How does iterate feature selection in ArcGIS work?
For each iteration, the selection of the output feature layer is determined by the number of records that match the given combination of the group by fields. If more than one group by field are chosen, then the values are concatenated _ in the output inline variable name.
How are iterators used in ModelBuilder Pro Pro?
The iteration has been restricted to iterate only on the feature dataset type. Dataset (Land and Transportation). Name, which is used as the inline variable %Name% in the output of the Copy tool. The Iterate Feature Classes tool iterates over feature classes in a workspace or feature dataset.
How is the number of iterations determined in ArcGIS?
If one or more group by fields are selected, the number of iterations is determined by the number of unique combinations of the group by fields. For each iteration, the selection of the output feature layer is determined by the number of records that match the given combination of the group by fields.
How is iterate feature classes used in ModelBuilder?
Name, which is used as the inline variable %Name% in the output of the Copy tool. The Iterate Feature Classes tool iterates over feature classes in a workspace or feature dataset. In the image below, the model finds the population density for the Blocks and Parcels feature classes in the Input Feature Classes variable.
How is the temporary feature layer saved in ArcGIS?
The temporary feature layer can be saved as a layer file using the Save To Layer File tool or saved as a new feature class using the Copy Features tool. If an Iterator is added to a model, all tools in the model iterate for each value in the iterator.
What happens when you add an iterator to a model?
If an Iterator is added to a model, all tools in the model iterate for each value in the iterator. If you do not want to run each tool in the model for each iterated value, create a sub-model/model within a model/nested model that contains only the iterator and add it as a model tool into the main model.
Can you use the output selected features in ModelBuilder?
The output Selected Features is a feature layer and can be used in other geoprocessing tools that accept a feature layer in ModelBuilder. Complex feature classes, such as annotation and dimensions, are not supported by this tool. More than one group by field can be used for the selection.
