Abstract
Trash and litter continue to grow throughout California, causing problems for both communities and the environment. To address these issues, the Trash Rapid Assessment Data Exchange (TRADE) project developed a system that collects and maintains litter data across California. This system enables permittees to visualize and manage their litter data, allowing them to better understand the extent of the litter problem and develop effective strategies to fight against it. It was created with the help of citizen scientists across California by taking litter assessments at various sites. However, having such a system requires efficient quality control measures to ensure that the data is reliable and accurate. This master’s project enhances the previous TRADE system through three main implementations: refining the data automation to improve efficiency, creating city-specific dashboards to allow cities to review and manage their incoming data, and introducing data provenance to trace modifications made to litter data. These improvements will help ensure the integrity of the data and provide stakeholders with more accurate litter data.
