尝试在UBUNTU虚拟机中安装gdal2.1时,这将是我的命令行序列.我的虚拟机是UBUNTU 16.04 LTS(64位)我需要gdal2.1,特别是Python绑定在python中使用它.当前安装的python版本是2.7.11+,我安装了numpy,因为我知道GDAL是必要的.现在的命令行了
我在GDAL2.1的Pypi页面中找到的说明:
antonio19812@antonio19812-VirtualBox:~$ sudo apt-get install libgdal1i
libgdal1i is already the newest version (1.11.3+dfsg-3build2).
antonio19812@antonio19812-VirtualBox:~$ sudo apt-get install libgdal1-dev
libgdal1-dev is already the newest version (1.11.3+dfsg-3build2).
antonio19812@antonio19812-VirtualBox:~$ sudo pip install gdal

我想要list1中每个点的近似位置.所以我想指出一点list1,试着寻找最近的点,list2然后选择那个地方.我重申每一点list1.它还需要距离(以米为单位)和点的索引(in list1),因此我可以围绕它构建一些业务规则 - 基本上这些是应该添加到list1(near_dist,indx)的2个新cols .
我正在使用该gdist功能,但我无法使用它来处理数据帧输入.
示例输入列表:
