🌍 catchments
=============

Python wrapper for multiple APIs, that provide catchments-areas.
It allows to acquire and manipulate catchments from those APIs.

Installation
------------

.. code-block:: bash

    $ pip install catchments

Usage
-----

Currently there are implemented two classes: **SkobblerAPI** and **HereAPI**.

You can use them as follows:

.. code-block:: python

    >>> from catchments import SkobblerAPI

    >>> # get catchment from Skobbler API
    >>> skobbler = SkobblerAPI('your_api_key')
    >>> # if you don't provide params values default ones will be used
    >>> params = {"range": 600, "highways": 1}
    >>> catchment = skobbler.get_catchment({"lat" 52.05, "lon": 16.82}, **params)
    >>> {"realReach": {...} ...}
    >>> geojson = skobbler.catchment_as_geojson(catchment)
    >>> {"type": "Feature", geometry: {"type": "Polygon", ...}, ...}
    >>> skobbler.save_as_geojson(geojson)
    >>> 'SKOBBLER_52.05_16.82.geojson'

As you can see **.get_catchment** method uses **params** as second argument. Params keys names should be exactly the same
as mentioned in APIs documentations, otherwise they will be ignored and default values will be used.

Params supported by SKOBBLER and HERE:

`SKOBBLER <https://developer.skobbler.com/getting-started/web#sec3>`_ (startMercator, response_type - not supported)

`HERE <https://developer.here.com/rest-apis/documentation/routing/topics/request-isoline.html>`_

You can use also inbuilt command line scripts which accept \*.csv file input with points as coordinates resource.
Scripts generate \*.geojson files for every point in given \*.csv file.

Example \*.csv file structure (name column is optional):

+------------+------------+------------+ 
|    name    |    lat     |    lon     | 
+============+============+============+ 
|   point1   |  52.0557   |  16.8278   | 
+------------+------------+------------+ 
|   point2   |  52.4639   |  16.9410   | 
+------------+------------+------------+ 

Example command line script usage:

.. code-block:: bash

    $ catchments-skobbler.py -k your_api_key -p path/to/file/with/points/*.csv

All scripts and their options are mentioned below:

.. code-block:: bash

    $ catchments-skobbler.py

* -k --key [REQUIRED] [DEFAULT: **None**]

* -p --points [REQUIRED] [DEFAULT: **None**]

* -t --transport - [OPTIONAL] [DEFAULT: **car**]

* -l --toll - [OPTIONAL] [DEFAULT: **0**]

* -w --highways - [OPTIONAL] [DEFAULT: **0**]

* -n --nonReachable - [OPTIONAL] [DEFAULT: **0**]

.. code-block:: bash

    $ catchments-here.py

* -i --app_id [REQUIRED] [DEFAULT: **None**]

* -c --app_code [REQUIRED] [DEFAULT: **None**]

* -r --range - [OPTIONAL] [DEFAULT: **600**]

* -e --range-type - [OPTIONAL] [DEFAULT: **time**]

* -m --mode - [OPTIONAL] [DEFAULT: **fastest;car;traffic:disabled**]
