Arc GIS 10.1 Set Unique identifier field

Hello, I wanted to perform a Grouping Analysis in ArcGIS 10.1. When opening the analysis tool and trying to select a unique ID field the entries where all blanck. I therefore thought, that mayber the unique identifier field wasn't set. Searching the Arc GIS Help Ressources I found this site that tries to explain how to set the Unique Identifier.… (Show more Show less)

This was asked long ago, but I just ran across the same problem. My fix is very roundabout, but it did work. It only works for point feature classes and assumes that you want to use sequential integers starting at 1, but just in a different order than the ObjectID you have already. Use the Add XY Coordinate tool to add coordinates to your…

How the GWR count their Weight?

Hello! My study is about evaluating the correlation between flower production and weather parameters. My data are taken from 2015 - 2018 in form of point data. The point data is the greenhouse location, which only includes 9 greenhouses. In each greenhouse has 400 attribute data (flower production and weather parameters) observed within weeks… (Show more Show less)

Kriging vs Spline with Barriers

Hi, I'm Jeniffer Soto from the Biogeochemistry group at USGS. We want to create a prediction surface for different water quality parameters along the Sacramento-San Joaquin Delta. Predictions are currently being completed using Kriging/Cokriging (we determine which is the best method using the summary report), and Spline with barriers. These… (Show more Show less)

Regression/OLS for point data?

I have been looking around online and whenever I see reference to OLS or GWR, few to no one using point (x,y) data in their tutorials. Why is this and is there a way to do a "what is the relationship between these variables" analysis without attaching the x,y point data to polygons. I am comfortable making grids or associating individual points… (Show more Show less)

You can absolutely run regression analysis in ArcGIS on point data. You will need a dependent variable and explanatory variables for every point.

Using the Forest based classification and regression tool, will there always be created a new trained model with every prediction or is the first one automaticily used?

When creating a prediction, i wonder where to use the output with the trained test data to generate a predicton of the actual data. So, will there be always created a new model and used on the actual data or is it stored in the background and used when creating a prediction without specifing the model to use? If i want to use the trained model for… (Show more Show less)

Optimized Hotspot Analysis tool failing when Cell Size is set

I just updated to ArcGIS Pro 2.3.2. The Optimized Hotspot Analysis tool is giving me the following error. I've been running the same parameters for a few months now and this is the first time I've had this issue, and only after upgrading. Is there a way to fix this? Parameters Input Features PresentGMI2019 Output Features… (Show more Show less)

Projecting the data has fixed the issue, though I'm still not sure why. I'm only running the tool on a single city with the city boarder bounded, roughly 20x25 square miles, and the tool ran successfully when the cell size was not set. Which probably would have been fine, except for there being no cell size consistency between several maps I…

Collecting Moran's I output values

I am running an iterator in model builder that ultimately takes the output from each iteration (a point feature class) and runs the spatial auto-correlation tool (global Moran's I). I have about 450 output feature classes, and what I would like to have is the feature class name, index value, z-score, and p-value from each iteration (of Moran's I)… (Show more Show less)

This is working beautifully. Thanks so much. I haven't made the whole process very elegant yet, but you've helped me get exactly what I need for now. I'm using a slightly cumbersome method to get the new lines to work. Instead of the chr(10) newline, I just added a semi-colon to separate the results. Then I open the text file with all the…

Unnamed error with Optimized Hot Spot Analysis, v 10.5.1

Hi, I am trying to run an Optimized Hot Spot Analysis in ArcMap version 10.5.1. This tool worked for me a couple of weeks ago but now there is an error icon next to the Input Features (screen shot attached) and no matter what input layer I select (projected/unprojected/shapefile/feature class etc.) the error does not go away. It doesn't provide… (Show more Show less)

How to normalize feature data between 0-1 in ArcGIS Pro?

Hi, I have a feature table, and want to normalize the data in a field between 0-1, and I know the normalization method should be "(x-min(x))/(max(x)-min(x) ". I have tried "add field---field calculator", but I have no idea how to use the functions. Could anyone help me to achieve it in ArcGIS Pro? Thanks
