CSDI Unleashes the Power of GIS in Spatial Analytics
I was invited to the Technology Forum, organised by OGCIO, as a VIP speaker for the topic, “Innovate with CSDI Spatial Data to Enhance Public Services,” on 9 March. The event was conducted in hybrid mode and attended by over 4,500 participants. I was asked to deliver a speech on one of two sub-topics: “Improving Decision-making Using Spatial Data Analysis”. The organiser specifically wanted me to discuss GIS spatial analysis using CSDI data for public services.

Government administrators always face the problem of how to utilise limited resources and facilities to meet maximal service demands from their people. This is obviously a spatial problem that can be solved by a classical GIS spatial analysis called location-allocation, which helps find the best locations for facilities to serve a set of demand locations. These locations may try to cover the greatest demand, minimise costs to meet such demand, or maximise market share. The analysis combines the power of GIS spatial analysis and operational research (OR) to offer an optimal solution. Users do not need to bother with the complex OR algorithms operating in the background. They just need to input the necessary datasets and location-allocation will do the rest.
