Building Surveillance in Bangalore leaderboard using Node-Red and CouchDB

I wrote the Surveillance in Bangalore leaderboard using Budibase a while ago. However, I was not impressed with Budibase’s latest changes, so I replaced it with the good old Node-Red flow. Node-Red is already running at my home, so installing it was not required. Since the data was always stored on my instance of CouchDB, I didn’t have to do any migration there. I moved the automation to Node-Red And viewed it using HTML and CouchDB Views.

Data: Public, Private and Beyond

Linked List: Three Android Apps to Efficiently Contribute to OpenStreetMap

From a browser, I moved to contributing using GPS Logger or OSMAnd. That made my workflow a lot easier, but these apps are not for editing maps but for regular map use. They are okay if you are not mapping frequently or in mass. So editing flow in these apps is not seamless. Hence I continued to explore other options.
