Then passed the csv and extracted the list of variables via a pandas dataframe. To be honest I originally had this functioning the exact same nested in a class, and instead of a list I saved variables in a csv. Target_val = Įxtract_cursor(fcs_in, target_field, target_val, fname) ('path/to/zachs_arc_scripts')įrom zachs_geo_script import extract_cursor

Then I run the function as such (pretend it's housed here: 'path/to/zachs_arc_scripts/zachs_geo_script.py') Shapes_union = shapes_union.union(row)Īrcpy.CopyFeatures_management(shapes_union, fname) # all features/rows matching selection criteria # merge new geometry objects to build one containing # get geometry object - Polyline in my case With arcpy.da.SearchCursor(fcs, [target_field, as cursor: Yesterday I created a function that basically does this:ĭef extract_cursor(fcs_list, target_field_list, target_val_list, fname): I want to operate using the 'in_memory' workspace OR (situation-dependent) use `arcpy.da.SearchCursor.` to access rows and return objects, perform geoprocessing tasks like merge, union, append, etc. If unchecked, all features in both the input layer and the overlay layer will be overlaid, even if they are outside the current map extent.I am developing (slowly) workflows to script geoprocessing tasks using Python and Arcpy (along with the other common suspects - pandas, numpy, etc.). If Use current map extent is checked, only the features in the input and overlay layer that are visible within the current map extent will be overlaid. All of the attributes from the input and overlay layer will be carried over to the result layer. The type of result features will depend on the overlay method and inputs. The features or portions of features in the input layer that do not overlap with the areas in the overlay layer. The input and overlay areas are combined. The dimension of the output geometry type must be the same or less than both the input and overlay dimensions, where Points=0 dimensions, Lines=1 dimension, and Areas=2 dimensions. You can specify the type of output as Points, Lines, or Areas when intersecting line or area features. The features or portions of features in the input that are overlapped with the overlay features are kept.

The Overlay Layers tool combines two layers into a single layer using one of three methods: Intersect, Union, or Erase. New Map Viewer (formerly known as Map Viewer Beta). It will be available in a future release of the This functionality is currently only supported in Map Viewer Classic (formerly known as Map Viewer).
