Geospotikal
1. Latarbelakang
Perkembangan zaman menuntut kita untuk selalu update dalam pekerjaan kita sehari-hari. Disini mahasiswa/i dituntut untuk mengetahui dan mempraktekkan mengenai geospotikal dari create, update, delete dan view menggunakan bahasa python.
Dalam studi kasus kali ini saya akan menjelaskan dan mempraktekkan mengenai geospotikal dengan bahasa python melalui terminal linux.
2. Identifikasi Masalah

- Bagaimana mahasiswa/i mempraktekkan create, update, delete, dan view geospotikal melalui bahasa python?
3. Pemaparan Sekilas / praktek
4. Pemaparan
Nah kali ini kita akan menggunakan bahasa python melalui terminal dari linux. Langkah-langkahnya yaitu;
- install python-pip dan python-pyshp
- lalu download file urban_area di Natural Earth
- ekstrak filenya
- buka terminal
- ketik python dan enter
- lalu import shapefile dan enter
- ketik sf = shapefile.Reader("urban_area/ne_10m_urban_areas.shp") dan enter
- ketik shapes = sf.shapes() dan enter
- dan terakhir ketikan len(shapes) dan enter
- maka akan muncul hasil recordnya.

Installing Python Modules
| Email: | distutils-sig@python.org |
|---|
As a popular open source development project, Python has an active
supporting community of contributors and users that also make their software
available for other Python developers to use under open source license terms.
This allows Python users to share and collaborate effectively, benefiting
from the solutions others have already created to common (and sometimes
even rare!) problems, as well as potentially contributing their own
solutions to the common pool.
This guide covers the installation part of the process. For a guide to
creating and sharing your own Python projects, refer to the
distribution guide.
Note
For corporate and other institutional users, be aware that many
organisations have their own policies around using and contributing to
open source software. Please take such policies into account when making
use of the distribution and installation tools provided with Python.
Key terms
pipis the preferred installer program. Starting with Python 2.7.9, it is included by default with the Python binary installers.- a virtual environment is a semi-isolated Python environment that allows packages to be installed for use by a particular application, rather than being installed system wide
virtualenvis a third party tools for creating virtual environments, it is defaults to installingpipinto all created virtual environments.- the Python Packaging Index is a public repository of open source licensed packages made available for use by other Python users
- the Python Packaging Authority are the group of developers and documentation authors responsible for the maintenance and evolution of the standard packaging tools and the associated metadata and file format standards. They maintain a variety of tools, documentation and issue trackers on both GitHub and BitBucket.
distutilsis the original build and distribution system first added to the Python standard library in 1998. While direct use ofdistutilsis being phased out, it still laid the foundation for the current packaging and distribution infrastructure, and it not only remains part of the standard library, but its name lives on in other ways (such as the name of the mailing list used to coordinate Python packaging standards development).
Basic usage
The standard packaging tools are all designed to be used from the command line.The following command will install the latest version of a module and its dependencies from the Python Packaging Index:
python -m pip install SomePackage
Note
For POSIX users (including Mac OS X and Linux users), the examples in
this guide assume the use of a virtual environment. You may install
virtualenv to provide such environments using either pip
(pip install virtualenv) or through your system package manager
(commonly called virtualenv or python-virtualenv).
For Windows users, the examples in this guide assume that the option to
adjust the system PATH environment variable was selected when installing
Python.
>, < or some other
special character which get interpreted by shell, the package name and the
version should be enclosed within double quotes:python -m pip install SomePackage==1.0.4 # specific version
python -m pip install "SomePackage>=1.0.4" # minimum version
python -m pip install --upgrade SomePackage
pip and its capabilities can be
found in the Python Packaging User Guide.How do I ...?
These are quick answers or links for some common tasks.
... install pip in versions of Python prior to Python 2.7.9?
Python only started bundling pip with Python 2.7.9. For earlier versions,
pip needs to be “bootstrapped” as described in the Python Packaging
User Guide.... install packages just for the current user?
Passing the--user option to python -m pip install will install a
package just for the current user, rather than for all users of the system.... install scientific Python packages?
A number of scientific Python packages have complex binary dependencies, and aren’t currently easy to install usingpip directly. At this point in
time, it will often be easier for users to install these packages by
other means
rather than attempting to install them with pip.... work with multiple versions of Python installed in parallel?
On Linux, Mac OS X and other POSIX systems, use the versioned Python commands in combination with the-m switch to run the appropriate copy of
pip:python2 -m pip install SomePackage # default Python 2
python2.7 -m pip install SomePackage # specifically Python 2.7
python3 -m pip install SomePackage # default Python 3
python3.4 -m pip install SomePackage # specifically Python 3.4
pip commands may also be available)On Windows, use the
py Python launcher in combination with the -m
switch:py -2 -m pip install SomePackage # default Python 2
py -2.7 -m pip install SomePackage # specifically Python 2.7
py -3 -m pip install SomePackage # default Python 3
py -3.4 -m pip install SomePackage # specifically Python 3.4
Common installation issues
Installing into the system Python on Linux
On Linux systems, a Python installation will typically be included as part of the distribution. Installing into this Python installation requires root access to the system, and may interfere with the operation of the system package manager and other components of the system if a component is unexpectedly upgraded usingpip.On such systems, it is often better to use a virtual environment or a per-user installation when installing packages with
pip.Installing binary extensions
Python has typically relied heavily on source based distribution, with end users being expected to compile extension modules from source as part of the installation process.With the introduction of support for the binary
wheel format, and the
ability to publish wheels for at least Windows and Mac OS X through the
Python Packaging Index, this problem is expected to diminish over time,
as users are more regularly able to install pre-built extensions rather
than needing to build them themselves.Some of the solutions for installing scientific software that is not yet available as pre-built
wheel files may also help with
obtaining other binary extensions without needing to build them locally.
6. Kesimpulan dan Saran
Jadi, dalam praktek ini dapat kita simpulkan bahwa dalam penggunaan bahasa pyton mungkin dalam prosesnya cepat, akan tetapi masih memakai bahasa robot. :v
