How are polylines and polygons used in a map?
* In this tutorial, we add polylines and polygons to represent routes and areas on the map. // Add polylines to the map. // Polylines are useful to show a route or some other connection between points. // Store a data object with the polyline, used here to indicate an arbitrary type. // Style the polyline.

How to create centerlines from polygon features in ArcMap?
When working with polygon features, such as streets or rivers, it may be necessary to create a centerline representing the flow of the traffic along the center of a linear geographic feature. The instructions provided describe how to create centerlines from polygon features in ArcMap.
What’s the best way to draw polygons in Python?
First loads faster, second draws faster, if you put DISPLAYSURF.fill and than pygame.draw.polygon with a bit different coordinates into loop, it will work better than the same thing in tkinter. So if your polygon is flying and bouncing around, use second, but if it’s just stable thing, use first.
How to calculate the centerline of a polygon in Python?
There are two Python scripts. The first one, centerline.py handles the basic computations and can be used as a stand-alone script. The second one, shp2centerline.py has a more specific nature. The input is a Shapefile that contains polygons. It takes each polygon and calculates its centerline by calling the centerline.py.
Is there a polygon to centerline tool for ArcGIS Pro?
ArcGIS Pro now has a Polygon to Centerline tool, available if you have the Production Mapping extension with a standard or advanced license. Thanks for contributing an answer to Geographic Information Systems Stack Exchange! Please be sure to answer the question.
How do you remove lines from a polygon?
Remove the lines enclosing the polyline layer. Start an edit session. Select a line. Use the Split tool, if necessary, and split the line so the particular line is detached from other lines. Select the line segment, and delete.
