Fills in NoData values with the majority value in a 5 by 5 neighborhood for categorical data. The Focal Statistics tool employs overlapping neighborhoods to calculate a specified statistic for the cells within a specified neighborhood around each input cell. Reclassify Raster Data in ArcGIS Pro Spatial Analyst Extension In today’s blog post, I would like to share with you some best practices about using the Reclassify tool in ArcGIS Pro. Calculating neighborhood statistics is useful for obtaining a value for each cell based on a specified neighborhood. The default neighborhood is a square NbrRectangle with a width and height of 3 cells. Smooths an elevation raster in a 3 by 3 neighborhood using mean value. Performs either a smoothing (Low pass) or edge-enhancing (High pass) filter on a raster. In this analysis, we fetch housing districts of the state and add variables that provide us with total population and population density (as of 2019) for each housing district. Specify the type of statistics to calculate. Calculates a statistic on the attributes of lines in a circular neighborhood around each output cell. Calculates the average value of the pixels within the neighborhood. For more information about the methods and band orders used with this function, see the Statistics raster function. Neighborhood tools create output values for each cell location based on the location value and the values identified in a specified neighborhood. The ArcGIS Spatial Analyst extension provides a rich set of spatial analysis and … Share spatial and business analytics, publish demographic and consumer insight dashboards, apply location intelligence to your decision-making, and develop repeatable workflows that link common tasks together with ArcGIS Business Analyst Enterprise. The referenced raster dataset for the raster object is temporary. For each central pixel ArcGIS calculates the difference between the highest and lowest values in the defined neighborhood area and assigns it to the central pixel. MAJORITY — Determines the most frequently occurring field value in each neighborhood. This tool is particularly useful for changing the resolution of a raster to a coarser cell size. Calculates the maximum value of the pixels within the neighborhood. In the case of a tie, the lower value is used.
