arcpy query layer

There are many properties available in the ArcMap Layer Properties dialog box that are not exposed to the arcpy scripting environment (for example, display properties, field aliases, selection symbology, and so on). The default value is NONE which turns off layer extrusion. First, you can check to see if the layer supports the isGroupLayer property. import arcpy schoolsLayer = "Schools" suburbsLayer = "Suburbs" # get an update cursor as we will be changing values rows = arcpy.UpdateCursor(suburbsLayer) # loop through each suburb in the layer for row in rows: polygon = row.SHAPE arcpy.SelectLayerByLocation_management(schoolsLayer,"INTERSECT",polygon) Provides the ability to get or set the transparency value. Server —Property displaying the server name. To clear the maximum scale, set the value to 0. The layer object provides access to many of the common layer properties found in the ArcMap Layer Properties dialog box and it also provides methods for saving layer files. There are two methods on the Layer object that help with this. Property displays the description title string for the WMS service. This gives Python script authors control over the CIM version that will be used during execution if there is a possibility that breaking changes may be introduced in the new version. Spaces can be included. In these cases, you may need to test other properties to isolate a layer of interest before doing something to it. The following script tests if a layer file supports time and if time properties have been set. Setting metadata is dependent on the isReadOnly property value. The layer file contains a custom color ramp that is applied to the layer. The following script will print the name of each SDE or web service layer along with the appropriate service information. Feature layer query . Example two below shows how you can formulate a time query using the time field and select a set of features based on time and then save those features to a separate feature class. Layer types that support the showLabels property also support the labelClasses property. Title —WMS service layers only. It includes the workspacePath and the datasetName properties combined. A layer's path including the group layers it may be nested within. It is good practice to first test the layer's symbologyType property. The replaceDataSource method allows you to change a layer's workspace and source dataset. This function is intended to be used in a web tool that uses the ConvertWebMapToArcGISProject function in web map printing applications that support changing the renderer (or other properties) of dynamic web service layers. WMSName —WMS service layers only. Returns a layer's data source connection information as a Python dictionary. All layer types support this property. If dataset_name is not provided, the replaceDataSource method will attempt to replace the dataset by finding a table with a the same name as the layer's current dataset property. A value of True will return the layer's symbolized extent; otherwise, it will return the geometric extent. Extrusion is the process of vertically stretching a flat 2D shape to create a 3D object. Python Sets or Lists can be used for the oidList but sets get returned from the getSelectionSet method on the Layer object. If you want to create an application that can access feature layer data you can use the ArcGIS REST API and the query operation. A layer's longName value will include the group name in addition to the layer name. Either your script can check the ServiceType key before evaluating specific keys or you can use the get method that allows you to bypass keys that are not available. There are numerous types of layers and not all of them support the same properties. If set to False, the method will set the source to match the workspace_path, regardless of a valid match. URL —Property displaying the URL to the service. The ListLayers function returns index values that are generated from top to bottom as they appear in the table of contents or the way they appear in a layer (.lyr) file. Querying features using a different spatial reference ¶ In [26]: query_result1. Rather than having to work with different, individual layer objects for all possible layer types and property combinations, a supports method is available to help identify which layer types support which individual layer properties. the ExportWebMap JSON specification for more A Python list of Object IDs to use along with the appropriate selection method. Not all layer properties are accessible through the Layer object. Type a plus or minus sign to the left of the value to specify whether it is above or below 0. UserName —Property displaying the user name used to access a secured service. It gives you the ability to test if the layer supports a property before trying to get or set its value, reducing the need for additional error trapping. In these cases you may need to test other properties to isolate a layer of interest before doing something to it. For more information and a code sample, see ConvertWebMapToArcGISProject. A layer's brightness value. A string that represents the workspace path or connection file you want to replace. Finds and replaces a layer's workspace path with a new workspace path. In this page, we are going to observe how the following can be accomplished: Import libraries Note: Python Lists are used for setting the oidList but Python Sets get returned from the getSelectionSet method on the Layer object. # arcpy. Sets a layer's selection using a Python list of Object IDs. Returns True if a layer is a group layer. Next, it verifies that the layer has graduated color symbology. OTHER —A string that