Which is an example of an iterator in model builder?

This can be done with a combination of tools in Model Builder. A basic example would be using an iterator to iterate through the different grid features (grouped by a value from the attribute table) and uses that feature to select form a different layer those features that intersect it.

How to select by location in model builder?

In Model Builder, first you have to convert your feature class to feature layer with ‘Make Feature Layer’ function, and then you can perform the ‘Select by Location’ function, with intersect option, or any other, or add a join… The ‘Select By Attribute’ function, you can perform it directly on your Feature class with the ‘Select (Analysis)’ tool.

How does the iterate feature selection tool work?

The Get Count tool checks to see if there are any selections that match the criteria set in the Make Table View tool. While ensures that the model runs until the row count is not zero. The Iterate Feature Selection tool iterates over features in a feature class.

How are iterators used in zonal statistics as table?

Selected feature (connected as input to the Zonal Statistics As Table tool). The Value variable, which contains the name of the feature (based on the grouping field) used as an inline variable in the output name of the Output Table variable. The Iterate Row Selection tool iterates over rows in a table.

How is iterate MultiValue used in ModelBuilder?

To understand the use of Iterate Multivalue in ModelBuilder, see the illustration below, where the model changes the map projection of several feature classes stored in different drives and workspaces. The projected output feature classes are written to a single output database.

How is iterate row selection used in ModelBuilder?

To understand the use of Iterate Row Selection in ModelBuilder, see the illustration below, where the model creates a deviational ellipse for theft incidents during different periods of the day—morning, afternoon, evening, and night—to detect an underlying pattern of crime.
