… polys.append (arcpy.Polygon (polyPoints,arcpy.SpatialReference (4326))) # create polygon and add to list Unless you’re committed to learning Python, your best bet is probably to add your csv as points, convert to line, then convert to polygon. 09-29-2015 10:31 AM
How can I use ArcGIS to create polygons?
For example, you can load a set of collected points from a global positioning system (GPS) unit into ArcGIS and use this tool to create polyline or polygon features from those points. Ideally, the points would be loaded with associated waypoint IDs that can be used to determine to which path or area the points belong and/or define draw order.
Can you convert a shapely polygon to a NumPy array?
If you really want the shapely point objects that make up the polygon, and not just tuples of coordinates, you can do that this way: You can convert a shapely Polygon to a NumPy array using NumPy.array.
How to get the first vertex of a polygon?
To get the first vertex, for example, use polygon.exterior.coords [0]. Note that the first and last points are the same; if you want a list consisting of the vertices without that repeated point, use polygon.exterior.coords [:-1]. You can convert the CoordinateSequence (including the repeated vertex) to a list of points thus:
How to stack overflow point in polygon using shapely?
– Stack Overflow Point in polygon using shapely? I am running the following script which I believe should be returning TRUE for the point being in the polygon but it is returning FALSE. Any idea why the shapely script is returning FALSE?
Can a shapefile be a polygon or multipolygon?
Shapefiles have no type MultiPolygon (type = Polygon), but they support them anyway (all rings are stored in one feature = list of polygons, look at Converting huge multipolygon to polygons)
How to check if a point is within a polygon?
Point takes longitude, then latitude in the argument. Not latitude first. You can call polygon_object.contains or polygon_object.within function to check if the point is within the shape. Thanks for contributing an answer to Geographic Information Systems Stack Exchange!
