Province-level clean-up tasks:

To do

• Review bridge name. Fix issues. (e.g. spelling out abbreviations, fixing typos, etc.)
  • Follow the Formatting & Style Guidelines.
  • Post questions here in Github, or ask questions in the temporary Telegram channel.
• Review the BRGY, MUN values again. They've been given a quick pass, and another pass is helpful.
  • Some BRGY values are missing. Try to identify them, if you can.
  • Records are grouped by province, and in most cases, it's possible to finish each in one sitting.
• Please finish your selected task before selecting another task. Do not "reserve" tasks.
• Put a tick mark on your selected province and download the corresponding file from the pre-processing folder. Use your favorite editor for the data clean-up.
• Once you complete the task, upload the file via a PR request or thru the Telegram channel. See the readme.md

I used a script to do some mass-cleanup (see my fork)

Result is in a googlesheet for easy review: https://docs.google.com/spreadsheets/d/1tPG7NJx7EuEXjY7HCg8oY9Cyqwz1H0JrXsSf5dyE_k0/edit#gid=893538581

Barangay/Municipalities are mostly fixed automatically. To give you an idea, this is the code:

function cleanName(str) {
    return str
        .replaceAll('Br.', 'Bridge')
        .replace('(NB)', ' (Northbound)')
        .replace(' NB)', ' Northbound)')
        .replace('NB)', ' Northbound)')
        .replace(' NB ', ' Northbound ')
        .replace('(SB)', '(Southbound)')
        .replace(' SB ', ' Southbound ')
        .replace('(WB)', '(Westbound)')
        .replace(' WB ', ' Westbound ')
        .replace('(EB)', '(Eastbound)')
        .replace(' EB ', ' Eastbound ')
        .replace('Gov. ', 'Governor ')
        .replace('Arch Reyes', 'Archbishop Reyes')
        .replace(/(.*)( \d)/g, "$1 №$2")
        .replace('  ', ' ')
        .replace('  ', ' ')
        .replace('( ', '(')
}

function cleanMunicipality(str) {
    return str
        .replace(/\s+/g, ' ').trim()
        .replace(/$\s(.*)/, "$1")
        .toLowerCase()
        .split(' ')
        .map(word => word.charAt(0).toUpperCase() + word.substring(1))
        .join(' ')
        .replace('Sta.', 'Santa')
        .replace('Sta ', 'Santa ')
        .replace('Zambonga City', 'Zamboanga City')
        .replace("Brookes Point", "Brooke's Point")
        .replace("Brook's Point", "Brooke's Point")
        .replace("Busuanga, Palawan", "Busuanga")
        .replace(", Cebu", "")
        .replace(", Sorsogon City", "")
        .replace(", Ilocos Norte", "")
        .replace(", Rizal", "")
        .replace(",lanao Del Norte", "")
        .replace(", Lanao Del Norte", "")
        .replace(", Agusan Del Sur", "")
        .replace(", Province Of Dinagat Islands", "")
        .replace(", Leyte", "")
        .replace(", N. Samar", "")
        .replace(", Quezon", "")
        .replace(",zds.", "")
        .replace(", Cam. Sur", "")
        .replace(", N Samar", "")
        .replace(",capiz", "")
        .replace(", Ilocos Sur", "")
        .replace(",zamboanga Del Sur", "")
        .replace(", Zamboanga Del Sur", "")
        .replace(" ,tarlac", "")
        .replace(", Albay", "")
        .replace(", Palawan", "")
        .replace(", Northern Samar", "")
        .replace(",tarlac", "")
        .replace(", Zds.", "")
        .replace("Sergio Osmena, Sr.", "Sergio Osmeña")
}

function cleanBarangay(str) {
    return str
        .replace(/\s+/g, ' ').trim()
        .replace(/$\s(.*)/, "$1")
        .toLowerCase()
        .split(' ')
        .map(word => word.charAt(0).toUpperCase() + word.substring(1))
        .join(' ')
        .replace('Brgy. ', '')
        .replace('Bgy. ', '')
        .replace('Barangay ', '')
        .replace('Sta.', 'Santa')
        .replace('Sta ', 'Santa ')
        .replace('Sto.', 'Santo')
        .replace('Sto ', 'Santo ')
        .replace('Brgys.', 'Barangays')
        .replace('Brgys.', 'Barangays')
        .replace('Pob.', 'Poblacion')
        .replace('Pobl;acion', 'Poblacion')
        .replace('Herero-perez', 'Herrero-Perez')
        .replace('New Bususnga', 'New Busuanga')
}

There are still 69 missing Barangays, and 19 missing municipalities. Some are not "clean" yet (having region in it, or messy formatting for multiple Barangays).

I stuck to using " № X" for bridge numbering, it seems the cleanest.

Hope this helps, let me know if anything needs adjustment.
