(in unlikely case of people actually looking for more things to fix - what you are looking for? I likely can share something from my TODO list - posting all of it here would be pointless but if people are actually looking for something…)
in both cases I fixed some, put on my TODO list to finish it but I see that I will not get to it before 2050 at the current rate. So if anyone is interested, feel free to fix mapping there!
Last year we did a province of the month project. Each month one Dutch province was targeted by the community, to get some of these missions done. Many mappers contributed with work and special skills (eg QGIS) and resources (public data, contributed data). Some missions reached near-completion in this one year!
I don’t know how this applies to your CFH, but I found it encouraging!
