Type a plus or minus sign to the left of the value to specify whether it is above or below 0. Provides the ability to get or set a layer's definition query. AuthenticationMode —Geodatabase or operating system authentication. Returns True if a layer is a raster layer. Sets a layer's selection using a Python set of object IDs. If the connection to ArcGIS for Server is through the Internet (HTTP), this value will be null. Changing a layer's data source is a common requirement. Query expressions can be used in ArcGIS to select a subset of features from a feature table. The name of a particular layer property that will be tested. There are numerous types of layers and not all of them support the same properties. There are essentially three categories of layers in a map document: feature layers, group layers, and raster layers. The default, normal brightness, is 0%. query now supports true curves in an input geometry parameter. the ExportWebMap JSON specification for more Selects the features that are not in the current selection but are in the, Selects the features that are in the current selection and the, Selects the features that are in the current selection or the, Selects all the features in both the current selection and those in the. The following script will print the name of each SDE or web service layer along with the appropriate service information. Returns a string that represents the layer's symbology class type. limit the resulting list. Controls the display of labels for a layer. information. The query can be used to join several tables or return a subset of fields or rows from the original data in the database. A layer's longName value will include the group name in addition to the layer name. Silverlight) allow developers to easily get this JSON string from 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. arcpy query-layer 189 . Not all layers support the same set of properties. See There are a few specialized layers and datasets that don't fall into one of these general categories: annotation subclasses, dimension features, terrain datasets, topology datasets, and so on. For more detailed discussion, parameter information, scenarios, and code samples, please refer to the Updating and fixing data sources with arcpy.mapping help topic. It also provides the ability to switch workspace types (e.g., replaces a file geodatabase data source with an SDE 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. Returns True if a layer is a group layer. Returns True if a layer is a GIS service layer. Enterprise geodatabase layers in an ArcGIS Pro project do not retain the path to the database connection file (.sde) that was used to create the layer. A value of 0 is not transparent. Provides the ability to get or set the brightness value. Thanks,-Cory a web application. This enables you to see through a layer. In this page, we are going to observe how the following can be accomplished: Import libraries Server —The name or IP address of the computer where the ArcSDE geodatabase is located. This method provides an easy way to manage a layer's selection. For example, a layer named Layer1 in a group layer named Group1 will have a longNamevalue of Group1\Layer1. Not all layer properties are accessible through the Layer object. 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. First, you can check to see if the layer supports the isGroupLayer property. For enterprise geodatabase layers, a string containing the layer's connection information is returned. Type a plus or minus sign to the left of the value to specify whether it is above or below 0. Note: Python Lists are used for setting the oidList but Python Sets get returned from the getSelectionSet method on the Layer object. This is most useful in large or complicated data sets. Returns True if a layer is a feature layer. The listLayers method on the Map Class 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 file. If a value of OTHER is returned, then the layer's symbology can't be modified. For more detailed discussion, parameter information, scenarios, and code samples, refer to the Updating and fixing data sources help topic. The default, neutral contrast, is 0 percent. GIS services are automated geographic information services that are An important property of Layer objects is the ability to dynamically set definition queries. Le plus ancien. gdb" # Make a layer from the feature class arcpy. Returns True if a layer is a raster layer. If a group layer is being saved, all of the layers below it in the TOC will also be saved to the layer file (.lyrx). The default value will use the current version. Returns True if a layer is a scene layer. Enter any value between +100 percent and -100 percent. feature_layer. A layer's maximum threshold to display the features. Currently, there is no alternative for secured web services. If set to True, the updateConnectionProperties method will also update the connections for associated joins or relates. A layer's longName value will include the group name in addition to the layer name. A string that represents the workspace path or connection file you want to replace. Controls the display of a layer. There is a method and a property on the Layer object that help with this. Returns a path to the layer's workspace or connection file. 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. The Layerobject is essential for managing layers that reside within a map document (.mxd) or within a layer (.lyr) file. The same applies if a group layer is within another group layer. Saves a layer (.lyr) file to a different file name and, optionally, a previous version. CIM-level access to additional object properties was introduced at version 2.4. Replaces connection properties using a dictionary or a path to a workspace. Provides an option to save a layer (.lyr) file to a different file name and, optionally, a previous version. A wildcard is based on the label class name and is not case sensitive. Returns True if a layer's data source is broken. A string that specifies the extrusion method. Querying features using a different spatial reference ¶ In [26]: query_result1. The layer definition in JavaScript Object Notation (JSON) format. A definition query is a SQL statement where clause that limits the data available for display, query, or other data operations (buffers, intersections, etc.) Provides access to layer properties and methods. To clear the maximum scale, set the value to 0. The following script clears all layer definition queries and turns off labels for all layers in a map named Yosemite National Park. If you have access to the Beta program you can take a look at the "Make Query Layer" tool in 10.1 Beta. Find features in a feature table which match an SQL query. Property displays the text string for the WMS layer used for machine-to-machine communication. Out[26]: {'wkid': 102100, 'latestWkid': 3857} By default, the query results are in the same spatial reference as the source layer. A symbolized extent takes into account the area of the feature's symbol when building the extent rectangle. String: Exemple de code. It can either reference layers in a map document (.mxd) or layers in a layer (.lyr) file. Returns: number of objects in select() query. If the layer does support time, then time properties can be accessed from the LayerTime class. Property displays the name of the IMS service. import arcpy, os arcpy.env.overwriteOutput = True grab = arcpy.GetParameterAsText(0)prep_list = grab.split(";" Features that are not supported in prior versions of the software will be removed from the newly saved layer. Adds extrusion height to the minimum z-value of the feature, and the feature is extruded to a flat top at that value. 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). This enables you to see through a layer to the layers underneath. Not all layer types support time properties. Returning a symbolized extent may be best for cartographic results because symbols won't be cut off at the data frame's edges. A transparency value of more than 90 percent usually results in the layer not being drawn at all. Feature layers define the spatial reference, geometry type (points, lines or polygons), attribute fields, and the permission settings for the data. 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. A string keyword that represents the workspace type of the new data. To do this in arcpy: arcpy.MakeFeatureLayer(, , ) Then run your cursor on (you can also just drop your directly into the search cursor). When working with the sublayers of composite layers, the longName property will contain both the sublayer and top level layer name. By default, queries are case sensitive. There are many is properties that allow you to determine if a layer fits into a general category: is3DLayer, isFeatureLayer, isGroupLayer, isRasterLayer, and isServiceLayer. A combination of asterisks (*) and characters can be used to help Setting metadata is dependent on the isReadOnly property value. The supports property will return a True if a layer supports that property. The layer that is created by the tool is temporary and will not persist after the session ends unless the project is saved or the data is persisted by making a copy using Copy Rows or Copy Features. Determines whether searches will be case sensitive or not. If this function is executed prior to opening a map document (.mxd) with the MapDocument function or a layer file with the Layer function, then SDE layers will render. Provides access to basic layer properties and methods. Layer types that support the showLabels property also support the labelClasses property. Esri follows the semantic versioning specification. Query layers will only work with enterprise databases. It is best to first determine the layer's symbologyType before attempting to modify the symbology class properties. Créé 07 mars.
