Greetings, I am working on OSM predominantly in the Blue Mountains, in New South Wales, Australia. I mostly like to map land use and public utilities/infrastructure, but am aiming to be a mapping all-rounder. I am quite active on Mapillary with 360 street level imagery; please see my diary entries for more details about my low-cost setup.
I do not import or use AI generated data to map; rather I focus on upholding high data quality standards with manual verification.
Please check out my web app “Osmia” (currently under development) for detecting old geometry:

I am active on OpenStreetMap World discord in the Oceania channel; you can join here, and in #rules-and-roles click the 🇦🇺 flag emoji to gain access to #Oceania.
