idea Add options to deal with ties in cell statistics tool when selecting the majority option in ArcGIS Pro Ideas https://community.esri.com/t5/arcgis-pro-ideas/add-options-to-deal-with-ties-in-cell-statistics/idi-p/936609 <HTML><HEAD></HEAD><BODY><P>Cell statistics is an incredibly useful tool.&nbsp; When using the MAJORITY option the default behavior of the tool for dealing with ties (when&nbsp;the two most abundant values are of equal abundance) is to create NoData.&nbsp; This will often result in a map with lots of holes (NoData cells).&nbsp; I would propose adding at least three options for dealing with ties.&nbsp; One option would be FIRST. This would take the first value of the two tied values in the raster stack.&nbsp; Another option would be LAST in which it takes the last raster of the stack with the tied value. A third option would be RANDOM. This would randomly select one of the two tied values. Finally a fourth option would be NEIGHBORHOOD. This option would expand by searching a 3x3 neighborhood and using the MAJORITY&nbsp; cell in that neighborhood.&nbsp; If a tie couldn't be broken using a 3x3 neighborhood then a 5x5 neighborhood would be used, etc. until all cells have a value.</P></BODY></HTML> Fri, 09 Aug 2019 20:19:36 GMT ThomasDilts 2019-08-09T20:19:36Z Add options to deal with ties in cell statistics tool when selecting the majority option https://community.esri.com/t5/arcgis-pro-ideas/add-options-to-deal-with-ties-in-cell-statistics/idi-p/936609 <HTML><HEAD></HEAD><BODY><P>Cell statistics is an incredibly useful tool.&nbsp; When using the MAJORITY option the default behavior of the tool for dealing with ties (when&nbsp;the two most abundant values are of equal abundance) is to create NoData.&nbsp; This will often result in a map with lots of holes (NoData cells).&nbsp; I would propose adding at least three options for dealing with ties.&nbsp; One option would be FIRST.

I would still prefer if Esri just added these options to the Cell Statistics tool itself&nbsp;<SPAN style="background-color: #ffffff;">(NODATA, RANDOM, FIRST, LAST).</SPAN></P></BODY></HTML> Fri, 09 Aug 2019 21:16:16 GMT https://community.esri.com/t5/arcgis-pro-ideas/add-options-to-deal-with-ties-in-cell-statistics/idc-p/936612#M4390 ThomasDilts 2019-08-09T21:16:16Z
