In today\u2019s blog post, I would like to share with you some best practices about using the Reclassify<\/a> tool in ArcGIS Pro. Reclassification is the process of reassigning one or more values in a raster dataset to new output values. The Reclassify tool is available in the Spatial Analyst extension in both ArcMap and ArcGIS Pro. When we built the Reclassify tool for ArcGIS Pro, we included a longstanding request to have the tool recognize the class breaks from the input layer symbology. Here I will introduce the improved reclassification workflow in ArcGIS Pro. For those who are used to working with ArcMap, there are some differences. It is therefore also my goal to clarify some questions about the Reclassify tool when migrating from ArcMap to ArcGIS Pro.<\/p>\n

There are many reasons to reclassify raster data. For example, you may want to group together various types of forest into one forest class to simplify the information in the raster or you want to set specific values to NoData to exclude them from analysis. Another application is Suitability Analysis where the Reclassify tool is used to transform values of various input raster datasets to a common scale.<\/p>\n

A regular workflow for users in ArcMap was to begin with symbolizing a raster layer with different classification algorithms for display. After visualizing the layer and being satisfied with the classification settings, users would then open the Reclassify tool and use the \u201cClassify\u201d option to recreate the preferred classification and class breaks. The improvement in ArcGIS Pro is that the classification of the current layer symbology is used automatically to populate the default classification in the Reclassify tool.<\/p>\n

We have also received feedback that some of our users still prefer to see a \u201cClassify\u201d button on the Reclassify tool to launch the additional classification methods, a histogram chart and stats. The good news is that it will be included in an upcoming ArcGIS Pro release.<\/p>\n

Now let\u2019s address some of the questions raised by our users about the Reclassify tool in ArcGIS Pro:<\/p>\n"},{"acf_fc_layout":"content","content":"
