The Data exists...right under our Mouses !

The capital irony

It is perhaps a capital irony of our times that precisely at the time when computers are more powerful and affordable than ever before and the access to powerful and previously expensive software provided by the  Linux + FOSS (Free and Open Source Software) movement, the general ability to use computers effectively to address the various problems faced by our cities is at an all time low.

I myself come from a background of primarily qualitative and participatory techniques in urban planning. I continue to have a natural fondness for such techniques, but have increasingly also discovered the power that effective use of computers bring to my work.

Contrary to the myth that the quantitative and qualitative worlds are poles apart (which leads to the further myth that professionals dealing with qualitative techniques cannot use computers for serious quantitative analysis), the two are in fact friends and allies of each other and help each other continuously.

Without waxing complex, think of a rather simple example. I would like to undertake participatory exercises in various slums in my city and I use all kinds of creative ideas to undertake the same inside those communities.

But alongside that, I could also prepare a GIS database of the slums in the city that gives me spatial and quantitative information on slums - such as their location, distance from each other, distance from other city facilities, size and density of the settlements, the population and occupational characteristics of the settlements etc.

This quantitative database can actually help me increase the effectiveness of my qualitative techniques by helping me to schedule meetings, use different techniques in slums of different sizes and shapes, check the probability of consensus-building (fewer meetings could build consensus faster in a smaller slum than in a larger and denser slum) etc.

Rather than focusing too much on whether to deploy quantitative or qualitative methods, it is better to focus on the problem that needs to be solved and deploy whatever methods that may be necessary.

Why computers ?

As long as I want to do participatory activities in a handful of slums, I may not need any support of computers at all. However, if I would like to undertake such activities in tens or hundreds or thousands of slums, then I begin to feel the need of the processing power of the computer.

It is as simple as that.

As more and more resources are made available to various urban development programs and schemes in India, their sizes, duration and scale of operation are all increasing. It is not difficult to understand that in a country the size of India, urban development projects would need to be undertaken at a scale where one can at least hope to make a meaningful difference. 

But of course, computers need instructions to follow - and they need data to work on.

The data exists...right under our mouses

Quite often, the impossibility of obtaining data is cited as one of the main barriers to effective use of computers in solving urban problems in India. I have written on this topic on multiple occasions. And I have stressed on earlier blogs that mere accumulation of digital data is not of much use if one does know how to use computers effectively to process it.

However, another capital irony of our times is that much of the data whose absence we so lament - does indeed exist...and sometimes right under our noses (or mouses).

Let me demonstrate.

This particular link will take you to the dashboard of the "GIS based Master Plan" sub-scheme of AMRUT. 

The very first component of this sub-scheme was geo-database creation and in the following screen-shot of the dashboard we can see its status -

 

If we look at the first three steps of the component, we can see that satellite data had been acquired and processed for about 450 cities. In the pie chart on administrative works is not self-explanatory, but it could mean that the National Remote Sensing Centre (NRSC) of the Indian Space Research Organisation (ISRO) may have handled the satellite data acquisition and processing for 240 cities and private companies may have done it for another 220 cities.

In any case, according to the official dashboard itself, we can conclude that processed satellite data exist for about 450 cities. As per the status chart, final GIS maps also seem to exist for 351 cities.

From if it exists...to where it exists

Finding evidence and clear arguments for the claim that something exists, is the first step in finding something. If I know for sure that something exists, then I need not succumb to the fallacy that it doesn't even exist. 

The task after that is to discover, where it exists, rather than wonder if it exists.

The same method can be applied to understand exactly what all data has been collected and processed under the myriad central and state government schemes that are going on in the country and have already been executed in the past.

Believe me, we will have more data than we would need for getting most of our tasks done.

The catch here is this...a person who does not have the imagination to discover the data, most likely would not have the imagination to use that data either.

But let's keep that blast for a later post ;)
