Meeting Minutes – July 2017 meet


Indian Linux Users Group, Chennai is my homeland. The monthly meetings always give great ideas and thoughts. Most of my project ideas are being initiated here. Kaniyam.com and FreeTamilEbooks.com are childs of the thoughts discussed here.

We meet, every month, second saturday at IIT Madras – 3-6 pm. Last saturday, we had a meet. Here are the notes.

Joshua explained about Yocta project. This is used to build tiny GNU/Linux distributions with only the minimal required tools and libraries. We can create many recipies and use them to design our own OS.

He explained the build tool bitbake and demonstrated the processes.

We can add missing details about the streetname and POI for chennai.

Use these applications to contribute using mobile.
1. maps.me
2. OSM contributor

Using the app, “StreetComplete” we can add missing street names easily.

We can plan for an online or offline mapathon event to learn OSM
contribution someday this month.

I distributed few old “Linux for you” books to the participants.


After the talk, few of us went to gurunath restaurant. Discussed about bitcoin, blockchain, chennai colleges, having hackathon and trainings etc. Baskar selvaraj requested to have more offline events like we were doing few years ago. Remembered contributions of our long time members like KG, Raaman, Bharathi etc. He shared all the fun happening at colleges on the events he conducts. It will be really great if we start more events. Let us plan them and start as soon as possible.

Thanks for all participants and speakers.

StreetComplete – Android app to add Missing Street Names in OpenStreetMaps


I am thinking of bringing OpenStreetMaps.org in Tamil. Imagining a world, where a GPS device or smartphone, showing paths in Tamil and giving instructions in Tamil to the driver.

To achieve this, we need all the street names to be filled in OpenStreetMaps.org

I checked for the streets in my area, Tambaram, Chennai. Found that there are many street names are missing. Editing the street names on the browser seems difficult for the lazy me.

Was looking for any alternate ways to add streets in OSM. Found the Open Source android app “StreetComplete“.

Cover art

It simply shows the streets that dont have a name and ask to enter a name for it. Thats all.

Help to improve the OpenStreetMap with StreetComplete!

This app finds incomplete and extendable data in your vicinity and displays it on a map as markers. Each of those is solvable by answering a simple question to complete the info on site.

The info you enter is then directly added to the OpenStreetMap in your name, without the need to use another editor.

As it says, it is really simple to add details like street names, road types, shops opening hours etc.

Install this app in your android phone and help OpenStreetMaps to have all the street names. It will lead to various super projects like “Maps in our language” and more.

Help to to build truely open maps.

How can we add more data to OpenStreetMaps easily?


File:OSM Logo.svg

When exploring on creating maps in Tamil using OpenSteetMaps found that the current data available on OSM is not equivalent with Google Maps.

We can not copy data from Google Maps and import to OSM as it is a big copyright violation. Yes. We dont have control over the data for the area where we live.

We can do the following.

  1. Look for the data sources who may have the data about the streets, villages, cities. I think think the government departments like Postal, Revenue,Rural development, Public Works may have these data. How can we ask them to share the data in public? Will a RTI help on this? Do you have contacts with the leads of these dept? Please help to get map data from them.
  2. Add the data manually. Edit OSM just like how we are adding content to wikipedia. Drawing roads, marking important places is easy. Watch the below video for a demo.

    By this way, we can add any data manually, edit, improve the existing data. But editing on the browser is not possible for many.

    It will be nice if we have a mobile app to add data to OSM. When I had a smartphone, few years ago, searched for a OSM mobile app. Cant find any app, which helped to edit OSM.

    I dont use smartphone nowadays.

    If you have a smartphoe, can you search for the apps, which can help to edit the OSM easily?

    The app should be very simple. The user should should open the app. It should capture the latitude, longitude from its GPS or mobile tower. Then it should ask for the name of the building,  building number, type of the place, street name, area name,city name, if required a photo, etc. Once the user entered these data, it should be synced on OSM. Contribution should very simple as filling few forms only.

    If we have such app, we can create communities/volunteers to add data to OSM with their smartphones. Just open app, fill data. They are done.

If there is no such easy editing app for OSM, it is high time to create such one. If you are a mobile developer, please create such app and help to build the Openstreetmaps as content rich.

Wondering how the Google, Apple, Bing maps collected data. What kind of mobile app they used, what ate the data they collected. If you have worked for these maps, please share more details about them. It will help a lot.

There may be other easier, better ways to add data to OSM. Please share the details or connect with the communities.

Let us build content rich Open Street Maps.

OpenStreetMap just got a better editor


OpenStreetMap(OSM) just got a better editor to edit the maps. Just sign up, zoom in to your location, start editing, BOOM.

Now, I agree Google Maps are bit sofisticated, but OSM are used by apps like FourSquare, Flickr, Apple maps, many others and definitely it has a huge benefit as a developer and as a normal user who wants to get/update information about his location/business.

Any information that you add into Google is owned by Google, and shown on a service that could in theory be withdrawn at any time (see Google Reader).

Any information you add into OpenStreetMap is licensed freely for people to reuse as they like, so if you’re adding information about your business into OSM, it’s got the potential to be promoted much more widely than if it’s just in Google Maps. The information in OSM will always be available to use as it’s not dependent on any one commercial entity.
