I'm at the stage where I'm looking to clean the data and get it ready for migration. We currently store data in two feature classes: a line feature class for drawing the registered plans and a polygon feature class, built from those lines, containing the parcel shapes. The bad news is that at some point in the past a lot of the arc data has been converted from being an actual arc to being multisegmented lines:</P><P><IMG alt="DfRCC.png" class="image-1 jive-image" src="http://i.stack.imgur.com/DfRCC.png" style="width: 620px; height: 442px;" /></P><P><SPAN style="font-size: 8pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Example of a parcel created from the multisegmented lines instead of arcs.</SPAN></P><P></P><P><SPAN style="font-size: 12pt;">The good news is that these lines contain the data needed for reconstructing the arc:</SPAN></P><P><SPAN style="font-size: 12pt;"><IMG alt="79gaS.png" class="image-2 jive-image" src="http://i.stack.imgur.com/79gaS.png" style="width: 620px; height: 111px;" /></SPAN></P><P><SPAN style="font-size: 8pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Attribute table for the lines - Most lines and arcs (actually multisegmented lines) are their own individual feature and contain the arc data.</SPAN></P><P></P><P>I've used tools/add-ins to recreate the arcs from the line geometry data only, but the resulting fit is not great.</P><P>My question is this: <STRONG>Can these arcs be recreated from the data contained in the attribute table?</STRONG> Can I draw arcs using arcpy? I haven't been able to find anything to suggest I can. Am I going about this the wrong way maybe? Geoprocessing tools, python solution ideas.. anything is welcome.</P><P>I've also asked this question over at <A href="http://http//gis.stackexchange.com/questions/183823/redrawing-multisegmented-lines-as-arcs-using-measurements-stored-in-attributes">StackExchange - GIS</A>​ but with no luck.</P><P><A href="https://community.esri.com/migrated-users/25185">Ben Van Kesteren</A>​</P></BODY></HTML> Tue, 08 Mar 2016 22:42:12 GMT https://community.esri.com/t5/land-records-and-valuation-questions/redrawing-multisegmented-lines-as-arcs-using/m-p/853016#M461 NathanDuncan 2016-03-08T22:42:12Z Re: Redrawing multisegmented lines as arcs using measurements stored in attributes https://community.esri.com/t5/land-records-and-valuation-questions/redrawing-multisegmented-lines-as-arcs-using/m-p/853017#M462 <HTML><HEAD></HEAD><BODY><P>Actually, don't believe the attribute table has all COGO details you'd need to recreate arc's from the cord's.
