Python wrapper for the MEOS C Library.
Project description
MEOS (Mobility Engine, Open Source) is a C library which enables the manipulation of
temporal and spatio-temporal data based on MobilityDB's data types and functions.
PyMEOS is a Python library built on top of MEOS using CFFI which presents a set of classes to manipulate spatio-temporal
information
Usage
Installation
pip install pymeos
:warning: PyMEOS wheel should be compatible with any system, but it is possible that the pre-built distribution is not available for PyMEOS CFFI for some OS/Architecture.
If it is not available, see the source installation notes on PyMEOS CFFI's readme on how to proceed
Sample code
:warning: IMPORTANT Before using any PyMEOS function, always call
meos_initialize
. Otherwise, the library will crash with aSegmentation Fault
error. You should also always callmeos_finish
at the end of your code.
from pymeos import meos_initialize, meos_finish, TGeogPointInst, TGeogPointSeq
# Important: Always initialize MEOS library
meos_initialize()
sequence_from_string = TGeogPointSeq(string='[Point(10.0 10.0)@2019-09-01 00:00:00+01, Point(20.0 20.0)@2019-09-02 00:00:00+01, Point(10.0 10.0)@2019-09-03 00:00:00+01]')
print(f'Output: {sequence_from_string}')
sequence_from_points = TGeogPointSeq(instant_list=[TGeogPointInst(string='Point(10.0 10.0)@2019-09-01 00:00:00+01'), TGeogPointInst(string='Point(20.0 20.0)@2019-09-02 00:00:00+01'), TGeogPointInst(string='Point(10.0 10.0)@2019-09-03 00:00:00+01')], lower_inc=True, upper_inc=True)
speed = sequence_from_points.speed
print(f'Speeds: {speed}')
# Call finish at the end of your code
meos_finish()
