Question

我正在尝试将~4k gps点转换为折线。我最终想要缓冲点并识别路径覆盖。我得到的是一条不完整的线。有重复的点和重叠点，但我用这个数据集测试了下面的代码，它似乎运行fin

feature_info = [[[1, 2], [2, 4], [3, 7],[3, 7],[3, 7],[3, 7],[3, 7],[3, 7], [2, 4], [7, 2], [9, 5],[.5,0]]]

Points and polyline to connect points 当前代码

coordArray = arcpy.Array()
feature_info = []
newcoord = []
# Open a searchcursor
Input = '.../5PT175.shp'
rows = arcpy.SearchCursor(Input,  fields="Latitude; Longitude;Timestamp;Speed", sort_fields="Timestamp A")

# Iterate through the rows in the cursor and print out the
# state name, county and population of each.
for row in rows:
    position = [row.getValue("Longitude"),row.getValue("Latitude")]
    newcoord.append(position)
    coordArray.add(arcpy.Point(latitude,longitude))
newcoord = [newcoord]

# A list that will hold each of the Polyline objects
features = []

for feature in newcoord:
    # Create a Polyline object based on the array of points
    # Append to the list of Polyline objects
    features.append(
        arcpy.Polyline(
            arcpy.Array([arcpy.Point(*coords) for coords in feature])))

# Persist a copy of the Polyline objects using CopyFeatures
output = '.../polylines.shp'
arcpy.CopyFeatures_management(features, output)

我很乐意发布点文件，但我不确定如何在这个网站上发布。这是测试代码的片段

瑞克，

您是否尝试过Points to Line ESRI工具？
