After discussing with the creators of OSMCha and MapRoulette, both projects will become OSM US Programs. This transition enables OSM US to allocate a portion of our main budget to support the maintenance and development of both projects.

Our #osmcha instance makes it easy to inspect large changesets for subtle changes. Sometimes, those changes look very wrong, but only because modern aerial imagery doesn’t line up with the historical features being mapped.

Now you can visualize changesets […]

#OpenStreetMap: I was wondering what an OSMCha Frontend would look like with a modern tech stack. So I took some time during my vacation to find out: https://github.com/tordans/osmcha2/issues/1. Anyone good at NextJS and eager to use a fresh OSMCha frontend? Maybe we can finish this over time…

Also lost of love to @Mapbox's #OSMCHA: I can now easily patrol changesets in my #Openstreetmap area of interest. https://osmcha.mapbox.com - for that specific purpose it offers a nice integrated experience, though @ilyazver's #WhoDidIt remains useful for general activity awareness

⁦@fofliajinal⁩ A Case Study of OSMCha at #SotMAsia18 it was interesting to hear about the user experience research process with the tool built around OSM https://t.co/jBwb8Nlh8t

#osmcha can visualize giant changesets without timing out or throwing an error. No one will sneak another empire into OHM without the community noticing it.

特に、既存の道路の線形を直すような時とか
間違えておかしなところを曲げていないかといった確認のためにOSMChaを使うと良いんだけど
直す過程で消した全ノードが分かるので、番号の大きさから「ほ~、そういう順番で追加されていったのか」みたいなことを考察すると楽しい
当然、歩道は道路よりも新しい(分離する方法が後からできたので) #openstreetmap

突然、OSMの履歴に見慣れない表示が追加されてびっくりした
どうやらOSMChaに類似した「追加」「変更」「削除」の内訳が追加されたらしい
追加された瞬間はUTCで8時16分ごろ(日本時間17時16分ごろ) #openstreetmap
