[South African Chapter] Mapping Urban Vulnerability areas (Crimes, Disasters, etc.) Using Open Source Data

Challenge Started!

This Omdena Local Chapter Challenge runs for 6 weeks and is a unique experience to try and grow your skills in a collaborative and safe environment with a diverse mix of people from all over the world. 

You will work on solving a local problem, initiated by the Omdena Johannesburg, South Africa Chapter.


The problem

Many frameworks on the performance of cities generate urban profiles at the city scale, providing limited or no information on the performance of different city sub-units such as districts, wards, zones, settlements, or blocks. The transformative focus of the Agenda 2030 of Leaving no one Behind aligns with the local policies of many cities, their intervention focus being the reduction of spatial inequalities.

Mapping spatial inequalities within the city guide the identification of vulnerable areas, which can be expressed on a continuous scale of vulnerability. Many forms of spatial vulnerabilities such as poor access to basic services, lack of green cover, crime and insecurity, vulnerability to disaster risks, access to opportunities, and access to cultural infrastructure among others, have statistics that can be standardized for comparison and mapped – where data is available. The individual layers of vulnerability as well as the composite layer combining the layers are useful for spatially targeted intervention by city administrators and other actors.

In extension, cities may prepare profiles for their settlements based on a set of indicators to guide city residents in understanding their settlements, and service providers in setting their intervention priorities.


The project goals

The AI solution should identify key characteristics of urban vulnerability and generate data layers on them from city-level data, open data sources, extraction of data from imageries, and/or complementary sources. The analysis could involve the creation of surface maps for each form of vulnerability and aggregating the layers to generate a composite ‘city vulnerability layer’.

For useful results, the resolution of the data must be good to enable precise identification of vulnerable locations within the city fabric. Identification of locations with multiple vulnerabilities may guide decision-makers on deteriorating locations, especially when monitoring is done at a consistent temporal scale.


Why join? The uniqueness of Omdena Local Chapter Challenges

Omdena Local Chapter Challenges are not a competition or hackathon but a real-world project that will grow your experience to a new level.

A unique learning experience with the potential to make an impact through the outcome of the project. You will go through an entire data science project lifecycle. This covers problem scoping, data collection, and preparation, as well as modeling for deployment.

And the best part is that you will join the global and collaborative community of Omdena with tons of benefits to accelerate your career.
