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.

CLI for Readlist

I maintain the readlist in a CouchDB database. Each feed (channel) is a document in that database. I use the file’s name as the primary key i.e “_id”. For example, “sri-lankas-economic-crisis.json” is the key to the Sri Lankan Economic Crisis reading list. It’s a single document. It has many feed items like any JSONFeed. The first few were easy to create and manage. But then I needed something simple to manage this if I was going to be serious about using it.

Simple Readlist viewer

Until now, I have been usingreadliston JSONFeed readers. But one of the reasons to have a readlist is to share it with friends. So I thought of a page that lists the links with some description. So now I have a simple page that does just that. It fetches the JSONFeed of a readlist and displays the articles as a list.

How to Download Surveillance in Bengaluru Data

Everything we map goes directly to OpenStreetMap. The data on OpenStreetMap is available for free under ODBL. The easiest way to download Surveillance in Bengaluru data is from Overpass Turbo. I have written some queries below that you can use on Overpass Turbo to get the data. I also have a demo video for you.

Webhooks from Android Apps

Webhooks don’t have to be from a traditional server to a web server. Webhooks can come from any software component which can connect to the internet (or intranet) and send HTTP requests.

Readlists

I love readlists. After it closed down, I used the pinboard’s tag as a way to share it. For a long time, I wanted to own the process and data. Now I do.
