Description:
 def identify(self, geometry, mapExtent, imageDisplay, tolerance, geometryType="esriGeometryPoint", sr=None, layerDefs=None, time=None, layerTimeOptions=None, layers="top", returnGeometry=True, maxAllowableOffset=None, geometryPrecision=None, dynamicLayers=None, returnZ=False, returnM=False, gdbVersion=None):
 """ The identify operation is performed on a map service resource to discover features at a geographic location. The result of this operation is an identify results resource. Each identified result includes its name, layer ID, layer name, geometry and geometry type, and other attributes of that result as name-value pairs. Inputs: geometry - The geometry to identify on. The type of the geometry is specified by the geometryType parameter. The structure of the geometries is same as the structure of the JSON geometry objects returned by the ArcGIS REST API. In addition to the JSON structures, for points and envelopes, you can specify the geometries with a simpler comma-separated syntax. Syntax: JSON structures: <geometryType>&geometry={ geometry} Point simple syntax: esriGeometryPoint&geometry=<x>,<y> Envelope simple syntax: esriGeometryEnvelope&geometry=<xmin>,<ymin>,<xmax>,<ymax> geometryType - The type of geometry specified by the geometry parameter. The geometry type could be a point, line, polygon, or an envelope. Values: esriGeometryPoint | esriGeometryMultipoint | esriGeometryPolyline | esriGeometryPolygon | esriGeometryEnvelope sr - The well-known ID of the spatial reference of the input and output geometries as well as the mapExtent. If sr is not specified, the geometry and the mapExtent are assumed to be in the spatial reference of the map, and the output geometries are also in the spatial reference of the map. layerDefs - Allows you to filter the features of individual layers in the exported map by specifying definition expressions for those layers. Definition expression for a layer that is published with the service will be always honored. time - The time instant or the time extent of the features to be identified. layerTimeOptions - The time options per layer. Users can indicate whether or not the layer should use the time extent specified by the time parameter or not, whether to draw the layer features cumulatively or not and the time offsets for the layer. layers - The layers to perform the identify operation on. There are three ways to specify which layers to identify on: top: Only the top-most layer at the specified location. visible: All visible layers at the specified location. all: All layers at the specified location. tolerance - The distance in screen pixels from the specified geometry within which the identify should be performed. The value for the tolerance is an integer. mapExtent - The extent or bounding box of the map currently being viewed. Unless the sr parameter has been specified, the mapExtent is assumed to be in the spatial reference of the map. Syntax: <xmin>, <ymin>, <xmax>, <ymax> The mapExtent and the imageDisplay parameters are used by the server to determine the layers visible in the current extent. They are also used to calculate the distance on the map to search based on the tolerance in screen pixels. imageDisplay - The screen image display parameters (width, height, and DPI) of the map being currently viewed. The mapExtent and the imageDisplay parameters are used by the server to determine the layers visible in the current extent. They are also used to calculate the distance on the map to search based on the tolerance in screen pixels. Syntax: <width>, <height>, <dpi> returnGeometry - If true, the resultset will include the geometries associated with each result. The default is true. maxAllowableOffset - This option can be used to specify the maximum allowable offset to be used for generalizing geometries returned by the identify operation. The maxAllowableOffset is in the units of the sr. If sr is not specified, maxAllowableOffset is assumed to be in the unit of the spatial reference of the map. geometryPrecision - This option can be used to specify the number of decimal places in the response geometries returned by the identify operation. This applies to X and Y values only (not m or z-values). dynamicLayers - Use dynamicLayers property to reorder layers and change the layer data source. dynamicLayers can also be used to add new layer that was not defined in the map used to create the map service. The new layer should have its source pointing to one of the registered workspaces that was defined at the time the map service was created. The order of dynamicLayers array defines the layer drawing order. The first element of the dynamicLayers is stacked on top of all other layers. When defining a dynamic layer, source is required. returnZ - If true, Z values will be included in the results if the features have Z values. Otherwise, Z values are not returned. The default is false. This parameter only applies if returnGeometry=true. returnM - If true, M values will be included in the results if the features have M values. Otherwise, M values are not returned. The default is false. This parameter only applies if returnGeometry=true. gdbVersion - Switch map layers to point to an alternate geodatabase version. """
