Building the Venezuela hydrologic map was an R & RStudio masterpiece! 💻✨
I used the terra, elevatr, sf, geodata, rayshader, packages to process the river data, create the elevation model, and render the final 3D view.
What's your favorite R package for maps? 👇

This map relies on a Coordinate Reference System (CRS) to be accurate! 📐🌐

Before I leave, I want to thank Jesús Ojeda for his help at the beginning of this project, with his guidance I manage to understand how to scrape the data. It's good to have an amazing community of people to turn to for this kind of thing.

The two datasets include: (i) National Assembly, and regional with 6667 candidates (3066 females and 3601 males); and (ii) municipal with 15789 candidates, which include 7199 females and 8590 males. And there are 11 types of elections in this cycle.

I used Python with the AIOHTTP and AsyncIO libraries to communicate with the web server and iterate through all states, municipalities and districts to create JSON files for each type of election at the candidate-level.

Thank to Giuseppe Gangi and his video, I got the idea to collect this data using web scraping techniques. And I asked a colleague who helped me kickstart this project that could spark potential research of women ballot placement on authoritarian settings.

Again, they didn't bring back up their official webpage and instead they used doe.postulaciones.org.ve/eanr2025 and doe.postulaciones.org.ve/em2025 to publish the list of candidates, of course these sites were temporal so I had to act quickly to collect the data.

The CNE, lacking transparency and autonomy, programmed this year the regional and parliamentary elections for May 25th and later the municipal elections for July 27th. The time for the campaign was cut short and it was just a few weeks in order to favor the regime.

Now, the CNE webpage only exists in the archives of the Wayback Machine, thanks to the @archive.org project. Unfortunately, not all data is there but at least this shows the time when they were supposedly attacked and never came back.

Timing was essential for data gathering, because the National Committee Council (CNE in Spanish, the electoral management body in Venezuela) reported they were under a cyberattack during last year's election, and their webpage hasn't been up since then

t's time for another #1Week1Project📅💻, this time I'll discuss the process of creating a dataset of electoral data using web scraping techniques.
This is part of the Gender Parity Analysis in Authoritarian Elections project that takes the country-case of Venezuela.

This project is part of a cross-disciplinary collaboration with the Anthropologist @FidelRodV who is interested in characterizing the slave trade voyages and the differences across Southern Caribbean ports.

Before I leave, on the @slavevoyages website there is also a People Database that includes registry of over 90,000 enslaved and over 30,000 enslavers. This big dataset can also be used to kickstart research on these topics.

Finally, I leave this short descriptive analysis if the data with this plot comparing the flag of the vessel between Intra-American and Trans-Atlantic voyages. Again, there are stark differences, Intra-American are dominated by the British while the Trans-Atlantic by the Dutchs.

There are also different trends in trade voyages arrival by region, I believe they vary based on the characteristics of the ports of disembarkation and the needs of labor from each of the regions. This is one of the conundrums this research aims to address.

It is interesting to see the differences in outcomes by type of journey, Intra-American voyages, shorter in distance, are more secure than Trans-Atlantic ones. Of course, these are observations from preliminary and descriptive analysis.

It's worth noting that the Trans-Atlantic voyages not only come from West Africa, but also include East African ports.

This map from #SlavesVoyages roughly shows the area of study. After creating the sample dataset, forty ports in the Southern Caribbean are included, it contains 4,502 voyages (2,794 Trans-Atlantic and 1,708 intra-American).

While the impressive dataset covers four centuries and most of all the voyages occurred in that era through the Atlantic Ocean and the Caribbean Sea, our focus for this particular project will be mostly on the Southern Caribbean.

After data cleaning, there are 74,117 voyages, 37,777 Intra-American and 36,340 Trans-Atlantic. Here you can visualize the trends of each type of journey throughout the years. At the beginning of the XIX century, Intra-American voyages surpassed Trans-Atlantic ones.

I first noticed this data comes from historical records, and most of the 49 variables have missing values, which is understandable. But thanks to imputation methods, some variables have very low levels of missingness and can be used for this project.

The datasets used on this project can be downloaded from the #slavevoyages site: slavevoyages.org, the "Voyages" section allows you to explore the data online and even has dynamic map visualizations that display slave voyages throughout the 1500s to the 1800s.
