Strymmap Example

Apart from CAN bus data, comma.ai’s grey panda and black panda devices also record GPS data. strymmap enables to read the GPS data from such recording and make interesting observation.

import strym
from strym import strymmap
import matplotlib.pyplot as plt
import pandas as pd

datafolder='../../PandaData/2020_03_12/'
file = '2020-03-12-10-56-10_GPS_Messages.csv'
g = strymmap(csvfile=datafolder+file)
g.dataframe = g.dataframe.dropna()

GPS signal first acquired at 2020-03-12 17:56:20:600000

Looking for [chromedriver 85.0.4183.87 linux64] driver in cache
File found in cache by path [/home/ivory/.wdm/drivers/chromedriver/85.0.4183.87/linux64/chromedriver]

fig = g.plotroute(interactive=False)

We can create such maps for all drive for which we have GPS recording

import glob
parentfolder = '../../PandaData/'
folderlist = glob.glob(parentfolder+"*")
csvlist = []
for datafolder in folderlist:
    csvlisttmp = glob.glob(datafolder+"/*.csv")
    for f in csvlisttmp:
        csvlist.append(f)

for index, f in enumerate(csvlist):
    if 'GPS' in f:
        print('{}. File currently being read is {}'.format(index, f))
        g = strymmap(csvfile=f)
        try:
            g.dataframe = g.dataframe.dropna()
        except AttributeError:
            pass
        print('\n')
