This project aims to build a robust machine learning model to predict key water quality parameters across river locations. The training dataset includes geotagged measurements collected between 2011–2015 from ~200 sites. The task is to enhance predictions by incorporating publicly available geospatial and environmental datasets such as Landsat Level‑2 satellite imagery, TerraClimate, or other open-source data sources. Beyond prediction accuracy, the project requires identifying key drivers of water quality variation through feature importance analysis. Supporting material—including guidance documents, benchmark notebooks, and 2 datasets.

I already have the core shapefile ready and now need a clean, browser-based application—similar in look and feel to —that lets visitors explore, filter and analyse that data in real time. The emphasis is on geographical data analysis: users should be able to zoom, pan and query the layer to reveal attribute information, run basic spatial statistics (area, distance, buffer, etc.) and toggle thematic views such as colour-coded classifications. On top of that analysis layer, the interface must let a visitor highlight specific areas with an on-screen tool (simple polygon / free-hand highlighter). They don’t need to add text or draw arbitrary shapes—just select one or more zones, see the combined stats and optionally export the highlighted geometry to GeoJSON. Key expe...
