ictiopy 1.0.1

Parse observations from ictio.org's Citizen Observatory

IctioPy

Python3 data access library for ictio.org's Citizen Observatory for Amazon basin fish observation.

This python module provides helper routines for citizen scientists that want to load and analyse data from Ictio's citizen observatory for Amazon basin fish observation. The data from this Citizen Observatory is not freely available via public API nor public download, but it can be downloaded as a zip file after registration in web page.

Features

This module takes an Ictio_Basic zip file from ictio.org and performs the following tasks on it:

1. unzips its contents to a secure temporary folder
2. flattens decompressed file and folder structure to make file paths more predictable
3. autodetects the name of the observations file, which has a changing name based on the db generation date
4. verifies the existence of "taxa" file, containing a taxonomy of species in Amazon basin
5. loads observations and taxa files into dataframes
6. combines information from both dataframes into one, so observations are complemented with species data
7. sanitizes and curates the structure and the values
8. and returns a curated dataframe with all relevant data ready to be analysed

The structure of the dataframe is as follows:

Observation related data:

obs_id: Unique observation ID.

user_id: Anonymous, numeric ID of the user that made the observation.

protocol_name: Name of the observaton protocol used in the observation. Possible values: During Fishing, After Fishing, Market Survey and Port Survey

Chronology related data:

obs_year: Year of observation.

obs_month: Month of observation.

obs_day: Day of month of observation.

Location related data:

watershed_code: Unique identifier for watershed. For Ictio hotspots and personal locations, the watershed code and watershed name are inferred based on geographic position of Citizen Scientist at the time of observation.

watershed_name: Name of the watersed in which the osbervation was made.

port: This is the name of the port where data was collected and is only reported with the Port Protocol. This is not the location where fish were caught.

location_type: Ictio has three location types: Watersheds, Ictio Hotspots, and Personal Locations. This field will identify watersheds and Ictio Hotspots. This field will be null for personal locations. A personal location is any new location added with the upload tool or based on raw GPS coordinates.

country_name: Country in which the observation was made.

state_province_name: State/Province Code, automatically assigned by latitude and longitude. If there is a checklist assigned to a watershed, observation will be assigned to the State/Province where the centroid of the watershed is. If the watershed overlaps a boundary, it could be assigned to a different State/Province.

Species related data:

taxon_code: Species taxon code.

scientific_name: Scientific name of the species observed.

category: Category of the species observed^*.

order1: First order of the species observed^*.

family: Family of the species observed^*.

^*This data does not come from observations table. It is pulled from the separate taxa table that comes embedded in Ictio_basic zip file. The value of taxon_code (present in both tables) is used to perform value lookup.

Fishing related data:

complete_checklist: Indicates if the checklist was completed. A complete checklist is when all taxa caught during the fishing effort are reported. In a market survey it would be all taxa observed at the market. If observation was made via app, it is assumed that user reported a complete checklist.

number_of_fish: Number of individual fish reported for the given taxon.

weight: Total weight in Kg reported for the given taxon.

price_local_currency: Price per Kg in the local currency for the taxon.

fishing_duration: The duration of the fishing effort in hours.

num_of_fishers: Number of fishers participating in fishing effort.

NOTE: At the time of this writing (May 2022), the ictio.org's observation database contains +86.400 observations. Please bear in mind that processing the data can take more than 10 seconds. Your mileage may vary.

Installation

as usual:

pip install ictiopy

Usage

• First, register an accout at ictio.org (don't forget to read terms of use).
• Second, download data and store zip file locally in your hard disk.
• Finally, use this code in order to obtain a ready to use Pandas dataframe with Ictio's observation data:

from ictiopy import ictiopy
pandas_dataframe = ictiopy.load_zipdb('path/to/Ictio_Basic_yyyymmdd.zip') 

About Ictio.org

Ictio is a database and a mobile phone app created to register observations of caught fish in the Amazon basin. It was developed as part of the Citizen Science for the Amazon project, which aims to connect citizens in the collection and sharing of information on the most important Amazonian fish species. Its wider objective is for that information to contribute in understanding Amazonian fish migration.

Ictio.org is a project of The Cornell Lab of Ornitology. Please, read Ictio's terms of use before using its data.

About MECODA and COS4CLOUD

This data parsing library has been specifically developed for MECODA, a toolkit built around Orange Data Mining for Citizen Observatory data analysis.

MECODA is part of the technological services for Citizen Observatories that are developed in the context of COS4CLOUD project, funded by the European Union’s Horizon 2020 research and innovation programme under grant agreement #863463.
