The point, line or polygon features with the merge_layer. I want to join them together into a single layer, keeping only the fields that have the same name and type on the two layers. I have two layers containing parcel information for contiguous townships. I have three layers for England, Wales, and Scotland and I want a single layer of Great Britain. You can control how the fields from the input layers are joined and copied. The layers to be merged must all contain the same feature types (points, lines, or polygons). The merge_layers method copies features from two layers into a new layer. merge_layers ( input_layer, merge_layer, merging_attributes =, output_name = None, context = None, gis = None, estimate = False, future = False ) ¶ If FileGeodatase is specified and the input layer has attachments: A keyword defining the output data format for your extracted data.Ĭhoice list: By default, features are not clipped and all features intersecting the extent are returned. A Boolean value that specifies whether the features within the input layer are clipped ![]() If not specified, all features from each input layer are extracted. The extent is the area of interest used to extract the input features. The extracted data format can be a file geodatabase, shapefiles, csv, or kml.įile geodatabases and shapefiles are added to a zip file that can be downloaded. The extract_data method is used to extract data from one or more layers within a given extent. extract_data ( input_layers, extent = None, clip = False, data_format = None, output_name = None, gis = None, estimate = False, future = False ) ¶ Call result() to get the response.Įxtract_data ¶ _data. If future = True, then the result is a Future object. Result_layer : FeatureLayer if output_name is specified, else Feature Collection. The default is False, which means wait for results. If True, a future object will be returned and the process Instead of creating multipart features, individual features will be created for each part. True: Specifies multipart features are allowed.įalse: Specifies multipart features are not allowed. Share a common attribute table but are not visibly connected) are allowed in Specifies whether multipart features (i.e. If True, the number of credits to run the operation will be returned. If not specified, the active GIS is used. Optional, the GIS on which this tool runs. Layer of state boundaries with total population. Stddev - Finds the standard deviation of all the points in each polygon.įor example, if you are dissolving counties based on State_Name, and eachĬounty has a Population field, you can sum the Population for all theĬounties sharing the same State_Name attribute. ![]() Max - Finds the largest value of all the points in each polygon. Min - Finds the smallest value of all the points in each polygon. Mean - Calculates the average of all the points in each polygon. Sum - Adds the total value of all the points in each polygon Wish to calculate from the polygons that are dissolved together:įieldName is the name of one of the numeric fields found in the State boundaries.If two or more fields are specified, the values in these fields must be the same for the boundary to be dissolved.Ī list of field names and statistical summary types that you For example, if you have a layer of counties,Īnd each county has a State_Name attribute, you can dissolve boundaries using the State_Name attribute.Īdjacent counties will be merged together if they have the same value for State_Name. If you do supply values for the dissolve_fields parameter, polygons that share a common borderĪnd contain the same value in one or more fields will be dissolved. That share a common border (that is, they are adjacent) or polygon areas that overlap will be dissolved into one polygon. If you don’t supply dissolve_fields, or you supply an empty list of fields, polygons One or more fields on the input_layer that control which polygonsĪre merged. The layer containing polygon features that will be dissolved. The end result is a layer of state boundaries. If they have the same value for State_Name. Adjacent counties will be merged together ![]() Has a State_Name attribute, you can dissolve boundaries using the State_Name attribute. For example, if you have a layer of counties, and each county ![]() You can control which boundaries are merged by specifying a field. The dissolve_boundaries method finds polygons that overlap or share a common boundary and merges them together to form a single polygon. dissolve_boundaries ( input_layer, dissolve_fields =, summary_fields =, output_name = None, context = None, gis = None, estimate = False, multi_part_features = True, future = False ) ¶
