There are so many resources on the Internet that can help you to learn Python, it is to much to mention. One way is to do a search in GeoNet: https://community.esri.com/search.jspa?q=learn+python  or just Google it. You will find a large number of post with lots of like to different sites like: Dive Into Python Learn Python If you are willing to pay for a book, then this post references a very good book: Re: Any Good Python Books I have posted some Python Snippets that might help: Some Python Snippets  ...

Indeed the region group tool is a method to obtain the result.+1 for that! ... View more

I converted the PDF to raster, changed the raster, did some vectorization and made some edits (added some additional water points). The unpolished code I used I included below. It creates a list of OID's of the fence areas Loops through the list of OID´s creates a featurelayer with only the current fence area based on OID creates a featurelayer with only the water points in that area creates the multi ring buffer on those points clips the resulting buffers with the area import arcpy, os fc_pnt = r"C:\Forum\Pasture\test.gdb\waterpoints" fc_pol = r"C:\Forum\Pasture\test.gdb\FenceAreas" ws = r"C:\Forum\Pasture\test.gdb" arcpy.env.overwriteOutput = True dists="25000;50000;75000;100000;125000;150000;175000;200000" fld_oid = arcpy.Describe(fc_pol).OIDFieldName lst_OIDs = [r[0] for r in arcpy.da.SearchCursor(fc_pol, "OID@")] for oid in lst_OIDs:     where = "{0} = {1}".format(arcpy.AddFieldDelimiters(fc_pol, fld_oid),oid)     arcpy.MakeFeatureLayer_management(fc_pol, "flpol", where_clause=where)     arcpy.MakeFeatureLayer_management(fc_pnt, "flpnt")     arcpy.SelectLayerByLocation_management("flpnt", 'intersect', "flpol")     fc_buf = os.path.join(ws, "buf_{0}".format(oid))     arcpy.MultipleRingBuffer_analysis(Input_Features="flpnt",Distances=dists,                                       Output_Feature_class=fc_buf,Buffer_Unit="Default",                                       Field_Name="distance",Dissolve_Option="ALL",                                       Outside_Polygons_Only="FULL")     fc_bufclip = os.path.join(ws, "buf_{0}clip".format(oid))     arcpy.Clip_analysis(fc_buf,"flpol",fc_bufclip)     # ... also merge the buffer layers into a single featureclass ...

Yep, Cost Distance is the best way to get the desired result. Just attach a piece of your data and I'll show you how to get the result. ... View more

If the fields in the featureclasses are all named the same, I guess you don't have to use field mapping... You could simply merge the featureclasses together and then remove any redundant fields... ... View more

I assume you have Corel Draw. If so you have several formats that can be used as intermediate format that Corel Draw can import. You may want to read this thread: vector - Export shp spatial data to Corel - Geographic Information Systems Stack Exchange I suppose converting to EMF, EPS, SVG or AI could also work. ... View more

If you're willing to share (part of) the data, I'm sure things will become clearer and that will allow us to come up with a solution. Please also provide info on the versión of ArcGIS and if you hace access to the Spatial Analyst extension. ... View more

If you have some sample data that follows the structure you want to use, I can see if I can come up with a script to process the 110 pastures. ... View more

You're welcome. Glad it worked! ... View more

When it creates the output featureclass it is taking the input featureclass as the spatial reference. The error indicates that the featureclass is not valid to extract the spatial reference from. What did you specify as input featureclass? Does it have a spatial reference (=coordinate system)? ... View more

Simply drag the window;  locate the mouse on the blue title bar, drag the window until you see the anchor points appear and locate the window for instance to the center left anchor to make it appear as the left column of the window. ... View more
