PSARPS - Planet Scope ARPS Satellite Imagery Metadata Tool

A Python library and CLI tool for retrieving tide metadata for Planet Scope ARPS (Automated Rapid Preprocessing System) satellite imagery.

Features

• Extract acquisition time from ARPS QA raster images
• Find the closest tide station to the image location
• Get the tide height at the time of image acquisition
• Simple command-line interface

Installation

From PyPI

pip install psarps

From GitHub

pip install git+https://github.com/tayden/psarps.git

Usage

Command Line Interface

Get tide information for a Planet Scope ARPS QA raster image:

arps info path/to/your_image_qa.tif

Example output:

Acquisition Time: 2023-05-01 14:30:45
Tide Height (m): 2.34
Station Name: Victoria
Station Distance (m): 5432

Python API

import psarps

# Get tide information
tide_info = psarps.get_tide_height("path/to/your_image_qa.tif")

# Access the tide data
acquisition_time = tide_info['acquisition_time']
tide_height = tide_info['tide_height']
station_name = tide_info['station_name']
station_distance = tide_info['station_distance']

# Get just the acquisition time
acq_time = psarps.get_acquisition_time("path/to/your_image_qa.tif")

# Get the closest tide station
closest_station = psarps.get_closest_tide_station("path/to/your_image_qa.tif")
