geopandas

On centos 7.3 minimal trying to install shapely or geopandas requires access to https://github.com/libgeos/libgeos libgeos. Trying to install this via sudo yum install libgeos-dev tells me that this package is not available. It seems that I am lacking a repository. So far I have been unable to find a working one as http://trac.osgeo.org/geos is pointing to https://yum.postgresql.org/repopackages.php#pg96 for the RPM but still after rpm -Uvh https://download.postgresql.org/pub/repos/yum/9.6/redhat/rhel-7-x86_64/pgdg-centos96-9.6-3.noarch.rpm the installation candidate is not found. It seems

When my Python application frozen with PyInstaller attempts to import Geopandas, it stops working. Windows 10 PyInstaller 3.3.1 Geopandas 0.4 Here is the source code: print("Hello, StackOverflow") import geopandas as gpd Here is the resulting console output of the compiled EXE: Hello, StackOverflow Traceback (most recent call last): File "application.py", line 3, in <module> File "<frozen importlib._bootstrap>", line 971, in _find_and_load File "<frozen importlib._bootstrap>", line 955, in _find_and_load_unlocked File "<frozen importlib._bootstrap>", line 665, in _load_unlocked File "d:

Is it possible to get counts of intersections between two geometries using GeoPandas objects? That is, I want to count up the number of polygons or line strings in one GeoDataFrame that intersect with each polygon in another GeoDataFrame. I did not see an easy way of doing this while browsing the GeoPandas docs, but wanted to check before moving on to lower-level tools. You want a spatial join: geopandas.tools.sjoin() . There's an example in this Jupyter Notebook — look at the section called Spatial join . This is counting a set of points ( midpoints ) into a set of polygons ( bins ). Both

I'm trying to make a choropleth map from polygons in a Geopandas GeoDataFrame. I want to symbolize the polygons by quantiles of a value in one of the GeoDataFrame columns. I'm trying to figure out different options and see what best fits my needs. Any advice on this would be greatly appreciated. It appears that Geopandas does have some ability to do this already: http://nbviewer.ipython.org/github/geopandas/geopandas/blob/master/examples/choropleths.ipynb tracts.plot(column='CRIME', scheme='QUANTILES', k=3, colormap='OrRd') This works, although I can't find much documentation. I'd like to be

This is in continuation with my earlier question Geospatial Analytics in Python I started a new question to keep the 2 issues logically separate. I have trying to install geopandas on python 2.6 surprisingly, geopandas is already installed by GeoSeries doesn't work and it needs a package "Fiona". I followed the instruction provided here I installed the libraries required by searching and following the suggestions (including dev libraries thinking I'll get the .h files), I am however stuck with these two issues: https://github.com/Toblerity/Fiona after cloning from git and python setup.py

GeoPandas是基于Pandas的扩展，增加了地理空间几何对象的处理，本文翻译来自于 http://www.cnblogs.com/giserliu/p/4988615.html 。原文和工程在 http://geopandas.org/ 。 GeoPandas官方中文文档--译著 译自 GeoPandas 0.1.0 文档 （原版译著，有错误欢迎交流，转载请注明） 　　GeoPandas是一个开源项目，它的目的是使得在Python下更方便的处理地理空间数据。GeoPandas扩展了pandas的数据类型，允许其在几何类型上进行空间操作。几何操作由 shapely 执行。 GeoPandas进一步依赖于 fiona 进行文件存取和 descartes ， matplotlib 进行绘图。 描述 GeoPandas 的目的是在Python下更容易处理地理数据。它结合了pandas和shaply的功能，提供在pandas下的空间操作和shapel下高层次的处理 多几何构型的接口。GeoPandas 允许你很容易的用Python进行操作，不然的话，你将不得不用一个空间数据库去处理，如PostGIS。 安装 笔者目前的发现版本是0.1，安装，可以使用pip或easy_install： pip install geopandas 你也可以通过克隆 GitHub
