shapely

I am using Python3.4 on Mac OSX and I am trying to import shapely. I am however unable to do so. Here is my traceback: from shapely.geometry import Point File "/Users/tc9/Library/Python/3.4/lib/python/site-packages/shapely/geometry/__init__.py", line 4, in <module> from .base import CAP_STYLE, JOIN_STYLE File "/Users/tc9/Library/Python/3.4/lib/python/site-packages/shapely/geometry/base.py", line 9, in <module> from shapely.coords import CoordinateSequence File "/Users/tc9/Library/Python/3.4/lib/python/site-packages/shapely/coords.py", line 8, in <module> from shapely.geos import lgeos File "

I am using Python 3.5 64 bit in Windows 7 64 bit, shapely version 1.5.13. I have the following code that returned me a self-intersecting polygon: import numpy as np from shapely.geometry import Polygon, MultiPolygon import matplotlib.pyplot as plt x = np.array([ 0.38517325, 0.40859912, 0.43296919, 0.4583215 , 0.4583215 , 0.43296919, 0.40859912, 0.38517325, 0.36265506, 0.34100929]) y = np.array([ 62.5 , 56.17977528, 39.39698492, 0. , 0. , 17.34605377, 39.13341671, 60.4180932 , 76.02574417, 85.47008547]) polygon = Polygon(np.c_[x, y]) plt.plot(*polygon.exterior.xy) This is correct. Then I tried

I'm trying to build a GeoJSON object . My input is a csv with an address column, a lat column, and a lon column. I then created Shapely points out of the coordinates , buffer them out by a given radius, and get the dictionary of coordinates via the mapping option- so far, so good. Then, after referring to this question , I wrote the following function to get a Series of dictionaries: def make_geojson(row): return {'geometry':row['geom'], 'properties':{'address':row['address']}} and I applied it thusly: data['new_output'] = data.apply(make_geojson, axis=1) My resulting column is full of these:

What is the surveyed perimeter/area ratio of these patches of animal habitat? Which properties in this

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 Shapely-1.5.17.tar.gz Complete output from command python setup.py egg_info: Traceback (most recent call last): File "<string>", line 1, in <module> File "C:\Users\AppData\Local\Temp\pip-build-mwuxcain\Shapely\setup.py", line 38, in <module> from shapely._buildcfg import geos_version_string, geos_version, \ File "C:\Users\AppData\Local\Temp\pip-build-mwuxcain\Shapely\shapely\_buildcfg.py", line 200, in

When trying to install Shapely on my Windows 64bit computer, I cannot get the GEOS library to work. So far, I have run the OSGeo4W installer from which I installed GDAL (I believe the geos library is included in that package). After that, I checked and I have geos_c.dll on my C:\OSGeo4W\bin directory, but either I have missed some configuration steps or the library does not work. I need Shapely to work, so I also ran pip install shapely after installing GDAL, and it apparently worked (although it could not find the C library for GEOS). In my code, I can import Shapely, but when I try to use it
