This assignment is composed of two parts: a) Programming Part, and b) Written Part. The purpose of this assignment is to get you familiar with the concepts of multimedia systems, through the realization of Smart City Use Case(s). In essence, you are required to acquire appropriate data streams from https://data.gov.hk/, and based on these data to craft up use cases and derive insights in relation to smart city initiatives. There is no fixed scope nor limit for the smart city use cases, you are free to choose appropriate use cases as you see fit.
The programming part requires you to implement an application that fetch data streams from https://data.gov.hk/, data analysis and correlation, as well as dashboards to present insights in relation to your selected smart city use cases. The written part, on the other hand, requires you to write a report, in which you explain in details your smart city use cases, and corresponding implementation details.
Please note that this is a group programming assignment. We expect two students working together to complete this assignment.
To fulfil the programming part, you are required to do your programming works in the node-red environment. Please follow the AWS EC2 Instance Setup instructions to launch an EC2 instance for your programming environment. After successful launch, your EC2 instance will be configured with a node-red programming environment as well as a MongoDB instance for data storage.
An example has been provided in the file HKO.Flow.json, and you should be able to import it into your node-red environment as shown in Figure 1. This is essentially a demonstration of how to fetch temperature data from Hong Kong Observatory, and plots the
historical temperature of various Hong Kong locations up to the last 24 hours as illustrated in Figure 2.
Figure 1: Example Node-Red Flow for fetching weather data from Hong Kong Observatory.
Figure 2: Chart showing historical temperature data in various locations up to last 24 hours.
The programming part requires you to implement an application that fetch data streams from https://data.gov.hk/, data analysis and correlation, as well as dashboards to present insights in relation to your selected smart city use cases. Be sure to start storing data earlier for your subsequent work as it takes time to accumulate enough data for your smart city use cases development.
You are required to write a report, in which you explain in details your smart city use cases, and corresponding implementation details, data storing approach, and explain how each dashboard present the corresponding smart city use case insights.
Assignment must be submitted through the moodle course web. The following files have to be submitted as a one single zip file:
1. Exported flow file in your node-red environment.
2. The grader.pem.txt key-pair file.
3. An empty file with name that is the IP address of your EC2 instance.
1. Late submission is subjected to the penalty of 5% deduction per day.
2. Submission late for more than one week will not be entertained.
3. Programs that cannot be compiled will NOT be graded.
4. Plagiarism will be heavily penalized.
