Overview
We have completed the primary functionalities of the project scope - the primary architecture of the for each modules. We are currently progressing into the secondary module - Accessibility Module. The project schedule is segregated into different phases to provide an overview for each development phase.
Project Progress
Scope Changes:
- Schedule is categorized in Phases, followed by Iterations in each Phases, to give a better overview on what the Team aims to achieve for each stage of development.
Time Constraint:
- Time was required to explore new technologies for the application such as D3 library for Data-Visualization Module, Leaflet for Geo-Visualization Module and PostGIS for Geo-Processing Module.
- Increased complexity in Phase 3, for Data-Visualization, in preparation for the first User Experience Test with URA to gather feedback on application.
Technical Difficulties:
- Processing filtered data sets in PostGIS database.
Project Management
Project Status
Changes that were made:
- Made Tabular View Module part of Data-Visualization Module because this involves just developing of a simple table.
- Made Coordinate Linked View Module part of Geo-Visualization Module because this involves interaction between clicking of icons on the map with the charts.
- Replaced Analytics Module with Accessibility Module because URA already has a group of Masters students helping them in this area.
Completed Features:
Module | Feature | Description |
---|---|---|
Data Upload | Upload data into application | Update: This function has been replaced with the PostGIS database where datasets are stored. |
Geo-Processing | Geo-database | Internal processing of data to transaction points is implemented. This is for accessibility module. |
Geo-Visualization | Geospatial analysis | An interactive visual map-based data is implemented. |
Data-Visualization | Visual analysis | Interactive charts are implemented with filtering functions. |
About Accessibility Module:
This module involves identifying the accessibility of a property to the nearby facilities. The identified facilities serves the primary needs of the residents, based on walkability or transport. These facilities include bus-stops, primary and secondary schools, parks, community centers, etc. The purpose of having an Accessibility Index is to observe the relationship between Accessibility with the price of the Property.
Given that the main focus of this project is building PostGIS database, this module will be heavily reliant on PostGIS database through processing calculations at the back-end. Further explanation on PostGIS architecture will be in Technical Complexity.
Project Schedule (Plan Vs Actual)
Project Schedule (Plan Vs Actual) - Acceptance
Comments by The Team:
- Scope of modules were overlooked. Some were too simple, while the rest were too complex.
- Completion of modules were not ranked based on the primary to secondary needs. Instead, modules scheduled based on the importance and simplicity.
- The team was unclear of the requirements and scope when this was planned, however, changes were made along the way, reflecting on the completion deadline of each modules.
Changes that were made:
- Added phases to the schedule as a top-level overview for each iterations. The purpose of this is to give an overview of the development progress for the project.
- Schedule has been edited after the first iteration in the picture above. The newly edited planned schedule is shown below.

Not aware that coordinates returned by invoking OneMap API are in SVY21 projection system. Hence map points are in wrong positions. | High Impact - 5 | Make use of external JavaScript libraries for geo-projection conversion, called SVY21(). | 09/01/2015 | 1000 | 11/01/2015 | 1200 | 3 |
When user keys in a search query, search function might return global results instead of Singapore results. | Low Impact - 1 | Make the search function localised in Singapore instead of in a global scale. | 29/01/2015 | 1400 | 31/01/2015 | 1600 | 3 |
Iteration 4: Architecture Designs | |||||||
---|---|---|---|---|---|---|---|
Error Message | Impact | Solutions | Date of Bug Faced | Time of Bug Faced | Date of Bug Solved | Time of Bug Solved | Days for Debug |
Cannot retrieve the data from the PostGis database due to the mismatch of column names. | High Impact - 5 | Standarise the column name between the the java and javascipt files. | 14/02/2015 | 1400 | 15/02/2015 | 1600 | 2 |
Inconsistent filter criteria when the pie chart is changed to row chart and vice-versa for the onclick event. | Low Impact - 1 | Apply the filter criteria to the rendering of the chart for the onclick event. | 13/02/2015 | 0900 | 14/02/2015 | 1200 | 2 |
Polygon selection of the markers on the map does not affect the chart popup. | Low Impact - 1 | Change to the correct div id of the chart popup. | 15/02/2015 | 1300 | 16/02/2015 | 1600 | 2 |
