How does the iterate datasets tool work in ArcGIS?

How does the iterate datasets tool work in ArcGIS?

The Iterate Datasets tool iterates over datasets in a workspace or feature dataset. In the image below, the model copies all the feature datasets contained in the Input Dataset variable, a workspace variable. The iteration has been restricted to iterate only on the feature dataset type.

How to define workspaces for Geodatabases in ArcPy?

With file-based geodatabases, it includes the name of the geodatabase. SDE workspace paths are defined by the system path to the SDE connection file. A workspace type is an ArcGIS supported data model format. For example, shapefile, personal geodatabase, file geodatabase, CAD, SDE, and so on.

How to find and replace data sources in ArcPy?

A data source for a layer or table is the combination of the workspace and dataset. The findAndReplaceWorkspacePaths method on the MapDocument object is intended to perform a global find and replace of workspace paths for all layers and tables in a map document that share that workspace path.

Can a shapefile be redirected to a geodatabase workspace?

For example, a shapefile called Highways.shp can be redirected to a file geodatabase workspace only if the dataset name in the file geodatabase is also called Highways. Use the replaceDataSource method on the Layer or TableView objects if the dataset name is different.

How are iterate datasets used in ModelBuilder?

The tool has one output: the value, which is a string of feature classes connected to the Project tool as input. To understand the use of Iterate Datasets in ModelBuilder, see the illustration below, where the model copies all the feature datasets contained in the Input Dataset variable, a workspace variable.

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.

Where are rasters stored in ArcGIS ModelBuilder?

In the image below, the model creates a mosaic using rasters stored in a geodatabase named Arizona, which is stored inside a folder. The iteration has been restricted with the wildcard Ar* and workspace type of file geodatabase so that it only iterates over file geodatabases with names starting with the letters Ar.

When to use a cookie cutter in ArcGIS?

Use this tool to cut out a piece of one feature class using one or more of the features in another feature class as a cookie cutter. This is particularly useful for creating a new feature class—also referred to as study area or area of interest (AOI)—that contains a geographic subset of the features in another, larger feature class.

What are the clip features in ArcGIS for?

This is particularly useful for creating a new feature class—also referred to as study area or area of interest (AOI)—that contains a geographic subset of the features in another, larger feature class. The Clip Features can be points, lines, and polygons, depending on the Input Features type.

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.

Which is the output of Arc feature classes?

ARC —Only arc features classes will be the output. DIMENSION —Only dimension feature classes will be the output. EDGE —Only edge feature classes will be the output. JUNCTION —Only junction feature classes will be the output. LABEL —Only label features classes will be the output. LINE — Only line feature classes will be the output.

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.

Why is iterator only iterate on block polygons?

The iteration has been restricted by choosing the POLYGON feature type; therefore, the iterator only iterates on the Block and Parcel polygon feature classes. The tool has two outputs:

How does the iterate rasters tool work in Excel?

The Iterate Rasters tool iterates over rasters in a workspace. In the image below, the model resamples grid datasets and extracts a subset for further analysis. The Input Rasters variable is a folder containing grids, images, and TIFFs.

How are feature types used in ArcGIS workspace?

Feature Type limits the feature classes by their feature types: annotation, arc, dimension, edge, junction, label, line, node, point, polygon, region, route, or TIC. The Recursive parameter is used to control the iteration over feature classes within subfolders in the workspace.

How does iterator in ModelBuilder work in gdb?

The iteration has been restricted with the wildcard Ar* and workspace type of file geodatabase so that it only iterates over file geodatabases with names starting with the letters Ar. Output Workspace variable, containing Arizona.gdb, is connected to the Workspace To Raster Dataset tool as input.

What does the recursive parameter do in ArcGIS?

The Recursive parameter is used to control the iteration over feature classes within subfolders in the workspace. Iterate Feature Classes has two output variables: the output feature class and the name of the feature class.
