Calculating the centroid of each polygoin, but weighted by points from another layer

Hi All, I'm trying to get the centroid of each polygon in the attached image, but I want the centroid calculation to be based on the clusters of green dots in each polygon. The purple polygons are from one layer and the green dots are from another layer. How can I do this? How can I calculate the centroid of each polygon based on the clusters of… (Show more Show less)

Why do we get different COtypes or outliers on repeating the "Optimized Outlier analysis" and "Cluster and Outlier analysis"

Hi all, I am new to ArcGIS and am looking to find outliers (high and low) in my data. The variable I am using is a disease severity variable ranging from 0 to 60 (i.e. my analysis field). I am trying to find outliers in this variable. However, I recently figured that each time I run the Optimized outlier analysis or the cluster and outlier… (Show more Show less)

Count of majority value for each cell?

I ran 10 classifications (Random Trees) in ArcMap. Each time the output will be somewhat different. I have made a final map based on the majority value of each pixel using cell statistics (majority). I have also produced a map where the number of different class values is reported using cell statistics (variety). Now I want a map… (Show more Show less)

Are you more likely to use ArcGIS Pro or ArcMap for your day-to-day work?

I've been working with various clients to migrate from Map to Pro, and am trying to get an idea of the consensus in the GIS community regarding which one is used more often. arcpro arcgispro arcgis arcmap arcmap

KKramer-esristaff mentioned Spatial Statistics 2 months ago

That is true. There are many other places where the poll would be relevant. Like Analysis Network Analyst ModelBuilder Spatial Statistics etc. Many users who participate in those parts of the GeoNet Community may use either ArcMap, or ArcGIS Pro, or both, and it would be insightful to hear about their experiences.Preview Hide preview

Error 000539 when filling NoData values using Raster Calculator FocalStatistics

I have a global ocean pH raster map.The raster has large NoData areas: all land areas and many coastlines have NoData. The land areas should remain as NoData, but the ocean areas (blue) should be filled with pH values. First I made a seperate map with all the ocean areas that need to be filled (black=1, white=NoData): Then I tried to… (Show more Show less)

Hi, Let's try this code: Con("%pH_GapsToBeFillled%"==1, FocalStatistics("%pH_Global%", NbrRectangle(10,10, "CELL"), "MEAN",""), "%pH_Global%") I added a ("") at the end of FocalStatistics function to set "Not ignore NoData". Also, you may want to set your workplace by arcpy.workspace function. I hope this helps.

Are there any alternatives to GWR for small datasets ?

Hi, I'm working with a dataset including 29 territories. I have run GWR and prediction models in the past and would like to evetually run something similar here but knowing that GWR is not appropriate for small datasets, I was wondering if there exists an alternative to GWR for small datasets?

Guidance on Optimized Hotspot Analysis

I am using the Optimized Hotspot Analysis tool in ArcGIS Pro to identify clustering of high and low values in my incident point data. After running the tool iteratively for multiple input point datasets, I have noticed that the cell sizes and distance bands used vary per iteration. I can understand that this is because the number of points and… (Show more Show less)
