I am using ArcGIS Desktop 10.4.
I would like to create multiple ring buffers surrounding my polygon localities. My buffers should not overlap and I need to know, which location each of my buffers surrounds.
I've thought to simply use
arcpy.MultipleRingBuffer_analysis. However, if I use
Dissolve_Option = "NONE", I am able to define which locations my buffers surround, as the locations ID is stored in newly created
"ORIG_FID" field. However, my buffers overlap.
If I use
Dissolve_Option = "ALL", my buffers do not overlap. But, I have no information about which location does my buffer surround.
How do I accomplish having multiple distances non-overlapping buffers but be able to know the location they belong to?
My code to create multiple ring buffers:
# Import modules import arcpy, os # Set environmental settings inWD = "C:/Users/Localities" arcpy.env.workspace = os.path.join(inWD, "analyzed.gdb") outPath = os.path.join(inWD, "output.gdb") # Allow files to overwrite arcpy.env.overwriteOutput = True # Define input variables inFC = "NPR" try: # Define Multiple ring buffer variables distances = [100, 500, 1000, 2000] buffUnit = "Meters" Field_Name = "distance" Dissolve_Option = "ALL" Outside_Polygons_Only = "OUTSIDE_ONLY" # Process: Multiple ring buffer outBuff = os.path.join(outPath, "buff_complete") arcpy.MultipleRingBuffer_analysis(inFC, outBuff, distances, buffUnit, Field_Name, Dissolve_Option, Outside_Polygons_Only) except: print(arcpy.GetMessages(0))
Simple illustration for distances [100,500,1000,2000] Meters: even if I click only on 100 m buffer (the closest to inFC), my buffers have to overlap, as in attribute table I've selected 3 different buffers.
