The result is a raster line with a "PATHCOST" field telling me the cost of following that route. </SPAN><BR /><BR /><SPAN>I want to convert this raster line to a vector polyline so I use the 'raster to polyline' tool under 'Conversion Tools'. </SPAN><BR /><BR /><SPAN>They have a handy optional "Field" prompt which allows the user to specify which raster field gets to become part of the new polyline attribute table. </SPAN><BR /><BR /><SPAN>For some reason, that "PATHCOST" field in the raster line, the only one I need, is the only field that does not show up as one of the field options.. so Its not even available for me to select it. </SPAN><BR /><BR /><SPAN>I dont know why this is happening, has anyone run into this before, maybe someone has an idea how I can make this field available to me??</SPAN><BR /><BR /><SPAN>I have been advised that another way of getting the 'cost' of following that specific route may be to use zonal statistics under spatial analyst - but the output there is a raster, when I want my end product to be a vector polyline with the pathcost field. </SPAN><BR /><BR /><SPAN>Please let me know if you have any ideas and thanks so much in advance.</SPAN></BODY></HTML> Tue, 11 Jun 2013 19:29:30 GMT https://community.esri.com/t5/geoprocessing-questions/conversion-raster-to-polyline-pathcost-field-not/m-p/593776#M19670 ShinoRah 2013-06-11T19:29:30Z Re: Conversion: Raster to Polyline.. pathcost field not available. https://community.esri.com/t5/geoprocessing-questions/conversion-raster-to-polyline-pathcost-field-not/m-p/593777#M19671 <HTML><HEAD></HEAD><BODY><SPAN>Your raster is integer and does have a table?</SPAN></BODY></HTML> Wed, 12 Jun 2013 14:20:17 GMT https://community.esri.com/t5/geoprocessing-questions/conversion-raster-to-polyline-pathcost-field-not/m-p/593777#M19671 SteveLynch 2013-06-12T14:20:17Z Re: Conversion: Raster to Polyline.. pathcost field not available. https://community.esri.com/t5/geoprocessing-questions/conversion-raster-to-polyline-pathcost-field-not/m-p/593778#M19672 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote">Your raster is integer and does have a table?</BLOCKQUOTE><BR /><SPAN> </SPAN><BR /><SPAN>Right.
