Hi, I am trying to build a script that combs through all shapefiles within a folder, and all it's subdivisions, and merge them together into a new shapefile. I modified it slightly from another script (sorry can't rem the source to acknowledge...). However, it prompted me this error "ExecuteError: Failed to execute. Parameters are not valid. ERROR 000400: Duplicate inputs are not allowed Failed to execute (Merge)." The script is as stated below. Can anyone tell what is wrong with it? Thank you! import arcpy, os workspace = r'C:\Users\xxx\Desktop\boundary' output_folder = r'C:\Users\xxx\Desktop\New folder' Dict = {} for root, dirs, files in os.walk(workspace):     for dir in dirs:         arcpy.env.workspace = os.path.join(root,dir)         for fc in arcpy.ListFeatureClasses():             if not fc in Dict:                 Dict[fc] = []                 Dict[fc].append(os.path.join(root,fc))             else:                 Dict[fc].append(os.path.join(root,fc)) for key in Dict:     output = os.path.join(output_folder,key[:-4]) + '_merge'     arcpy.Merge_management(Dict[key], output)     print output + " created" ...

I made a simple toolbar of 2 buttons to export the map into JPEG and PDF using Python Add-in wizard. However, I wanted to improve the script such that when I click the button, it will prompt a window to select the location to place the file, and also input the file name. Does any know how to do it? The present script is pasted below. Thanks! ----------------- import arcpy import pythonaddins class export2_jpg(object):     """Implementation for export2_jpg_addin.button (Button)"""     def __init__(self):         self.enabled = True         self.checked = False     def onClick(self):         mxd = arcpy.mapping.MapDocument('current')         arcpy.mapping.ExportToJPEG(mxd,r'C:\Users\xx\Desktop\output.jpg, resolution=300')         pass class export2_pdf(object):     """Implementation for export2_pdf_addin.button (Button)"""     def __init__(self):         self.enabled = True         self.checked = False     def onClick(self):         mxd = arcpy.mapping.MapDocument('current')         arcpy.mapping.ExportToPDF(mxd,r'C:\Users\xx\Desktop\output.pdf')         pass ...

Hi, I have created a world map in the form of a globe by defining the projection as orthographic. The feature class for display consists of the world's countries. How do I fill in the sea with a background colour for such a case? I can't use the data frame's frame tab for the defining the background colour since it will render the entire screen with that colour. Currently I have to manually create a circular feature class and set it as the background. Just wondering whether there is an easier way to accomplish the same objective. I am using ArcGIS 10.2.2 Thanks! ... View more

Hi, I have a set of symbols defined under Symbology > Unique Values, and I want to set the ranking so that the hatched symbols all appear on top of the filled ones in the map display. The arrows to assign them does not seem to do this (see print screen attached). Is this function faulty? 😕 Besides creating individual layers and arranging them in TOC, is there any other easier way to go about this? I am using 10.2.2. Thanks! ... View more

I have a model that runs a data check with an output table listing the number errors it found. I am wondering if I can complete the the model with a python statement that calls it to open the table. I know I can just right click and open the attribute table in ArcMap, but I just thought it will be cool to have a really complete model from start to end. I am using 10.2.2. Thanks! ... View more
