Exemple de code
Create a polyline feature class from scratch.
import arcpy # A list of features and coordinate pairs # coordList = [[[1,2], [2,4], [3,7]], [[6,8], [5,7], [7,2], [9,5]]] # Create empty Point and Array objects # point = arcpy.Point() array = arcpy.Array() # A list that will hold each of the Polyline objects # featureList = [] for feature in coordList: # For each coordinate pair, set the x,y properties and add to the # Array object. # for coordPair in feature: point.X = coordPair[0] point.Y = coordPair[1] array.add(point) # Create a Polyline object based on the array of points # polyline = arcpy.Polyline(array) # Clear the array for future use # array.removeAll() # Append to the list of Polyline objects # featureList.append(polyline) # Create a copy of the Polyline objects, by using featureList as input to # the CopyFeatures tool. # arcpy.CopyFeatures_management(featureList, "c:/geometry/polylines.shp")
