The Usefulness of OpenStreetMap in Disaster Relief

by mr november

Immediately after the massive 7.8 magnitude earthquake that hit Nepal on Saturday, 25th April 2015, the Humanitarian OpenStreetMap Team [HOT] activated a huge user-contributed effort towards mapping various areas of the affected region. Along with organizations like Kathmandu Living Labs and Mapbox, HOT has enabled 3,461 users all over the world to contribute to OpenStreetMap [OSM] of Nepal till now. Around 57,000 edits have been made in the past four days by users, 2061 of whom are new users, registering just for this task [1]. These maps help relief and rescue organizations on the ground to reach affected areas and citizens.

Facilitating a link between the OpenStreetMap Community and the traditional crisis / disaster response teams, has been the main role of HOT. They have helped setup voluntary user contributions and mapping tasks during disasters like the Haiti earthquake, Ivory Coast Election Crisis, Ebola Epidemic in West Africa and Somalian Drought & Famine Crisis. Kathmandu Living Labs is a group of young technology enthusiasts who have remarkably brought together open source, open data and civic technologies to solve difficult issues. Along with Mapbox, an agency that specializes in maps, spatial data and Geographical Information Systems, they are actively working on HOT OSM tasks.

Since Sunday, 26th April 2015, users have been able to map in great detail about 10,000 sq. km of the affected area, “including coverage of road networks, hiking trails, built-up areas, building footprints, river crossings and temporary relief camps.” [2]

How are maps useful for relief and rescue work?

Maps are valuable tools for humanitarian work. They allow for a strategic understanding of different parts of affected regions, such as road networks, residential areas, types of land use (industrial, agricultural) and so on. This helps relief and rescue agencies to identify all locations, how to reach them and what kind of a topographic landscape to plan for. So in a natural disaster like an earthquake, one of the many ways a detailed map can help is to identify locations where camp sites (Internally Displaced Persons – IDP Camps) can be setup. Mapping a network of roads, paths and tracks is another very useful task, since the data it generates is highly valuable for distributing aid and relief services.

Organizations like Red Cross and MSF (Doctors Without Borders) work closely with HOT for maps.

What is OpenStreetMap and how is it different from Google Maps?

OpenStreetMap, or OSM, is like a Wikipedia of maps – all data on these maps is user contributed. And unlike Google Maps, this data is freely available for download, distribution, adaption and use. This means that such map data can be used offline and for particular needs of different situations. You can create a map of power lines running through a country to see the reach of the electrical grid, if ever the need arises.

This makes OSM indispensable for humanitarian work. Map data of Nepal contributed by users is available here and here – these are updated every 30 minutes. This can be used to print physical maps, used on smart phone apps like OSM that work offline and even support voice navigation, and on GARMIN GPS devices. [2]

Latest satellite imagery, as recent as 27th April 2015, is available to OSM, making the map up to date and useful.


 

Everyone can contribute to these mapping efforts. Visit the HOT website to get involved. To volunteer for Nepal Relief Maps see this document put together by Datameet.

Contemporary Artists and Their Unquestionable Freedoms

by mr november

Dear Russell Peters,

You think that a roast is just being honest about someone, in front of that someone, and that the AIB knockout was great comedy. To an extent, I agree with the first part of this, sure, and I don’t care what you think of Aamir Khan.

But please, by all means, tell us how this means that a comedian (a real artist according to you) can ‘speak the truth’ about a person’s dark skin by joking about an entire race, about how they were – and are – treated like shit on the basis of their skin colour, about how an epidemic is taking their lives and goes unnoticeable until white people get affected by it. Does it also mean that a comedian can make fun of the sexuality of so many people who are shamed and humiliated by society, because one person on their stage happens to be okay with it? I could go on and on with references.

5 Saal Kejriwal: Great Expectation from the Aam Aadmi Party

by mr november

The sweeping victory for Aam Aadmi Party in the Delhi elections is a reaffirmation of hope for many. The saffron Modi Wave has been pulled down, it has hit the rocks and dispersed into Delhi’s chaotic order. And now comes the real challenge.

Delhi is the capital of this country. It is where the hopes and aspirations of millions of people collide. The culture of Delhi is a complex mix of innumerable cultures from not only neighbouring states and cities, but many distant places as well. To name a few – Bengalis, Malayalis, Tamilians, Nagas, Assamese, Nigerians, Burmese Rohingyas, Kashmiris, Marathis, Andhras, Arunachalis, Nepalese, Somalis, Afghans; all of us are Delhiites. We are Buddhists, Hindus, Muslims, Sikhs, Christians, Jews, None of The Above; all of us are Delhiites. All of us are the Aam Aadmi that AAP claims to represent.

on the bloggability of thoughts.

it’s funny how often i get news about my neighbourhood from a newspaper hundreds of miles away. funny how, no matter how hard i try to be up to date, to be keyed in, to allow myself the space and depth to think about as many things as possible, usually i get most of my ‘information’ from my facebook newsfeed, unfortunately the one intangible …(what to call it? it isn’t one screen, it isn’t one piece of paper, it’s a ‘feed’, a word that has now lost its most basic tangible meaning. tangibility, if you couldn’t tell, is really important to me) source my eyeballs are witness to the most in a 24-hour span.

so, beyonce sampled chimamanda ngoze adiche, and hauz khas socialities wondered aloud “so cool!… how do you pronounce that again?” six feminist blogs talk about beyonce and nicki minaj, adoration and mixed responses, respectively. some shade thrown on nicki, and six more thinkpieces on racism within feminist movements. one reasonably argued piece (personal opinion, hashtag hashtag) about how something can be problematic in a capitalist cultural context even if put forth by an independent strong black woman (Hi, Oprah).
