Mapping Sidewalks in Kottayam City

Posted by SM@Edit on 14 March 2016 in English (English)

Road Transport Network in the city

Made an attempt to map some of the sidewalks in Kottayam City. Kottayam has a well established Road Transport Network provided by private parties as well as the government, so there is always a good number of vehicles inside the city. Using sidewalks ensure the safety of pedestrians. In a city like Kottayam, some of the major roads do not even have sidewalks. Hence I decided to take a stab at mapping some of the important ones in the city as a first step to provide a pedestrian/wheelchair friendly map for the city.

Mapping Alternatives

I decided to map the sidewalk a separate way next to the road for the sake of simplicity. Would like to know if adding a separate geometry is considered redundant and makes the maintenance more difficult. Is it better to tag Sidewalk as refinement to a highway?

Limitations/ Next steps

Also noticed that the satellite imagery does not display enough details to complete the mapping mostly due to tree cover and other features blocking the view. Will need to personally visit the city with a GPS device and record the details before I can complete the side walk details for the entire city.

This is an amazing exercise. We have really poor footpath infrastructure in India, especially in terms of accessibility for visually impaired and those on a wheelchair, although I suspect Kerala is far ahead on these matters.

Every community has their own approach to tagging footpaths as separate ways. I'm for mapping them separate especially in town centers with heavy foot traffic, this allows for much more precise pedestrian routing. But on residential roads, it makes more sense to have it as an added attribute sidewalk on the road.

Thanks for the inputs. Matches what I had in mind as well