represents an unsupported layer symbology class. If your geoprocessing services replaces the service layers with staged vector layers after running ConvertWebMapToMapDocument, updateLayerFromJSON will apply the renderer (or other layer properties) as specified in the webmap_json to the corresponding vector layers staged in the template map document. Returns True if a layer is an ArcGIS Network Analyst extension layer. A z-value is calculated for each vertex of the feature's base, and the feature is extruded to the various z-values creating a multifaceted top. Returns a reference to the layer's symbology class. Replaces connection properties using a dictionary or a path to a workspace. The query can be used to join several tables or return a subset of fields or rows from the original data in the database. Use values between 0 and 100. A layer's contrast value. UserName —A user account. There are essentially three categories of layers in a map document: feature layers, group layers, and raster layers. The following script modifies the symbology for a layer in a map document. If it is not valid, the connection will not be replaced. Returns a layer's selection as a Python set of object IDs. For example, a layer named Layer1 in a group layer named Group1 will have a longName value of Group1\Layer1. It can either reference layers in a map document (.mxd) or layers in a layer (.lyr) file. Returns True if a layer will cause rasterization of other vector layers in the data frame when the map is printed or exported. In this case, if a match does not exist, then the data source would be broken. GIS services are automated geographic information services that are This is not required when using Oracle. A layer will not display when zoomed in beyond the maximum scale. Returns True if a layer is a feature layer. Enter a plus or minus sign to the left of the value to specify whether it is above or below 0. to only the rows that match the where clause. Not all layer types support time properties. For example, a feature layer supports a definition query, whereas a raster layer does not, but a raster catalog does. If the result of the SQL query entered returns a spatial column, the output will be a feature layer. This script simply defines the connection information, then exports the map document to a PDF file. Use a regular feature layer and set its definition query using Layer object using arcpy. For enterprise geodatabase layers, a string containing the layer's connection information is returned. The same applies if a group layer is within another group layer. protocols. A string that includes the location and name of the output layer file (.lyrx). Rasterization of vector layers during output most often occurs when layer transparency is used but can also happen when a layer has raster-based picture symbols or field-based transparency. Provides the ability to either get or set the layer's credits or copyright information. Returns True if a layer is a GIS service layer. A modified CIM definition object originally retrieved using getDefinition. Structured Query Language (SQL) is a powerful language used to define one or more criteria that can consist of attributes, operators, and calculations. ArcGIS Pro can read legacy .lyr file types, but it can only save to .lyrx file types. The default, neutral contrast, is 0 percent. Enter any value between +100% and -100%. If the value returned is not OTHER, then the layer's symbology property will return one of the following symbology classes, each with their own unique set of methods and properties: GraduatedColorsSymbology, GraduatedSymbolsSymbology, RasterClassifiedSymbology, and UniqueValuesSymbology. There are numerous types of layers, and not all of them support the same set of properties. A string that specifies the extrusion method. For example, a layer named Layer1 in a group layer named Group1 will have a longNamevalue of Group1\Layer1. If the service is not password protected, this property will be null. Sample Viewer View Sample on GitHub. A layer's maximum scale threshold for 2D maps and its maximum distance above ground for 3D maps. query now supports true curves in an input geometry parameter. The feature is extruded to the specified z-value, as a flat top, regardless of the z-values of the feature. Boolean properties don't need to be tested using supports because if a layer property isn't supported for that layer type, a False value gets returned. Not all layers support the brightness property (for example, group layers and feature layers), so it is good practice to test for this ahead of time using the supports method. A wildcard is based on the label class name and is not case sensitive. There is currently no option to create or alter query layers through Python at 9.x or 10. The following script will allow secured layers to render correctly by creating an SDE connection in memory before opening a map document that requires password information. If you have access to the Beta program you can take a look at the "Make Query Layer" tool in 10.1 Beta. To clear the selection, use the NEW selection method with an empty set. This code sample is available for these platforms: WPF UWP FORMS IOS ANDROID. 