workspace chosen by user. And the statistic performed is the MEAN. Which means the output for every FID row is an average of all pixel values in the raster file within that polygon shape. What's happening when the model runs is that the output is just incorrect....almost like there is no zonal recognition happening. Is anyone familiar with this and perhaps what I can do to make the output correct?? Thanks

Thanks Chris....and Jim....You both had the same idea, which I will try right away. Cheers to you both 🙂

Hi folks... I have a working model which runs perfectly on my computer but when the model is open by someone else on their computer, we encounter workspace issues with the output. The model currently incorporates the Zonal Statistics as a Table tool, where the output is saved to my hard drive. How can I change the settings so that the model will automatically know what drive to save output in regardless of the user computer. See output path below: C:\Work\Selection_Results In other words, is there a way to ensure that output will go into the folder Selection_Results no matter where the entire folder is saved i.e. USB Drive, External Hard Drive etc??? I hope this isn't too confusing, I just simply want model builder to know where to read input from and save output to, without having to reset the paths in edit mode on another computer. Note: "Store relative path names (instead of absolute)" is checked in the model properties.

Alright.....I figured it out y'all. 😄 See Below: This is directly from the Help Menu on Model Builder. Super helpful. Note:Add To Display has no effect outside ModelBuilder. When running a model tool from its dialog box or the Python window, the Add To Display setting will not be honored. To add model data variables to the display when running the model from its dialog box or the Python window, make the data variable a model parameter, then enable the Add results of geoprocessing operations to the display option from the Standard toolbar: Geoprocessing > Geoprocessing Options > Add results of geoprocessing operations to the display. Copyright © 1995-2012 Esri. All rights reserved. One other problem I ran into was the fact that my output happens to be a table and the name of the location where I was saving this output included spaces.....which is not supported for any type of Table or Coverage Output. Just an FYI!!! Cheers

Hello folks, I'm hoping one of you have a solution to my problem today. I have a model that runs perfectly in the edit mode, and does exactly what it should by displaying the results that have the setting "Add to Display". However, when in comes to running the model outside of the edit mode.....it'll run, but won't display the results on the map. Since the model works okay in edit mode....I'm sure it's fine. I just need to figure out what setting to change so that it will work from the toolbar as any other model should. Please help....I need to fix this like yesterday. :confused: Thanks

Does anyone in the community have a link to a good video that demonstrates working with feature sets and creating models on model builder that allow the user to select polygons or other features of interest as input within the models ??? Much appreciated 🙂

Hi all, Have any of you ever experienced having less rows of data after running the zonal statistics tool on model builder? I wonder if it has something to do with the fact that data could be missing in the raster files for the corresponding polygon in the shapefile?! Any thoughts, comments, suggestions are welcome. Thanks

So I'm up to the Script Tool point with the model.....I switched it up a little but I don't think that should cause the error message below: Expression x(%Selection%, %Workspace%) Code def x(Selection,Workspace): arcpy.env.workspace = Workspace if all in [arcpy.Exists(s) for s in Selection]: return True else: return False Data Type Boolean After running: ERROR 000539: SyntaxError: unexpected character after line continuation character (<expression>, line 1) Failed to execute (Selection_Exist_Check). Failed at Tue Jul 16 13:51:52 Note: This was happening even prior to your model suggestion, which works well up until this point. Also, Workspace is the shapefile of interest. Thanks

Excellent!!! I know what I'll be working on this afternoon 😄 Great help.Thanks for your time.
