Usage/Examples

from SICAR import Sicar, State, Polygon

state_dates = car.get_release_dates()
pprint.pprint(state_dates)

# Download APPS polygon for the PA state
car.download_state(State.PA, Polygon.APPS)

OCR drivers

Optical character recognition (OCR) drivers are used to recognize characters in a captcha.

We currently have two options for automating the download process.

Tesseract OCR (Default)

from SICAR import Sicar, State, Polygon
from SICAR.drivers import Tesseract

# Create Sicar instance using Tesseract OCR
car = Sicar(driver=Tesseract)

# Download a state
car.download_state(State.SP, Polygon.LEGAL_RESERVE, folder='SICAR/SP')

PaddleOCR

Install SICAR with pip and include Paddle dependencies

pip install 'SICAR[paddle] @  git+https://github.com/urbanogilson/SICAR'

from SICAR import Sicar, State, Polygon
from SICAR.drivers import Paddle

# Create Sicar instance using PaddleOCR
car = Sicar(driver=Paddle)

# Download a state
car.download_state(State.AM, Polygon.CONSOLIDATED_AREA, folder='SICAR/AM')

Run with Google Colab

Using Google Colab, you don't need to install the dependencies on your computer and you can save files directly to your Google Drive.

Run with Docker

Pull Image from Docker Hub urbanogilson/sicar

docker pull urbanogilson/sicar:latest

Run the downloaded Docker Image using an entry point (file) from your machine (host)

docker run -i -v $(pwd):/sicar urbanogilson/sicar:latest -<./examples/docker.py

Note: Update the entry point file ./examples/docker.py or create a new one to download data based on your needs.

or pass a script through STDIN

docker run -i -v $(pwd):/sicar urbanogilson/sicar:latest -<<EOF
from SICAR import Sicar, State, Polygon
from SICAR.drivers import Paddle

car = Sicar(driver=Paddle)

car.download_state(state='MG', polygon=Polygon.CONSOLIDATED_AREA, folder='MG')
EOF

Note: Using $(pwd) the container will save the download data into the current folder.

Optional: Make an external directory to store the downloaded data and use a volume parameter in the run command to point to it.
