Presentation Abstract
In agricultural science, a high quality of field-collected data is essential for reliable research results. However, ensuring quality often requires time-consuming data cleansing in a post-processing step or even repeated measurements. In this presentation, we showcase our ongoing development of an interface for an in-field data quality assessment. Designed to assist scientists during data collection, it allows them to identify quality issues already on-site, enabling immediate action to address potential problems.
By integrating the quality assessment into the data collection process, we further argue that we can lower the barrier to uploading quality-related metadata with the data, thereby improving data reusability. Our interface implements light-weight algorithms that enable its use on mobile devices without requiring a connection to a server. From a methodological perspective, our current focus lies on time series data. Specifically, we are providing summary statistics as well as state-of-the-art algorithms for outlier analysis and data clustering. Algorithmically, we follow a sliding window technique which enables memory-efficient computations that are essential when using mobile devices with limited memory capacity.
We present first results from an early stage of the development as well as planned research directions, such as the integration with existing data collection workflows.
