You can try searching each band. And no it shouldn't matter if it is in a GDB or not, but I can't speak to every raster format possible. I'm sure some formats don't support this. Give this a try, assuming you are dealing with bands 1,2,3. bands = ['Band_1', 'Band_2', 'Band_3'] for band in bands:     desc = arcpy.Describe(os.path.join(raster, band))     desc.noDataValue ...

It is sql then....'''{0} < 0'' ... fascinating. If the condition is less then 0 then ...go forward... with the .format command? It is just simple string substitution. The format method is just inserting the delimited OID field name. It's broken onto two lines to ease readability. template_query = '''{0} < 0'''.format(arcpy.AddFieldDelimiters(input_fc, arcpy.Describe(input_fc).OIDFieldName)) https://docs.python.org/2/library/string.html#format-string-syntax ...

Yes that should allow you to reference it within the class using self. ... View more

It's for constructing a query that returns no results. It's the quick and dirty way of creating an empty template from an existing feature class. ... View more

You are trying to reference it at the class level without using self which won't work. You need to pass self to the function so the class can reference it, declare it within another function, or reference it outside the class. ... View more

Just trying to follow...you mean use an InsertCursor instead of SearchCursor? No, you will need to create an empty output feature class template based on your source feature class. Here is how I do it. You may want to use some field mapping depending on if you need to limit the fields from source to output. template_query = '''{0} < 0'''.format(     arcpy.AddFieldDelimiters(input_fc, arcpy.Describe(input_fc).OIDFieldName)) arcpy.TableToTable_conversion(input_fc, out_dir, output_fc, template_query) Then for each row you want in your output, you put it directly in the output with the insert cursor. Maybe something like this all together. import arcpy def find_overlaps(input_features, output_features):     template_query = '''{0} < 0'''.format(         arcpy.AddFieldDelimiters(input_features, arcpy.Describe(input_features).OIDFieldName))     arcpy.FeatureClassToFeatureClass_conversion(         input_features, out_dir, output_features, template_query)     field_list = ('OBJECTID', 'SHAPE@', 'name')     with arcpy.da.InsertCursor(input_features, field_list) as insert_cursor:         uniqueList = []         for row in arcpy.da.SearchCursor(input_features, field_list):             for shape in uniqueList:                 if row[1].equals(shape):                     foundMatch = True                     break             if not foundMatch:                 insert_cursor.insertRow(row)                 uniqueList.append(row[1]) ...

Yes you will need to make your features a layer of some sort before you copy them out. It will not accept a raw list of features as tuples. A better way to go about this might be to use an insert cursor. ... View more
