Are there websites where I can do simple tasks like distinguishing/sorting images, writing captions, selecting correct options or other tasks I can do in my free time or mindlessly whilst also contributing to meaningful projects? Something like Google Crowdsource, although I would like to avoid registering to any privacy invading services asking for my personal info in order to contribute.
Great that you are looking for a way to contribute to something meaningful. OpenStreetMap aims to create a free map of the world, at detail levels nobody else does. Besides the obvious, it helps groups that are marginalized (how do I navigate as a blind person? Where are safe spots to cross the street? Does this restaurant not only have a ramp for my wheelchair, but does it also have restrooms that accommodate for my needs?)
The simplest way to start is to contribute on https://pic4review.pavie.info/ - here you can basically look at pictures other people have taken, answer some questions and thus add data to OpenStreetMap.
OSM is perfect for this. If you want a wider range of prompts, and you have an Android device, you can use https://streetcomplete.app/ - it turns every missing data point into a “quest” and gamifies it. It’s really addictive when you get into it. :)
Actually, the link I shared was info from Streetcomplete. This app is the reason I went back to Android, such an amazing project!
Oh cool :)
OSM is fantastic, but I want to direct OP towards their Humanitarian Aid page where you can contribute to emergency mapping projects: https://www.hotosm.org/
Absolutely. This has even more impact, but also a higher learning curve (OP asked to answer questions). I contribute on HOTOSM as well, it is an amazing project!
