Select by location arcgis

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, select by location arcgis. The input must be a feature layer ; it cannot be a feature class.

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.

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. Features that intersect in one coordinate system may not intersect in another. This tool evaluates a spatial relationship in the coordinate system of the Input Features data source. Set the Output Coordinate System environment to Current Map [Layers] to use the same coordinate system as the current display. To select features based on their spatial relationships to other features in the same layer, see the examples in Select based on spatial relationship within the layer. The number of selected records will be listed in the geoprocessing history. Additionally, the Get Count tool can be used to count the number of selected records. From Python , the number of selected records can also be accessed from the tool's Result object. When applying selections, a selection of zero records is possible.

Set the Output Coordinate System environment to Current Map [Layers] to use the same coordinate system as the current display.

Frequently asked question. Frequently asked question What does each of the Select By Location methods mean? Last Published: April 25, A variety of selection methods can be used to select the point, line, or polygon features in one layer that are near or overlap the features in the same or another layer. Click 'show me' for information on each selection method.

A useful application of this behavior is to select adjacent, connected, or nearby features within a layer. Different Relationship options can be used to generate the desired analysis or result. For details of how the Relationship options differ, see Select By Location: graphical examples. A loop inside a script or For and While iterators in ModelBuilder can be used in conjunction with this approach to expand a selection based on a number of iterations or until some criterion is met. One common criterion is expand until no new features are added to the selection. The Get Count tool can be used to establish when the number of selected features stops changing therefore stops growing. Below are some examples of analysis performed using this functionality with different types of data and relationship options. The following example expands the selection from a single county to select the adjacent counties, then the operation is repeated two times. The example below uses the Intersect relationship to expand a selection from two origin points. The approach of expanding a selection is not limited to polygon layers; it can also be used with line data.

Share a line segment with — The features in the input layer will be selected if they share a line segment with a selecting feature. For example, using this operator, the state of Montana is selected even if it shares boundaries with the United States. A, C, D. Within a distance 3D. The coordinate system in which the spatial relationship is evaluated can affect the result. In this case, using the Contain Clementini operator does not select the target feature, whereas the Contain operator does. In addition, the source feature cannot touch or overlap the target's boundaries. See Feature class basics for more information about how an x,y tolerance is applied during client-side operations. A, B, C, E. Crossed by the outline of. The highlighted cyan features are selected because they completely contain the red features. The Select By Location tool allows you to select features based on their location relative to features in another layer. Usage 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. A loop inside a script or For and While iterators in ModelBuilder can be used in conjunction with this approach to expand a selection based on a number of iterations or until some criterion is met.

The highlighted cyan features are selected because they completely contain the red features. The Select By Location tool allows you to select features based on their location relative to features in another layer. The Search Distance parameter is not set. This topic covers examples and expected results of the Relationship parameter options available in the Select Layer By Location tool as well as the Spatial Join tool. For instance, when using this operator, Wyoming is completely within the United States but Montana is not, as its northern boundaries overlap that of the country. Distance between features will be calculated using a geodesic formula that takes into account the curvature of the spheroid and correctly handles data near and across the dateline and poles. Existing selections prior to running the tool were made using a layer definition query, not a selection set. Clementini states that a polygon's boundary is separate from its inside and outside. The selection will be processed in the enterprise geodatabase DBMS rather than on the client when all requirements are met see usage notes. Boundary touches. The source and target features must be either lines or polygons. For example, this option can be used to quickly get a list of features that do not intersect or are not within a distance of features in another dataset. The feature types must be the same.
