Select by location arcgis

A useful application of this behavior is to select adjacent, select by location arcgis, 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.

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.

Choose this option if the data covers a large geographic extent or the coordinate system of the inputs is unsuitable for distance calculations.

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. Features that intersect in one coordinate system may or may not intersect in another.

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.

Intersect DBMS. The distance that will be searched. Use the following steps to apply the Select By Location tool. A target feature is selected by this operator if the centroid of its geometry falls into the geometry of the source feature or on its boundaries. Only records that are common to both remain selected. This is the reverse operator from Completely contain. A, C, E. The highlighted cyan features are selected because they fall within the selected distance of the red features. The graphics are labeled A, B, C, and so on. Below is an example of expanding a selection of streets that are connected to the original selection. Have their center in.

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.

All records that were selected will be removed from the selection, and all records that were not selected will be added to the selection. Checked—The opposite of the evaluation result will be used. If polygons are used for the input or selecting layer, the polygon's boundary line will be used. This may result in slightly different selections being returned compared to when the analysis is performed on the client with an x,y tolerance applied. Click OK to execute the tool and work with your selection results. The input and selecting features must be lines or polygons. Select connected roads The approach of expanding a selection is not limited to polygon layers; it can also be used with line data. All records that were selected are removed from the selection, and all records that were not selected are added to the selection. Arc GIS Desktop. In this topic Expand selection to adjacent counties Expand selection to intersecting polygons Select connected roads.
