The Select By Location tool lets you select features based on their location relative to features in another layer. For instance, if you want to know how many homes were affected by a recent flood, you could select all the homes that fall within the flood boundary. You can use a variety of selection methods to select the point, line, or polygon features in one layer that are near or overlap the features in the same or another layer. Use the following steps to apply the Select By Location tool. Note that you select features from a layer or a set of layers that have a spatial relationship with features from a source layer. For example, select features from USA Counties that touch the boundary of the features in the layer named "Texas. See Types of supported spatial queries below for an overview of the selection options. The following spatial query methods are supported using Select By Location. In these descriptions, the Target layer is the layer in which features are selected. The Source layer is the layer whose features are used to determine the selection based on its spatial relationship to the target. In the diagrams, selected features are highlighted in cyan where they intersect, touch, or are contained within the red source features, and so on.

Selects features in a layer based on a spatial relationship to features in another layer. Each feature in the Input Feature Layer is evaluated against the features in the Selecting Features layer or feature class; if the specified Relationship is met, the input feature is selected. Graphic examples of relationships. The input must be a feature layer ; it cannot be a feature class. The coordinate system in which the spatial relationship is evaluated may affect the result.

Selects features based on a spatial relationship to features in another dataset or the same dataset. Each feature in the Input Features parameter is evaluated using the features in the Selecting Features parameter. If the specified Relationship parameter value is met, the input feature is selected. Learn more about Select By Location including image examples of relationships. If the input is a feature class or dataset path, this tool will create and return a new layer with the result of the tool applied. The coordinate system in which the spatial relationship is evaluated can affect the result.

Selects features in a layer based on a spatial relationship to features in another layer.

Graphic examples of relationships. The input must be a feature layer ; it cannot be a feature class. The coordinate system in which the spatial relationship is evaluated may affect the result. Features that intersect in one coordinate system may or may not intersect in another. This tool evaluates a spatial relationship in the coordinate system of the Input Feature Layer data source the feature class on disk. Set the output coordinate system environment to evaluate the spatial relationship in a different coordinate system.

How to use Select By Location Remember that when you select features from a layer, they must have a spatial relationship with features from a source layer. For details of how the Relationship options differ, see Select By Location: graphical examples. The operator includes the Clementini operator but also expands it. For all the examples below, the following legend applies:. The coordinate system in which the spatial relationship is evaluated can affect the result. Learn more about Select By Location including image examples of relationships. Within a distance 3D. To be selected, the geometry of the source feature must fall inside the geometry of the target feature including its boundaries. A, C, D, E. If one of the features is a polygon, an additional requirement is that no part of the geometry of the other feature can be completely within the geometry of the polygon. Completely within — The features in the input layer will be selected if they are completely within or contained by a selecting feature.

The Select By Location tool lets you select features based on their location relative to features in another layer. For instance, if you want to know how many homes were affected by a recent flood, you could select all the homes that fall within the flood boundary.

If the Within a distance geodesic option is selected, use a linear unit such as kilometers or miles. From Python , the number of selected records can also be accessed from the tool's Result object. Specify the selection method if you want to change how the selection is applied and what to do if a selection already exists. In this topic How to use Select By Location. See Types of supported spatial queries below for an overview of the selection options. This operator provides the same results as Are Within unless the Target feature is entirely on the boundary of the source feature, with no part of the target feature inside the source feature. SelectLayerByLocation example 2 stand-alone script The following stand-alone script shows how to use the SelectLayerByLocation function in a workflow to extract features to a new feature class based on location and an attribute query. For example, using this operator, Montana is selected even if its boundaries partly overlap that of the country. The features in the Input Features parameter will be selected based on their relationship to the features from this layer or feature class. Intersect 3D — The features in the input layer will be selected if they intersect a selecting feature in three-dimensional space x, y, and z. The following example expands the selection from a single county to select the adjacent counties, then the operation is repeated two times. F, G, H, M.
