same valueCalculate a statistic within the zones for each cell in a rasterInput zones can be feature or rasterOutput as a raster,summary table,or graph-Max flow length in each watershed-Median income in each ZIP CODE-Mean elevation per vegetation zoneGetting Started with Spatial AnalystMean Slope per WatershedMean Slope per WatershedEsri UC 2014|Technical Workshop|Zonal HistogramCreate histograms of cell counts within Zones-Same zone definitions as Zonal Statistics-Zones can also be classes defined in the rendererInvestigate frequency/distribution of one dataset within classes of another datasetSlope distribution within Land use classesRainfall distribution within Elevation classesCrime distribution by beatGetting Started with Spatial AnalystEsri UC 2014|Technical Workshop|Interpolation and ContouringGenerate surfaces from point measurements-Natural Neighbors-Minimum Curvature Spline-Spline with Barriers-TopoToRaster-Kriging-Polynomial Trend Surface-Inverse Distance WeightedCreate contours from surfaces-Batch GP tools-Interactive contour buttonGetting Started with Spatial AnalystEsri UC 2014|Technical Workshop|Choosing an interpolation methodYou know nothing about your data-Use Natural Neighbors.It is the most conservative.Assumes all highs and lows are sampled,will not create artifacts.Your input data is contours-Use TopoToRaster.It is optimized for contour input.If not creating a DEM,turn off the drainage enforcement option.You know the highs and lows are not sampled-Use Spline.Be careful of points that are near in space but very different in value creating unnatural artifacts.-Use Geostatistical Analyst Kernel Smoothing InterpolationYour surface is not continuous-Use Spline with Barriers if you know there are faults or other discontinuities in the surface.You want or need a geostatistical technique-Use Geostatistical Analyst Empirical Bayesian KrigingCreating Surfaces Tuesday 1:30 or Wednesday 10:15 Room 17Getting Started
