Quantity vs Quality Assurance

I wanted to know how well I was performing as an armchair mapper, internally I was concerned that I was creating more issues than I was helping so I learned about a website that answers the question “How did I contribute?”.

On my name I looked at the quality assurance section and the quantity of errors was too very high, almost over a 4000 issues ignored. I have attempted to improve the quality of my mapping change sets using Osmose and OSMI.

Osmose

Initially I had 26 level 1(major) issues, 50 level 2(intermediate) issues and 800(minor). I quickly adjusted the level 1 issues and over half of my level 2 issues. I have a single level 1, 19 level 2 and over 700 level 3 issues. Systematically I hope to solve; *amenity=parking issues *building=construction issues *building overlap issues *waterway issues.

Overview

This is inspired by laambda19’s diary post on their mapping project, I want to document my work the same way with clear examples of before and after, adding more detail to the Bulawayo map. Aerial photography and local knowledge are the main driving force in mapping. There is scarce information available online, what little there is often requires a Facebook account.
