The following script will print the name of each SDE or web service layer along with the appropriate service information. The following script prints the name of each map in a project and lists the names of the layers in each map. Returns the complete path for the layer's data source. A layer's minimum scale threshold for 2D maps and its maximum distance above ground for 3D maps. Provides the ability to get or set the brightness value. For example, a feature layer supports a definition query whereas a raster layer does not, but a raster catalog does. 2. 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. 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. If the input's data source is a feature service, it is recommended that the underlying ArcGIS Server use standardized SQL queries. Use values between 0 and 100. For more detailed discussion, parameter information, scenarios, and code samples, refer to the Updating and fixing data sources help topic. If you have access to the Beta program you can take a look at the "Make Query Layer" tool in 10.1 Beta. This code sample is available for these platforms: WPF UWP FORMS IOS ANDROID. Database —The name of the enterprise RDBMS database. The default, neutral contrast, is 0 percent. UserName —A user account. Esri basemaps are an example. Each supported layer symbology class has its own unique set of properties. Structured Query Language (SQL) is a powerful language used to define one or more criteria that can consist of attributes, operators, and calculations. If the layer does support time, then time properties can be accessed from the LayerTime class. Returns a layer's geometric or symbolized extent. Provides the ability to set or get the layer's maximum scale threshold. 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. String: Exemple de code. query now supports true curves in an input geometry parameter. If the service is not password protected, this property will be null. Title —WMS service layers only. published and accessed over the web using standard technologies and There are numerous types of layers and not all of them support the same set of properties. A layer's transparency value. ServiceType —Property displaying the type of service. If you want to create an application that can access feature layer data you can use the ArcGIS REST API and the query operation. 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. A string that sets the output version number. The layer definition is a subset of the webmap_json used in the ConvertWebMapToMapDocument In this case, if a match does not exist, then the layer's data source would be broken. UserName —Property displaying the user name used to access a secured service. ArcGIS Pro can read legacy .lyr file types, but it can only save to .lyrx file types. There are many is properties that allow you to determine if a layer fits into a general category: is3DLayer, isFeatureLayer, isGroupLayer, isRasterLayer, and isServiceLayer. Provides access to connection information for ArcSDE and web service layers. A layer will not display when zoomed in beyond the maximum scale. Setting metadata is dependent on the isReadOnly property value. For example, a feature layer supports a definition query, whereas a raster layer does not, but a raster catalog does. If it is not valid, the connection will not be replaced. A layer's path including the group layers it may be nested within. 16 2016-03-07 19:00:20 Marco_B. Enter any value between +100% and -100%. If the name value is equal to the longName value, the layer is not inside a group layer. Learn more about JSON Curve Objects in Geometry Objects. Type a plus or minus sign to the left of the value to specify whether it is above or below 0. gdb" # Make a layer from the feature class arcpy. If the SQL query does not return … The Layerobject is essential for managing layers that reside within a map document (.mxd) or within a layer (.lyr) file. 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. Saves a layer (.lyr) file to a different file name and, optionally, a previous version. A string that includes the workspace path to the new data or connection file. Returns True if a layer is a GIS service layer. 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. When working on a map with multiple query layers that reference a database table, in some cases, the query layers' SQL expression requires an update. For a more detailed discussion, parameter information, scenarios, and code samples, refer to the Updating and fixing data sources help topic. A string that represents the name of the dataset the way it appears in the new workspace (not the name of the layer in the TOC). Query layers allow both spatial and nonspatial information stored in a DBMS to be easily integrated into GIS projects within ArcMap. A layer's longName value will include the group name in addition to the layer name. Provides the ability to set or get the layer's minimum scale threshold. 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. The supports method is available to help identify which specific layer supports which specific layer property. Not all layers support the transparency property (for example, fabric group layers and web service sublayers), so it is good practice to test for this ahead of time using the supports method. Replaces a data source for a layer in a map document (.mxd) or layer (.lyr) file. There is a method and a property on the Layer object that help with this. Get or set the layer's Metadata class information. A string that specifies the extrusion method. File or personal geodatabases are not valid input workspaces for this tool. See the ExportWebMap JSON specification for more information. Not all layers support the showLabels property (for example, raster layers and annotation layers), so it is good practice to test for this ahead of time using the supports method. 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. This enables you to see through a layer. Not all layers support the datasetName property (for example, web services), so it is good practice to test for this ahead of time using the supports method. The layer file contains a custom color ramp that is applied to the layer. All layer types support this property. spatial_reference. Example one below shows how you can get the time extent of your time-enabled layer using the startTime and endTime. The layer definition is a subset of the webmap_json used in the ConvertWebMapToArcGISProject function. A Python set of object IDs to use along with the appropriate selection method. The layerobject provides access to many of the common layer properties found in the ArcMap Layer Propertiesdialog box and it also provides methods for saving layer files. There are numerous types of layers, and not all of them support the same set of properties. The first is for ArcSDE connections, and the second is for all web service layer types. Type 0 if you don't want a layer to be transparent. Use case. 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. A string that represents the major version of the CIM. Controls the display of labels for a layer. Thanks,-Cory First, you can check to see if the layer supports the isGroupLayer property. The default, neutral contrast, is 0%. lyr.brightness = 10. Can I use this tool to create a layer from a "query layer" table data source (i.e. Selecting Columns with Pandas iloc. This enables you to see through a layer to the layers underneath. Returns True if a layer is an ArcGIS Network Analyst エクステンション layer type. Not all layers support the description property (for example, topology layers), so it is good practice to test for this ahead of time using the supports method. Layer types that support the showLabels property also support the labelClasses property.
