PROJECT DESCRIPTION

Our project aims to make use of geospatial intelligence to explore the potential of allocating nearby doctors within estates to the residents, in particular the elderly to combat the issues of an ageing population.

PROJECT MOTIVATION

Between 1965 and this year, Singapore’s population grew from 1.9 million to 5.71 million. However, the number of citizens aged 65 and above is increasing rapidly, as population growth slows. The size of this group of citizens doubled from 220,000 in year 2000 to 886,000 today, and is expected to increase even more by 2030. As the government look towards new ways in providing better social welfare, we aim to explore the possibility of allocating neighbourhood clinic doctors to nearby HDB blocks to ensure that those with mobility issues or disabilities receives adequate healthcare.

PROJECT OBJECTIVES

Our goals are :

• To build a GIS tool (an R Shiny app)
• Analyse the demand and supply of clinics using the proximity of each clinic in residential zones
• Evaluate results of analysis and provide recommendations to further improve the social welfare for the residents who require special assistance

DATA COLLECTION

To achieve our project objectives, it is necessary for us to obtain the datasets that is available online for use. The following table depicts the list of datasets we require and how we can obtain them:

No.	Dataset	Description	Source(s)
1.	OSM Layer (Singapore)	This dataset is necessary for us to be able to plot the Singapore map.	OpenStreetMap
2.	Singapore Planning Subzone (MP14_SUBZONE_WEB_PL)	This dataset is necessary for us to be able to plot the Singapore map out at a planning subzone level.	https://data.gov.sg/dataset/master-plan-2014-subzone-boundary-no-sea
3.	Estimated Singapore Resident Population in HDB Flats	Find out the number of residents per estate.	https://data.gov.sg/dataset/estimated-resident-population-living-in-hdb-flats
4.	Dwelling Units under HDB's Management, by Town and Flat Type	Shows number of units per estate for each flat type.	https://data.gov.sg/dataset/number-of-residential-units-under-hdb-s-management
5.	Residents by Age Group & Type of Dwelling, Annual	Shows age group and number of residents by type of dwelling.	https://data.gov.sg/dataset/residents-by-age-group-type-of-dwelling-annual
6.	Singapore Residents by Subzone and Type of Dwelling, June 2016	This dataset is necessary for us to find out the total number of elderly population in a specific Subzone.	https://data.gov.sg/dataset/singapore-residents-by-subzone-and-type-of-dwelling-june-2016
7.	Singapore Residents by Subzone, Age Group and Sex, June 2016 (Gender)	This dataset is necessary for us to find out the total number of elderly population.	https://data.gov.sg/dataset/singapore-residents-by-subzone-age-group-and-sex-june-2016-gender
8.	Total Number of Healthcare facilities in Singapore	This dataset is necessary for us to locate all the neighborhood clinics in Singapore and find out which Subzone they belong to, so as to aid in our proximity analysis with the dwellings. As this data is not readily available to us, we will need to perform web scraping to "scrape" the data off the Singapore YellowPages website. A Python script can help us achieve the following and more details can be found below.	https://www.yellowpages.com.sg/

Code Snippet 1	Code Snippet 2

The code snippets above shows how we can perform web scraping using a Python script. The script mainly does the following in a nutshell:

1. Visit through each page of the YellowPages Singapore's clinics results in a loop.
2. Make use of XPATH expressions to retrieve the content (clinic name, address, latitude and longitude) located at specific HTML attributes.
3. Check whether the retrieved clinic info is a Dental clinic, if yes we will SKIP the result, if not we will proceed to save it.
4. When all pages are visited, the retrieved clinics information will be parsed and stored into a .CSV file with the respective columns.

PROJECT CHALLENGES

No.	Key Technical Challenges	Description	Proposed Solution	Outcome
1.	Unfamiliarity with R packages and R Shiny	Our team may encounter the use of additional R resources that were not taught in class.	- Independent Learning on R packages and R Shiny - Browsing the official RDocumentation website for support and reference - Research for online tutorials that have a specific use case for certain R packages	We managed to solve the mentioned challenge with the following resources: -
2.	Data Cleaning and Transformation	As we need to collect the data from various sources, they may have different attributes such as the Coordinate Reference System (CRS), units of measurement and etc.	Adopt a standardized process of cleaning the data, focusing with what we only need. Most of the datasets used for our project can be found in our Hands-On or Take-Home exercises and we can rely on those existing data.	We managed to solve our technical challenge with the following: -
3.	Limitations & Constraints in Datasets	There are certain assumptions that we need to make based on the context and purpose of our project, such as the average number of doctors in a particular clinic, which cannot be derived from our datasets.	Working out with the team together and figuring out a reasonable and valid assumption, together with adequate online research and consultation with Prof. Kam.	We managed to solve our technical challenge with the following: -
