/ Rainfall data
As a 'what to do at home' activity I am thinking of volunteering for this project alongside my other community ones.
Does anyone on this forum do it and how much work does it entail?
Yes, I'm doing that.
It's no problem, you can do a few at a time, leave and come back etc. However you'll get sucked in by looking at the old records and end up spending longer than you planned. They're brilliant!
I was transcribing place names in Ireland and trying to make sure I had the names correct. However the grid references they put seemed to come out in the middle of the Celtic Sea when I plugged them into an online finder. No doubt my bad.
I read about this, and wondered why they don't OCR the data first (especially as it's tabular already), then get volunteers either to check it, or to retype/edit/amend it. Would make much better use of people's time and the technology available. I imagine they have some inbuilt checking anyway, e.g. by getting two people to do the same sheet independently, then comparing the results, but OCR would help move things along a bit quicker?
Thats what I thought.
I'm currently learning python at the moment and it seems like it wouldnt be tooooooo hard to make a python script to automate it (for someone with more knowledge of the langauge than me atleast!)
They probably have, but you would need to validate the software so you need some manually input data to use as a reference.
If the manually entered material is ready before the OCR then they won't even finish the work.
I've done it a bit. As for doing digit recognition in Python or whatever, I suspect the accuracy is higher if actual people do it. Perhaps a deep learning image recognition expert will correct me on that.
It's therapeutic just to do a few now and then.
I saw a fascinating undergrad presentation last year where they made use of data similarly transcribed from the logbooks of 19th century whaling ship captains.
Email from the people hosting the project:
"new project Rainfall Rescue, which asks for your help to transcribe old weather records, has broken records, getting nearly half a million classifications in its first day."

I think I have discovered the answer to this - they are using the Irish grid reference system:
I was seeing references like IH230123 which made no sense, however assuming the "I" stands for "Irish" (since that letter doesn't exist in the classification system) you end up with H230123 - which works!
