I have been trying to debug this problem but unable to do so. I am trying to find the intersection of two Polygon objects. It works most of the time but for the following case, it raises the follow...

I've just installed Anaconda in my new laptop, and created an environment with geopandas installed in it. I've tried to upload the world map that comes with geopandas through the following code: im...

I'm working with shapely to do GIS, but I'm running into memory errors when loading the geometry of each zip code into memory because the geometry is so jagged and complicated. I'd like to make t...

I have a LineString defined by two points, so essentially a straight line segment, and I wanted to project a point on to it. I am aware of .project and .interpolate. However when the point is "outs...

I want to create a polygon from shapely points. from shapely import geometry p1 = geometry.Point(0,0) p2 = geometry.Point(1,0) p3 = geometry.Point(1,1) p4 = geometry.Point(0,1) pointList = [p1, p...

I'm trying to use shapley, and to use it for what I need it for, I have to import "from shapely import geometry" but I get the error OSError: Could not find lib geos_c.dll I've tried to i...

How do you triangulate a polygon in Shapely? Shapely actually offers a triangulate() function, but that only triangulates the vertices of the polygon as a point set. For convex polygons the solutio...

How do I fund the nearest LINESTRING near a point? First I have a list of LINESTRING and point value. How do I have the nearest LINESTRING to the POINT (5.41 3.9) and maybee the distance? from shap...

i have a geoJSON geo = {'type': 'Polygon', 'coordinates': [[[23.08437310100004, 53.15448536100007], [23.08459767900007, 53.15448536100007], [23.08594514600003, 53.153587050000056], (...) [23.0...

I have a geodataframe showing ~25 locations represented as point geometry. I am trying to come up with a script that goes through each point, identifies the nearest location and returns the name of...

I'm working with Shapely polygons and I need a way to delete all smaller polygons contained within a bigger polygon. I tried using the .contains() method which Shapely provides, but the method does...

I am using shapely in python and trying to generate evenly spaced points in a grid that fall within a shape in the fastest O(n) time. The shape may be any closed polygon, not just a square or circl...

I'm just trying to use the demo code. I run the following in Jupyter Notebook: from shapely.geometry import shape Which gives me the following: OSError Traceback (most recent call last) <ipyt...

Good morning all, I am trying to load a .pbf file using the pyrosm library's documentation. My code below. import pyrosm # Get filepath to test PBF dataset fp = pyrosm.get_data("wisconsin&quo...

I am using the parallel_offset function of the shapely package to get offset structures to some polygons that are closed rings. I have several polygons at once, many with similar shapes. Around 10-...

Is there a method to extract a grid of coordinates (purple dots) from a center coordinate, with a 100 meters distance between each coordinate for example? For example having an input of latitude a...

I've installed shapely with pip install shapely and importing it as from shapely.geometry import Point. I get this error: from shapely.geometry import Point ModuleNotFoundError: No module named '...

Could not find library geos_c or load any of its variants ['libgeos_c.so.1', 'libgeos_c.so'] using the python:3.5.1 image I am trying to run a container that includes among other things it install...

I am using python and I have defined the latitudes and longitudes (in degrees) of a polygon on the map. My goal is to check if a generic point P of coordinates x,y falls within such polygon. I woul...

I have a geodataframe with a Multipolygon geometry: I would like to convert them to Polygons i.e. fill in the holes of multipolygon and make it a single polygon. I have tried the code from this si...

I have a set of LineStrings which are intersected by other LineStrings and I want to split the LineString into separate segments at these intersection points. I have a solution but I don't think it...

I want to calculate the overlapped area "THE GRAY REGION" between red and blue rectangles. Each rectangle is defined by its four corner coordinates. The resulted unit of the overlapped area is ...

I have to install Shapely package (http://toblerity.org/shapely/project.html#installation). But when I am using: pip install Shapely I am getting this error: Collecting Shapely Using cached S...

How can I check if a polygon entity is actually a multipolygon? I've tried: if len(polygon) > 1: but then get the error: TypeError: object of type 'Polygon' has no len() I've tried Nill, ...

Say I have the following Polygon and Point: >>> poly = Polygon([(0, 0), (2, 8), (14, 10), (6, 1)]) >>> point = Point(12, 4) I can calculate the point's distance to the polygo...