2. Returns the complete path for the layer's data source. Not all layers support the workspacePath property (for example, web services), so it is good practice to test for this ahead of time using the supports method. The layer definition is a subset of the webmap_json used in the ConvertWebMapToArcGISProject function. Spaces can be included. If the input is a feature class or dataset path, this tool will automatically create and return a new layer with the result of the tool applied. ArcGIS API for JavaScript and ArcGIS Web AppBuilder allow you to get this JSON string from the web app. Returns a path to the layer's workspace or connection file. If the SQL query does not return a spatial column, the output will be a stand-alone table. protocols. Replaces a data source for a layer in a map document (.mxd) or layer (.lyr) file. Returns a layer's selection as a Python set of object IDs. The ArcGIS Web APIs (JavaScript, Flex, and The support method gives you the option of testing the property before trying to get or set its value on a layer type that doesn't support it. It then uses time information (start time and end time) to calculate the time extent of a time-enabled layer. A string keyword that represents the workspace type of the new data. If a layer does not belong to a group layer, the long name will equal the layer name. Not all layers support the same set of properties; the supports property can be used to test if a layer supports that property before attempting to set it. If set to False, the method will set all connections to match the new_connection_info, regardless of a valid match. Used to determine if a particular layer type supports a property on the layer object. Returns the name of the layer's dataset the way it appears in the workspace, not in the TOC. Provides an easy way to retrieve the layer's current selection. Returns a string that represents the layer's symbology class type. Provides access to a layer's label class properties by returning a list of LabelClass objects. ServiceType —The property displaying the type of service. 2 réponses; Tri: Actif. Not all layers support the serviceProperties property (for example, layers that are not ArcSDE or web service layers), so it is good practice to test for this ahead of time using the supports method. The layer definition is a subset of the webmap_json used in the ConvertWebMapToMapDocument If set to True, labels will display; if set to False, labels will not be drawn. The web services dictionary contains keys that work for all service layer types and also includes specific keys that work for only a particular web service type (for example, WMS has a key called WMSTitle). Map documents that contain these layers will prompt the user to enter the appropriate information while the document is opening. Enter any value between +100% and -100%. The da cursors require you to list the fields you want to work with. Saves a layer (.lyr) file to a different file name and, optionally, a previous version. Depending on the symbology type, a layer's symbology can be modified. To clear the selection, use the NEW selection method with an empty list or don't set any parameters. However, you need to extract the layer definition from the full webmap_json. If set to True, labels will display; if set to False, labels will not be drawn. If the SQL query does not return … It is good practice to delete this reference from memory before the script closes. Second, you can evaluate the longName property. Esri follows the semantic versioning specification. Group layers and other sublayers (for example, annotation classes) are treated just like ordinary layers. A layer's minimum threshold to display the features. It includes the full workspace path and name of the dataset. Créé 07 mars. This provides a method to create three-dimensional symbology from two-dimensional features. The name of a layer the way it would appear in the table of contents. A wildcard is based on the layer name and is not case sensitive. Query layers will only work with enterprise databases. It first updates the layer's symbology using a layer file on disk with the UpdateLayer function. There are numerous types of layers and not all of them support the same properties. import arcpy. for you. An important property of Layer objects is the ability to dynamically set definition queries. Provides an easy way to retrieve the layer's current selection. A string that defines the extrusion expression, which provides an absolute extrusion height for each feature. This will only be SDE for ArcSDE layer types. Returns True if a layer is a GIS service layer. To clear the minimum scale, set the value to 0. ACCESS_WORKSPACE — A personal geodatabase or Access workspace, ARCINFO_WORKSPACE — An ArcInfo coverage workspace, FILEGDB_WORKSPACE —A file geodatabase workspace, OLEDB_WORKSPACE —An OLE database workspace, PCCOVERAGE_WORKSPACE —A PC ARC/INFO Coverage workspace, SDE_WORKSPACE —An SDE geodatabase workspace, SHAPEFILE_WORKSPACE —A shapefile workspace, NEW —Creates a new feature selection from the, DIFFERENCE —Selects the features that are not in the current selection but are in the, INTERSECT —Selects the features that are in the current selection and the, SYMDIFFERENCE —Selects the features that are in the current selection or the, UNION —Selects all the features in both the current selection and those in the, BRIGHTNESS —A raster layer's brightness value, CONTRAST —A raster layer's contrast value, DATASETNAME —A layers dataset name the way it appears in the workspace, DATASOURCE —A layer's file path or connection file, DEFINITIONQUERY —A layer's definition query string, DESCRIPTION —A layer's description string, LABELCLASSES —A layer's list of label classes, LONGNAME —A layer's path including the group layer(s) it may be nested within, SERVICEPROPERTIES —Connection information for SDE and web service layers, SHOWLABELS —A Boolean indicating if a layer's lables are toggled on or off, SYMBOLOGYTYPE —A layer's symbology class type, TRANSPARENCY —A layer's transparency value, VISIBLE —A Boolean indicating if a layer is toggled on or off in the TOC, WORKSPACEPATH —A layer's workspace or connection file path.
