Hello and thanks for looking at my question. I am taking historical aerials and creating a map layer.  The aerials are 100 foot, 200 foot and 400 foot scale.  As none of the scales cover the total area I am working on I have created a Raster dataset for each scale of the aerials.  There is over lap at the edges and there are 100 foot scale aerials that may lay on top of a 400 foot scale if there is more detail in just a portion of the 400 foot scale aerial. So I have 3 raster datasets, one for each scale, now I want to mosaic them all together to have full coverage of the area I am working on.  That is easily done, but...  the 400 layer is always the top raster layer so it covers the more detailed layers if there is overlap. I have tried adding the rasters in different orders and I have tried setting the properties on the mosaic dataset for either ascending or descending, and/or setting the default mosaic operator to first or last to set the overlap based on the input order of the source data when adding rasters.  I still get the same result. So, any ideas on what may not be set right on the mosaic dataset, or how I am constructing the rasters that could cause this. Dale, .  ... View more

Continuing on in learning Python as I go I am at the next issue.  I have created a Python toolbar add-in with a button for use in ArcMap. Start up ArcMap, toolbar is there, select button and a menu I created in Python is displayed.  It contains radiobuttons and comboboxes. On the reset button I want to clear the radiobuttons, clear the selected item from the combobox so it is not selected-blue, and set the combobox back to the first item in the list. When I run the script from PyScripter the menu appears and I can clear and reset everything so the menu looks like it just loaded. When I start ArcMap the Python toolbar appears, select the button, menu appears, select a radiobutton, select an item from a combobox, that all works. When I select the reset button I get the following error whether it is a radiobutton or a combobox: I have the python window open in ArcMap so I can see what is happening. Exception in Tkinter callback Traceback (most recent call last): File "C:\Python27\ArcGIS10.5\Lib\lib-tk\Tkinter.py", line 1542, in __call__ return self.func(*args) File "D:\Applications\Python\Layers.py", line 63, in reset RB1.selection_clear = var.set(0) NameError: global name 'RB1' is not defined This is beyond my knowledge at this point, I did try to set a global variable with no change to the error message. These are my import statements for the script: from tkinter import * from tkinter import ttk import tkFont import arcpy from arcpy import env import sqlite3 import pythonaddins I am not putting in all the code, for now it is all radiobuttons and comboboxes, very repetitive. This is the code I have concerning 'RB1': def reset():      RB1.selection_clear = var.set(0) RB1 = Radiobutton(root, text="Single Map",padx = 5, variable=var, value=1, font="Arial 9") #, state=NORMAL).place(x=10,y=60) RB1.pack() RB1.place(x=10,y=60) RB1.config(state=NORMAL) Button(root, text='Reset',width=20,bg='brown',fg='white', font="Arial 8 bold", command=reset).place(x=39,y=237) As this is my first Python script ever, and for use within ArcMap, I am sure there are a few things I am missing. Thank you for looking at my question. ... View more
